General

CYCLES PER HOUR (HEAT CYCLE)

The thermostat operation is based on cycles per hour. The number of cycles per hour is
adjustable through the HEAT CYCLE settings in the Adjust menu. During each cycle that
heating is required, the thermostat turns on the Heat relay for a calculated amount of time.
This amount of time is the “on time”. The on time is calculated based on the requirements of
the zone. If the zone requires more heating, the ON time is increased. If the zone requires
less heat, the ON time is reduced.

In order to prevent short cycling of the heating relay(s), the thermostat ensures that the
relay(s) remains on or off for a minimum amount of time.

An Auto Cycle setting is available for the
heating cycle. This setting allows the
thermostat to determine the best number of
cycles per hour that balances both temperature
swings and equipment cycles.

The early start function ensures that the
zone is up to the proper temperature at the
beginning of each period. The thermostat
learns the recovery rate over multiple setback
events in order to determine the proper lead
time for the zone. If both an air sensor and
a slab sensor are used, the lead time is the
greater of the air sensor’s or the slab sensor’s
requirements.

AUXILIARY SENSORS

The thermostat has a single built-in sensor to measure air temperature at the thermostat. In
addition to the built-in sensor, the thermostat has terminals to connect up to two separate
sensors. These sensors can be either indoor sensors, slab sensors, a remote sensor, or
an outdoor sensor.

3 of 16

D 510 - 02/12

Indoor Sensor

An indoor sensor is used to measure the air temperature in the zone that the thermostat is
controlling. The temperature being read by the indoor sensor is used in the calculations of
the on times for the relay in the thermostat. Either one or both of the auxiliary sensor inputs
can be configured for indoor sensors. This setting is made through the Adjust menu of the
thermostat. If more than one sensor, either the built-in sensor or an auxiliary sensor set as
an indoor sensor, is being used to measure the zone temperature, the temperature of the
active sensors is averaged and used to calculate the on time of the relay.

Slab Sensor

A slab sensor is used to measure the slab temperature in the zone that the thermostat
is controlling. The temperature being read by the slab sensor is used in the calculations
of the on time for the Heat relay and allows the thermostat to operate the slab between
the slab minimum and slab maximum settings. If more than one slab sensor is used, the
slab temperatures are averaged by the thermostat.

Remote Sensor

A single remote sensor can be connected to the thermostat. The temperature measured
by a remote sensor does not affect the on time of the relay and is only used for display
purposes.

Outdoor Sensor

A single outdoor sensor can be connected to the thermostat. The temperature measured
by an outdoor sensor does not affect the on time of the relay and is only used for display
purposes.

ACCESS LEVELS

The tekmar Programmable Thermostat has two
access levels. These access levels restrict the
number of items available in the menus of the
thermostat. The two access levels are User and
Installer. This selection is made using the DIP
switch located on the circuit board inside the
thermostat.

The Installer access level allows the installer to
adjust all of the settings in the thermostat including
those required to match the thermostat to the
mechanical system and the devices used.

The User access level allows the end user to
adjust the time, temperatures and schedules
used by the thermostat.

Sequence of Operation

ONE STAGE HEAT

Air Sensor(s) Only Operation

When operating with only an air sensor, the on time for the Heat relay is calculated to
satisfy the requirements of the air sensor.

Slab Sensor Only Operation

When operating with only a slab sensor, the on time for the Heat relay is calculated to
satisfy the requirements of the slab sensor. The thermostat operates to maintain the slab
at the minimum slab temperature setting.

NOTE:

Operating with only a slab sensor can lead to either overheating or underheating

of the space.

Air and Slab Sensor Operation

When operating with both air and slab sensors, the thermostat calculates an on time for
the Heat relay to satisfy the slab sensor’s requirements and an on time to satisfy the air
sensor’s requirements. The Heat relay operates for the longer of these two on times.

During light heating loads, overheating can occur due to the minimum slab temperature
requirements.

During heavy heating loads, the maximum slab temperature setting limits the on time of
the Heat relay. In this situation, underheating can occur.

Mode

Heat

In the heat mode, the Heat relay is operated to satisfy the temperature requirement
of the zone.

Off

In the Off mode, the Heat relay is not operated.

NOTE:

If an air or slab sensor is active in the Off mode, a freeze protection is enabled

that allows the Heat relay to be operated to keep the zone above 35°F (2°C).

Slab Sensor 079

The tekmar Slab Sensor 079 has a stainless steel sleeve which is designed for use in
concrete, thin-set or grout. The 079 is supplied with 10’ (3 m) of 2 conductor zipcord.

STEP ONE

INSTALLING THE SENSOR

New Installations

Thin-Set or Thin-Pour Applications

If the floor covering is to be installed over either
a thin-set or thin-pour material of sufficient
depth, the 079 slab sensor can be placed
directly into either the thin-set material or the
thin-pour material and covered over. Ensure
that the sensor is located in such a position that
the attached wire is able to reach to a suitable
junction location. Splices within the thin-set or

(45 mm) long should be cut to accommodate the sensor. The sensor should be located
mid way between the heating elements to ensure a proper temperature reading.

