Dual Fuel Dual fuel systems include a heat pump together with a backup heat source such as a furnace or a hydronic fan coil. When Dual Fuel is set to on, the heat pump (relays Y1 and Y2) is shut off whenever the backup heating equipment (relays W1 and W2) is operating.

HIGH HUMIDITY WARNING The relative humidity is above the High Humidity Warning setting in the Alerts menu. The warning will automatically clear once the relative humidity falls below the setting.

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 is more than one-floor temperature sensor, the temperature is averaged.

CHANGE UV LAMP WARNING The UV lamp run time has exceeded the UV Lamp setting in the Alerts menu and requires replacement. To clear the warning, press the UV Lamp Replaced button.

SENSOR 3 FAULT Due to an open or short circuit, the thermostat is unable to read the sensor wired to S3 and Com. The thermostat stops normal operation if sensor 3 is the only active room 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.

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.

Humidifier Operation The thermostat controls the relative humidity (RH) by operating either the Accessory 1 or Accessory 2 relays. This is an installer configurable setting. When the RH is below the Humidify To setting by 3%, the Accessory 1 or 2 relays are closed to operate a humidifier. The humidifier is shut off when the RH reaches the Humidify To setting.

Conventional Systems A conventional heating system includes furnaces, air conditioners, hydronic heating systems with baseboards, radiant floors, or fan coils, and electric heating. The thermostat supports up to two heating stages, two cooling stages, a fan, and two accessory relays.

Heat Pump Loop Valve Operation The thermostat supports water-to-air heat pump systems that absorb or reject heat to a hydronic building loop. Whenever the heat pump compressor Y1 or Y2 relay is turned on, the Accessory 1 relay closes to open a hydronic zone valve. This allows variable-speed pumps on the hydronic loop to operate at lower speeds when the heat pump is off, thereby saving electrical energy.

Incorrectly setting the time and date manually may prevent the thermostat from communicating with the mobile app. An automatic time source is recommended when using an Internet connection.

Heat Pump Balance Point An air source heat pump’s Coefficient of Performance (COP) declines with falling outdoor air temperature. The Balance Point is the outdoor temperature at which it is more economical to shut off the heat pump (relays Y1 and Y2) and operate the backup heating equipment (relays W1 and W2).
