TEKMAR 521 PROGRAMMABLE THERMOSTAT - TWO HEAT OR ONE HEAT & ONE COOL - INCLUDES 079 SENSOR

The Tekmar 521 Programmable Thermostat is designed for three different modes of operation - single stage heating - two stages of heating with a fan or one stage of heating and one stage of cooling with a fan. Two auxiliary sensors may be added to the Tekmar 521 thermostat to measure the floor outdoor or room temperature. A Tekmar 079 Slab Sensor is included to measure floor temperature to protect the floor from overheating and enhance comfort. The programmable schedule supports either a 7 day or 24 hour schedule with 2 or 4 events per day. A permanent temperature hold button overrides the programmable schedule. An optional Tekmar 012 Adaptor Plate is available to allow the thermostat to mount onto a single gang electrical box.
