The tekmarNet Thermostat 557 is a communicating touchscreen thermostat designed to operate either a) a hydronic radiant floor with a 2 stage heat pump (water-to-air or air-to-air) for heating and cooling and an emergency backup heating system; or b) 2 stages of heating and 2 stages of cooling. There are 3 auxiliary sensor inputs that can be used to measure room, floor, outdoor, or duct temperature. The optional 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 allows you to easily adjust 7-day programmable schedules and room temperatures to optimize comfort and energy savings. The 557 can connect to tekmarNet controls using 2 or 4 wires or it can be installed as a stand-alone device.
