A minimum of 20 gauge thermostat wire is recommended. Intended for use with a 12VDC power supply that does not exceed 2 amps. 

Equipped with a self-resetting PTC fuse located in the thermostat. The fuse is designed to "open" if the circuit is mis-wired or if there is a short in the system. If the PTC fuse continues to "open", the fault must be located and corrected. 

An internal temperature sensor on the thermostat can act as the room temperature sensor. Alternatively, a remote temperature sensor can be connected and mounted virtually anywhere. Remote sensors are available separately.
