Applications
Room temperature control in individual rooms and zones:
● Heated or cooled with 2-pipe fan coil units
● Heated or cooled with 2-pipe fan coil units with electrical heater
● Heated and cooled with 4-pipe fan coil units
The room thermostat controls:
● One ECM fan
● One or two on/off valve actuators
● One on/off valve actuator and one 1-stage electric heater
● One 3-position valve actuator
● One 1-stage compressor with electric heater
Used in systems with:
● Heating or cooling
● Automatic heating/cooling changeover
● Manual heating/cooling changeover
● Heating and cooling (e.g. 4-pipe system)
Functions
