TEKMAR 557 TEKMARNET THERMOSTAT - TWO STAGE HEAT - TWO COOL - TWO FAN

The Tekmar 557 TekmarNet Thermostat is a communicating touchscreen thermostat designed to operate either a hydronic radiant floor with a two stage heat pump - water-to-air or air-to-air for heating and cooling and an emergency backup heating system or two stages of heating and two stages of cooling. There are three auxiliary sensor inputs on the Tekmar 557 that can be used to measure room floor outdoor or duct temperature. The optional Tekmar 079 floor sensor allows precise heating of radiant floors. Relative humidity level can be measured and controlled using either the built-in or external humidity sensor. The large touchscreen display on the Tekmar 557 allows you to easily adjust 7 day programmable schedules and room temperatures to optimize comfort and energy savings. The Tekmar 557 can connect to TekmarNet controls using two or four wires or it can be installed as a stand-alone device.
