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. The basic TX400 can be used as a heating only, cooling only, or zone system thermostat depending on how the subbase is wired (see schematic diagrams below). The TX400, when employed with the DA490 Series, covers all types of heating and cooling systems. See the DA490 Series for switching arrangements and schematics.