Thin-set

Electric
Cables

thin-pour should be avoided to ensure trouble free operation. The sensor should be located
mid way between the heating elements to ensure a proper temperature reading.

If a thin floor covering is to be installed directly
to the subfloor, a groove 1/8” (4 mm) wide by
1/16” (2 mm) deep can be cut into the surface of
the subfloor to accommodate the wire for the
sensor. Ensure that the sensor is located in
such a position that the attached wire is able
to reach to a suitable junction location. Splices
under the floor covering should be avoided to
ensure trouble free operation. A groove 3/16”
(5 mm) wide by 3/16” (5 mm) deep by 1-3/4”

Hardwood

Subfloor

Thick Floor Coverings (greater than 3/8” (10 mm))

If a thick floor covering is to be installed directly to the subfloor, a groove 1/8” (4 mm) wide
by 1/16” (2 mm) deep can be cut into the back of the flooring material to accommodate
the wire for the sensor. Ensure that the sensor is located in such a position that the
attached wire is able to reach to a suitable junction location.

Splices under the floor covering should be
avoided to ensure trouble free operation. A
groove 3/16” (5 mm) wide by 3/16” (5 mm)
deep by 1-3/4” (45 mm) long should be cut to
accommodate the sensor. The sensor should be
located mid way between the heating elements
to ensure a proper temperature reading.

NOTE:

If it is not practical to cut a groove in the surface covering, follow the installation

method used for thin floor coverings.

the sensor location. Ensure that the sensor is
located in such a position that the attached wire
is able to reach to a suitable junction location.
Splices within the grout should be avoided to
ensure trouble free operation. Remove the
appropriate grout line and place the sensor and
wire in the floor. Re-grout the area.

Subfloor

Installing the Sensor to the Bottom of a Subfloor

If the sensor is to be installed to the bottom of a subfloor, cut a piece of 1” (25 mm)
thick rigid insulation into a 6” (150 mm) by 6” (150 mm) square. A groove 3/16” (5
mm) wide by 3/16” (5 mm) deep by 1-3/4”
(45 mm) long should be cut into the insulation
to accommodate the sensor. Place the sensor
in the groove and sandwich the sensor between
the insulation and the subfloor. Use a suitable
fastening method to affix the insulation to the
subfloor.

STEP TWO

WIRING AND TESTING THE SENSOR

Caution:

Do not run sensor wires parallel to telephone or power cables. If the sensor wires

are located in an area with strong sources of electromagnetic interference, shielded cable
or twisted pair should be used or the wires can be run in a grounded metal conduit.

The Slab Sensor 079 is supplied with 10’ (3 m) of cable. If a longer length is required, 24
AWG or larger wire can be spliced onto the two wires from the sensor. The splices should
be properly soldered and protected in an accessible junction box. Follow the sensor testing
instructions given in this brochure and then connect the wires to the control.

Thermostat Installation

NOTE:

If the thermostat is to be used for remote sensing (i.e. The built-in air sensor is

disabled and an indoor sensor is being used.) Mount the thermostat in the desired location
in an appropriate manner.

STEP THREE

ROUGH IN WIRING

•

18 AWG or similar wire is recommended for all 24 V (ac) wiring.

•

All wires are to be stripped to 1/4” (6 mm) to ensure proper connection to the control.

•

Run wires from the 24 V (ac) power to the thermostat. Use a clean power source to

ensure proper operation.

•

Run wires from the heating device to the thermostat.

STEP TWO

REMOVING THE FRONT COVER

Place a screwdriver or similar object into the small slot
located in the top of the thermostat. Push the screwdriver
against the plastic tab and pull the top of the front cover
so that it pivots around the bottom edge of the base.

STEP THREE

MOUNTING THE BASE

Item

Remove cover

Push tab

The thermostat should be installed on an interior wall
of the desired zone approximately 5’ (1.5 m) above the
floor. Do not mount the thermostat in a location that may
be affected by localized heat sources or cold drafts. It
may be necessary to install a draft barrier behind the
thermostat to prevent air from blowing through the wiring
hole and affecting the thermostat’s built-in sensor.

Mount the base directly to the wall using two #6
1” screws. The screws are inserted through the
mounting holes and must be securely fastened
to the wall. If possible, at least one of the screws
should enter a wall stud or similar surface. If the
thermostat is to be mounted to a 2” x 4” electrical
box, order an Adaptor Plate 007. This plate
mounts to the electrical box and the thermostat
mounts to the plate. Ensure that the electrical box
does not provide cold air to the thermostat.

STEP FOUR

WIRING THE THERMOSTAT

24 V (ac) Power

(Refer to the examples on the following pages.)

