RAA21 Electromechanical room thermostat
AC thermostat RAA21 Description:
The RAA21 room thermostat is used to keep the room at the temperature you choose in systems that only heat or cool.
The RAA21 is a 24-240 volt room thermostat used in heating or cooling applications to sustain the selected room temperature. Its range is from 8-30 degrees Centigrade.
The RAA21 room thermostat has two distinct outputs, one for heating and the other for cooling. If the temperature in the room decreases below the setpoint, the heating contact will close. If the temperature in the chamber exceeds the setpoint, the cooling contact will close.
