Rough-In Wiring

Line Voltage Wiring

-----------------------------------------------------------------------------------

In most cases, the control can be mounted directly to a wall
without the need for any line voltage connections.

As an option, the control may be mounted to a 4” x 4”
electrical junction box so that the high voltage electrical
connections for the transformer are safely contained.

For ease of service, the circuit breaker or power disconnect
should be located in reasonably close proximity to the
equipment.

All line voltage wire connections are recommended to
be pulled inside a flexible or solid conduit. Always follow
proper wiring practices, building and electrical codes for
your jurisdiction.

Each cable must be pulled to the electrical junction box. It
is recommended to label each cable for easy identification.
All line voltage wires should be stripped to a length of 1/2”
(13 mm).

The control requires an external transformer. A tekmar
Transformer 009 (or 009K which includes a 4”x 4” electrical
box) can supply up to 40 VA, and includes an in-line fuse
to protect the transformer and control.
In order to correctly size the external transformer, all loads
connected to the control must be taken into account.
When adding up the loads, consider the following:

tekmarNet

2 Thermostats draw approximately 2 VA each.

Each zone valve must be sized for peak load. This can be
obtained by multiplying the peak current draw (in Amps)
by 24 V (ac).

•
•

The total power capacity of the power supply should be
larger than the total load of all the devices connected
to the control. This total load must not exceed 100 VA.
Multiple tekmar Transformer 009’s can be wired together
to increase total VA capacity.

Testing the Control Wiring

Testing the Power

-----------------------------

If the control Power light does not turn on, check the Input
Power wiring terminals using an electrical multimeter. The
voltage should measure between 21.6 to 26.4 V (ac). If the
voltage is below this range, measure the line voltage side
of the transformer. The voltage should measure between
103.5 to 126.5 V (ac).

Testing the Thermostats

----------------------

If the thermostat display turns on, this indicates that the
thermostat is operating correctly and there are no electrical
issues. In the event that the display is off, or the display is
cycling on and off, follow this procedure.

1. Remove the tN2 wires from the thermostat.
2. Use an electrical meter to measure DC voltage between

the tN2 terminals.

If the DC voltage is 0 V (dc) for 20 seconds, then there is
an open or short circuit in the tN2 wires. If the DC voltage
is 0 V (dc) for 10 seconds and then is 23 to 24 V (dc) for 5
seconds, this indicates the wiring is correct.

3. Connect the thermostat to the tN2 wires from a zone

on a House Control, Wiring Center, or Zone Manager.

4. If the thermostat display is off, or is cycling on and off,

move the thermostat to the next available zone on the
House Control, Wiring Center, or Zone Manager.

If the thermostat display remains permanently on, there
may be a fault with the previously tried zone on the House
Control, Wiring Center, or Zone Manager.

If the thermostat display continues to be off, or is cycling
on and off, there may be a fault on the thermostat.
If a fault is suspected, contact your tekmar sales representative
for assistance.

Testing the Zone Output

----------------------

Turn up the thermostat connected to Zone 1 until it calls
for heat showing the H1 on the display. Using an electrical
meter, measure the voltage between the zone valve and
the common (C) terminals. The voltage should measure
between 21.6 V (ac) and 26.4 V (ac). Repeat for Zones 2,
3, and 4.

Sequence of Operation

tekmarNet

System

Section A

tekmarNet

is a family of products that use communication

to operate the HVAC system in a comfortable and efficient
manner. The Wiring Center is a zoning component in
a tekmarNet

system and requires tekmarNet

2 (tN2)

Thermostats to be directly connected to it.

The tekmarNet

4 (tN4) Expansion terminals can link the

Wiring Center with other tekmarNet

components:

House Controls 400, 401, 402, 403 - Provides boiler and
DHW control

•

Wiring Centers 313, 314, 315, 316 - Add additional zones
tN4 Thermostats - Add thermostats
tN4 Timer 033 - Adds 4 programmable schedules
tN4 User Switch 479 - Provides a system override for
vacations and holidays
tN4 Setpoint Control 161, 162 - Control hot tubs, pools
and more

•
•
•
•

•

Relay Outputs

Section B

Synchronized End Switch Operation

----------

tekmarNet

2 thermostats provide the Wiring Center with

a synchronized end switch feature. This ‘synchronizes’
the start times of the zones and reduces short cycling of
equipment connected to the wiring center’s end switch.
The net effect is increased system efficiency and reduced
wear on equipment.

The End Switch relay (‘XX’) closes and the end switch
LED turns on. The switch remains closed as long as any
zone is calling for heat. This can provide a boiler demand
to a tekmar reset control, or provide a boiler enable to a
boiler’s TT terminals.

If the Wiring Center is connected to a tN4 bus, all
communication messages will pass through the 313’s
tN4 expansion connection. tN4 messages are required
in order to create a boiler demand on a device such as
a tekmar House Control 400.

