This brochure will provide you with the information you need to benefit the most
from your tekmarNet

thermostat. Please visit www.tekmarControls.com for more

detailed information on this or any other tekmar product.

This thermostat provides heating and cooling for one zone in your building. It will
maintain your air temperature with an on board room sensor. Floor temperature
control may also be enabled in this thermostat when a floor sensor is installed.
This thermostat can lower its temperature setting at night or when you are away
from the house.

Display of the time, schedule and the away key on the Home screen is optional and
can be turned on or off in the programming menus.

To enter the programming menus, press and hold the Home button for 3 seconds.

Touchscreen Adjustments

The touchscreen of this thermostat makes it easy to change commonly used settings.
Touch any item to adjust its setting. You will hear a “tick” sound each time you touch
the display. When you are finished making changes, touching the Home button will
return to the Home screen. If you do not touch the screen for 3 seconds, the Home
screen is automatically displayed.

Adjust the Temperature - Temporary Hold

Temporary hold allows a user to change the temperature for a period of time and then
automatically return to the permanent temperature setting. This is especially useful
in commercial buildings that are in use for short amounts of time. When selected,
touching the up or down arrows changes the temperature for either 3, 6, 9 or 12
hours. If the thermostat is using a schedule, ‘Schd’ provides a temporary hold until
the next schedule event time. After the temporary hold time expires, the thermostat
returns to normal operation. By default, the temporary hold feature is off.

Adjust the Temperature

To change the heating or cooling set temperature, touch the or arrows to
select a preferred temperature setting. Press the home button to accept the setting
or leave the screen untouched for several seconds. To toggle between changing
the heating or cooling setting, press the H <> C key. This thermostat is capable of
controlling the floor or air temperature.

Note:

The temperature is not adjustable if the thermostat is in the Away scene, the

Off mode or has been set to the “Secure” access level by the installer.

Screen Clean Menu

Entering the Screen Clean menu gives you 30 seconds to clean the thermostat and
display with a moist cloth. Do not use solvents to clean the thermostat.

Set Temp Menu

Entering the Set Temp menu allows you to permanently change both the day

and night temperature settings for both heating, cooling.

If your thermostat is being used for radiant floor heating, a floor sensor can be
connected and floor minimum day

and night temperatures can be set. Radiant

floors heat the air by raising the floor temperature. Setting a floor temperature is a
way of enhancing the comfort of your living space.

Air Temperature Only

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

If there is only an air temperature sensor (no floor sensor), the thermostat operates
to control your desired air temperature.

Floor and Air Temperature

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

If the air sensor is turned on and a floor sensor is connected, the thermostat will
maintain your desired air temperature as well as a minimum floor temperature.

This operation is recommended for areas with large windows that allow the sun to
shine into a room and keep it warm without the need for heat. This can allow the
floors to cool off during the afternoon. When the sun goes down, it can take a long
time for the floors to get warm again. This may cause the room to cool off too much in
the early evening. A floor minimum setting can help with this condition by maintaining
a floor minimum temperature. Keep in mind the floor minimum temperature will
override the air temperature, and if set too high, may overheat the room.

This operation is also recommended for rooms with hardwood floors. Setting floor
minimum and maximum temperatures is a way of enhancing the comfort of your
living space while protecting your floor coverings.

include:

Turning off the schedule (OFF)
Operate a schedule that applies only to this thermostat zone (ZONE)
The ability to operate one of the four system-wide schedules as a master (Schedule
Master 1 through 4*)
Join one of the four system-wide schedules as a member (Schedule Member

The schedules can be repeated every:

24 hours
7 days (week)

A 7 day schedule allows a unique time to be set to change the temperature for each
day of the week.
The schedule also includes a “SKIP” option that allows the programmable schedule to
skip a temperature change and remain at the previous temperature setting. The “SKIP”
setting can be found between 11:50 PM (23:50 hours) and 12:00 AM (0:00 hours).
When a programmable schedule is selected, there is a time delay for the room to
warm up or cool down from the temperature to the temperature. The thermostat
has the option to use Optimum Start to predict the heat up or cool down rate of
the room. When Optimum Start is set to On, the heating or cooling is started in
advance to allow the room to reach the Set Room temperature at the time set in
the programmable schedule.
