This sensor efficiently signals when the ambient temperature approaches the freeze threshold, and triggers freeze alerts. The connection kit, available for your building/irrigation management system (BMS/IMS), further enhances the convenience of this feature.

The Tekmar 553 TekmarNet Thermostat 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 with the Tekmar 553 Thermostat 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 in the Tekmar 553. The large touchscreen allows you to easily adjust 7 day programmable schedules and room temperature to optimize comfort and energy savings. The Tekmar 553 Thermostat can connect to TekmarNet controls using two or four wires or it can operate as a stand-alone device. Please be aware that the 553 does not have any dry contacts / relay for the second stage like the 545 had if that is what your replacing.