24 V (ac) Zone Relay Operation

----------------

When a thermostat calls for heat, it sends a message to
the Wiring Center and the corresponding zone LED turns
on. Power is then supplied to the appropriate zone output
as indicated by the LED.

•

ZONE 1

The zone 1 thermostat is calling for heat
and the 24 V (ac) output is energized.

ZONE 2

The zone 2 thermostat is calling for heat
and the 24 V (ac) output is energized.

ZONE 3

The zone 3 thermostat is calling for heat
and the 24 V (ac) output is energized.

ZONE 4

The zone 4 thermostat is calling for heat
and the 24 V (ac) output is energized.

POWER

24 V (ac) is being applied to the Wiring
Center to provide it with power.

END SWITCH

At least one of the zone thermostats are
calling for heat and the end switch relay
output is closed.

Zone LED Flashing

----------------------------

The zone has an open or short circuit and communication
to the thermostat on the zone has been interrupted. Check
the wiring between the thermostat and the Wiring Center
for open or short circuits. If the thermostat was intentionally
removed, power the Wiring Center off for 10 seconds.

11 of 12

D 313 - 11/10

Network Schedules

----------------------------

Adding a schedule to a tekmarNet

system is both easy

and valuable. A Timer 033 provides scheduling with up to
4 events per day for every tekmarNet

Thermostat. Turning

down the room temperatures when they are unoccupied
reduces boiler on-time and energy consumption which
helps save money and the environment.

One-Touch Economy

--------------------------

A User Switch 479 allows for one-touch overrides of the
system. For example, if leaving the building for vacation,
simply press the “Away” button and all the thermostats
will immediately operate at a lower temperature, instead
of having to walk around the building lowering the heating
temperature setting and raising the cooling temperature
setting on each thermostat.

Energy Saving Features

Section C

Zone Synchronization

-------------------------

Another feature of the Wiring Center is Zone Synchronization.
In typical zoned systems, the thermostats operate on a
stand-alone basis. This means that a zone turns on and off
as required without any regard for other zones. The net effect
is random operation of the zones causing short cycling of
the heat source. tekmarNet

thermostats communicate to

ensure that their cycles are synchronized. Energy is saved
by ensuring zones requiring heat operate on the same cycle,
therefore reducing short cycling of the boiler.

Thermostats have a differential of +/- 1.5°F (0.8°C) of the temperature setting.
Due to the display rounding numbers up, heating can appear on when the
temperature is 2°F (1.1°C) above the setting. This is normal operation.

LED shows zone off

Ensure zone valve terminals measure 0 V (ac). Measuring 0 V (ac) indicates
mechanical zone valve may have failed in open position. Measuring 24 V (ac)
indicates control relay may have failed.

Single zone under
heating

LED shows zone on

Ensure zone valve terminals measure 24 V (ac). Measuring 24 V (ac) indicates
mechanical zone valve may have failed in closed position. Measuring 0 V (ac)
indicates control relay may have failed.

LED shows zone off

Check the thermostat to see if it is calling for heat (H1 displayed on the screen).

Zone LED flashing

The zone has an open or short circuit and communication to the thermostat on
the zone has been interrupted. Check the wiring between the thermostat and
the Wiring Center for open or short circuits. If the thermostat was intentionally
removed, power the Wiring Center off for 10 seconds.

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 docu-
mented 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 prod-
uct; or to the exchange of the defective product for a warranty replace-
ment 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 liabil-
ity, for any other losses, costs, expenses, inconveniences, or damages,
whether direct, indirect, special, secondary, incidental or consequential,
arising from ownership or use of the product, or from defects in work-
manship or materials, including any liability for fundamental breach of
contract.

The pass-through Limited Warranty applies only to those defective Prod-
ucts returned to tekmar during the warranty period. This Limited War-
ranty does not cover the cost of the parts or labor to remove or transport
the defective 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 Lim-
ited Warranty are the Purchaser’s sole responsibility and obligation. Pur-
chaser 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 Pur-
chaser to its customers.

The pass-through Limited Warranty does not apply if the returned Prod-
uct 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 Product 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 WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
A PARTICULAR PURPOSE, DURABILITY OR DESCRIPTION OF THE
PRODUCT, ITS NON-INFRINGEMENT OF ANY RELEVANT PATENTS
OR TRADEMARKS, AND ITS COMPLIANCE WITH OR NON-VIOLA-
TION OF ANY APPLICABLE ENVIRONMENTAL, HEALTH OR SAFETY
LEGISLATION; THE TERM OF ANY OTHER WARRANTY NOT HEREBY
CONTRACTUALLY EXCLUDED IS LIMITED SUCH THAT IT SHALL NOT
EXTEND BEYOND TWENTY-FOUR (24) MONTHS FROM THE PRODUC-
TION 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 materials 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 informa-
tion regarding the appropriate Representative.
