Innovative hydronic heating zone and Pulse Width Modulation technology is used in the Thermostat 518. The thermostat automatically detects a single auxiliary sensor to measure either outdoor, floor or remote room temperature. Simply use the buttons to change the temperature in an up or down motion and the display is large type and easy to read. This easy to install thermostat is a direct replacement for tekmar Control Systems Thermostats 507 and 508.
