The tekmarNet® Thermostat 553 is a communicating touchscreen thermostat
designed to operate two heating stages, one cooling stage, a fan and
relative humidity. The heating stages can be hydronic, forced air or a
single stage heat pump. The cooling stage is either an air conditioner or
heat pump. There are two auxiliary sensor inputs available to measure
room, floor, outdoor, coil or duct temperature. The optional floor sensor
allows precise heating of radiant floors by controlling the floor
temperature and maintaining the desired room air temperature. Relative
humidity level can be measured and controlled using the built-in humidity
sensor. The large touchscreen allows you to easily adjust 7-day
programmable schedules and room temperature to optimize comfort and energy
savings. The 553 can connect to tekmarNet ® controls using two or four
wires or it can operate as a stand-alone device.
