Product Code: TJ-TEK519

Radiant Thermostat, One Stage Heat (Includes Slab Sensor 079)

The Radiant Thermostat 519 accurately controls the room and/or floor temperature for a hydronic heating zone using Pulse Width Modulation (PWM) technology. Simple up and down buttons and a display with large type make this thermostat easy to read and use. A Slab Sensor 079 is included to measure floor temperature to protect the floor from overheating and enhance comfort. This easy to install thermostat is a direct replacement for the tekmar Thermostat 509. An optional Adaptor Plate 012 is available which allows the thermostat to be installed onto a single gang electrical box.