24 V (ac) power

Connect the 24 V (ac) power to the R and C terminals (1 and 2) of the thermostat. This
connection provides power to the microprocessor and display of the thermostat.

Auxiliary Sensors (S1 and S2)

Either an indoor, slab, or remote sensor may be connected to the S1 input. Connect the
two wires from the auxiliary sensor to the Com and S1 terminals (3 and 4).

Either an indoor, slab, or outdoor sensor may be connected to the S2 input. Connect the
two wires from the auxiliary sensor to the Com and S2 terminals (3 and 5).

Heat Relay

The Heat terminals (6 and 7) are an isolated output. There is no power available on
these terminals from the thermostat. These terminals are to be used as a switch for a
24 V (ac) circuit. This circuit can operate a low current 24 V (ac) device directly or an
external relay to enable a line voltage or high current device.

Limited Warranty

The liability of tekmar under this warranty is limited. The Purchaser, by taking receipt of

any tekmar product (“Product”), acknowledges the terms of the Limited Warranty in effect at the time of
such Product sale and acknowledges that it has read and understands same.

The tekmar Limited Warranty to the Purchaser on the Products sold hereunder is a manufacturer’s pass-
through warranty which the Purchaser is authorized to pass through to its customers. Under the Limited
Warranty, each tekmar Product is warranted against defects in workmanship and materials if the Product
is installed and used in compliance with tekmar’s instructions, ordinary wear and tear excepted. The pass-
through warranty period is for a period of twenty-four (24) months from the production date if the Product is
not installed during that period, or twelve (12) months from the documented date of installation if installed
within twenty-four (24) months from the production date.

The liability of tekmar under the Limited Warranty shall be limited to, at tekmar’s sole discretion: the cost of parts
and labor provided by tekmar to repair defects in materials and / or workmanship of the defective product; or to
the exchange of the defective product for a warranty replacement product; or to the granting of credit limited to the
original cost of the defective product, and such repair, exchange or credit shall be the sole remedy available from
tekmar, and, without limiting the foregoing in any way, tekmar is not responsible, in contract, tort or strict product
liability, for any other losses, costs, expenses, inconveniences, or damages, whether direct, indirect, special, sec-
ondary, incidental or consequential, arising from ownership or use of the product, or from defects in workmanship
or materials, including any liability for fundamental breach of contract.

The pass-through Limited Warranty applies only to those defective Products returned to tekmar during the war-
ranty period. This Limited Warranty does not cover the cost of the parts or labor to remove or transport the defec-
tive Product, or to reinstall the repaired or replacement Product, all such costs and expenses being subject to
Purchaser’s agreement and warranty with its customers.

Any representations or warranties about the Products made by Purchaser to its customers which are different from
or in excess of the tekmar Limited Warranty are the Purchaser’s sole responsibility and obligation. Purchaser shall
indemnify and hold tekmar harmless from and against any and all claims, liabilities and damages of any kind or
nature which arise out of or are related to any such representations or warranties by Purchaser to its customers.

The pass-through Limited Warranty does not apply if the returned Product has been damaged by negligence by
persons other than tekmar, accident, fire, Act of God, abuse or misuse; or has been damaged by modifications,
alterations or attachments made subsequent to purchase which have not been authorized by tekmar; or if the Prod-
uct was not installed in compliance with tekmar’s instructions and / or the local codes and ordinances; or if due to
defective installation of the Product; or if the Product was not used in compliance with tekmar’s instructions.

THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, WHICH THE GOVERNING
LAW ALLOWS PARTIES TO CONTRACTUALLY EXCLUDE, INCLUDING, WITHOUT LIMITATION, IMPLIED WAR-
RANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, DURABILITY OR DESCRIP-
TION OF THE PRODUCT, ITS NON-INFRINGEMENT OF ANY RELEVANT PATENTS OR TRADEMARKS, AND
ITS COMPLIANCE WITH OR NON-VIOLATION OF ANY APPLICABLE ENVIRONMENTAL, HEALTH OR SAFETY
LEGISLATION; THE TERM OF ANY OTHER WARRANTY NOT HEREBY CONTRACTUALLY EXCLUDED IS LIM-
ITED SUCH THAT IT SHALL NOT EXTEND BEYOND TWENTY-FOUR (24) MONTHS FROM THE PRODUCTION
DATE, TO THE EXTENT THAT SUCH LIMITATION IS ALLOWED BY THE GOVERNING LAW.

Product Warranty Return Procedure

All Products that are believed to have defects in workmanship or materi-

als must be returned, together with a written description of the defect, to the tekmar Representative assigned to
the territory in which such Product is located. If tekmar receives an inquiry from someone other than a tekmar
Representative, including an inquiry from Purchaser (if not a tekmar Representative) or Purchaser’s customers,
regarding a potential warranty claim, tekmar’s sole obligation shall be to provide the address and other contact
information regarding the appropriate Representative.
