Sequence of Operation

Heating Operation
The Heat On symbol is shown on the display when the thermostat is heating. Heating for freeze protection is provided whenever the air or floor temperature falls below 40°F (4.5°C), regardless of operating mode.
Regular Heating
W1 relay is on when the air temperature falls 1.5°F (1°C) below the Heat To setting. When the temperature reaches the Heat To setting, the relay turns off.
Radiant Floor Heating
When Radiant Floor Heating is selected in the setup menu, the W1 relay operates using Pulse Width Modulation. This improves comfort for radiant systems with high mass floors.

  • 100% on time at Heat To setting -1.5°F
  • 50% on time at Heat To setting
  • 0% on time at Heat To setting + 1.5°F

Room Sensor and Averaging
The room temperature can be measured using a combination of the built-in and auxiliary sensors.

  • Built-in room sensor only
  • Built-in room sensor with auxiliary room sensor(s) (temperature is averaged)
  • Auxiliary room sensor only

Floor Sensor for Radiant Floor Heating
If a floor sensor is connected, floor minimum and maximum settings are available.
For a combination of air and floor temperature control, leave the internal air sensor on in the setup menu. A floor minimum can be used to prevent a fast drop in temperature caused by receding solar exposure. This operation is recommended for areas heated by afternoon sun through large windows. When the sun sets, 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.
A floor maximum is recommended for rooms with hardwood floors. Setting floor minimum and maximum temperatures is a way of enhancing the comfort of the living space while protecting floor coverings.
If there are more than one floor temperature sensors, the temperature is averaged.
Warm Weather Shut Down (WWSD)
The heating system can automatically shut off based upon the outdoor temperature and the WWSD setting. This provides a convenient way to shut off radiant floor heating. The WWSD feature requires the installation of an Outdoor Sensor 070.

Error Messages
Error icon will appear on the home screen when an error is present.
Description
MEMORY ERROR
The thermostat memory settings are corrupted. To clear, load the factory defaults in the Toolbox menu. The thermostat will not operate any heating equipment while this error message is present.
INTERNAL ROOM SENSOR FAULT
Due to an open or short circuit, the thermostat is unable to read the internal room temperature sensor. If sensor 1 or 2 is set to room the thermostat continues to operate, otherwise operation stops. The error cannot be field repaired. Contact your tekmar sales representative for warranty or repair procedures.
SENSOR 1 FAULT
Due to an open or short circuit, the thermostat is unable to read the sensor wired to S1 and Com. The thermostat stops normal operation if sensor 1 is the only active room or floor sensor or if a floor maximum temperature has been set.
Check the auxiliary sensor wire for short circuits according to the sensor installation manual. It may be necessary to replace the auxiliary sensor. Once the error has been corrected, the error message automatically clears.
SENSOR 2 FAULT
Due to an open or short circuit, the thermostat is unable to read the sensor wired to S2 and Com. The thermostat stops normal operation if sensor 2 is the only active room or floor sensor or if a floor maximum temperature has been set.
Check the auxiliary sensor wire for short circuits according to the sensor installation manual. It may be necessary to replace the auxiliary sensor. Once the error has been corrected, the error message automatically clears.
ROOM HOT WARNING
The room temperature is above the Room Hot Warning setting in the Alerts menu. The warning will automatically clear once the room temperature falls below the setting.
ROOM COLD WARNING
The room temperature is below the Room Cold Warning setting in the Alerts menu. The warning will automatically clear once the room temperature rises above the setting.
