Description for Tekmar 553

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.

The Tekmar 553 Thermostat Rocks!

        Comments about tekmarNet Thermostat - Two Stage Heat, One Stage Cool, Fan:

        I replaced my Tekmar 543 two stage thermostat with the 553 and now I have complete control over first stage radiant floor heat and my second stage hydrocoil heating system. The 543 didn't provide any user control over second stage heating but the 553 lets you set first stage run time and set point differential to determine when the second stage kicks in.

        I do wish they offered this thermostat with only two heating stages and no cooling control. Most high efficiency air conditioners are two stage and have their own proprietary communicating thermostats to take advantage of all of their features.
