Page 10: Sequence Of Operation
Sequence of Operation Heating Operation The heating setpoint can be set from 40 to 95°F (4.5 to 35°C). 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. The W2 relay turns on based on settings selected in the Setup menu. W2 turns off when the air temperature is 0.5°F (0.25°C) below the Heat To setting. 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 thermostat can measure room temperature between -46 to 212°F (-43 to 100°C). 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... -

Page 21: Error Messages
Error Messages When an error occurs an email notification will be sent to the registered tekmar Connect mobile or web app account owner. 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 or cooling 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 installa- tion 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 installa- tion 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. -
