TX400 Series Thermostats

The TX400 is a low voltage wall mounted room temperature controller. The heart of the TX400 thermostat is a SPDT sealed-in-glass switch, hermetically sealed to protect from dust and moisture. This switch does not require the critical leveling necessary with other types of thermostats. A positive action of the switch is obtained by a magnet mounted on the temperature sensing coiled bimetal.
