This brochure will provide you with the information you need to benefit the most from your tekmarNet® thermostat. Please visit www.tekmarcontrols.com for more detailed information on this or any other tekmar product.

This thermostat provides heating for one zone in your building. It will maintain your air temperature with an on board ROOM sensor, but may also have an auxiliary ROOM, FLOOR, or OUTDOOR sensor attached. A ROOM sensor will allow control of a location other than the one in which the thermostat is installed. An outdoor sensor will allow this and all other tekmarNet® thermostats in your building to display the outdoor temperature on their displays. A floor sensor will allow this thermostat to control your floor temperature. This thermostat can maintain floor temperature only, air temperature only, or floor and air temperature together.

With the addition of one of tekmar’s energy saving accessories, this thermostat can also lower its temperature setting at night or when you are away from the house.
