Building Technologies 2018-12-27
Use
To control the room temperature in individual rooms and zones that are:
· 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
· Heated or cooled with compressor in DX type equipment
· Heated or cooled with compressor in DX type equipment with electrical heater
· Heated and cooled with compressor in DX type equipment
The RDF300… / RDF400… / RDF600... control:
· One 1- or 3-speed fan
· One or 2 on/off valve actuators
· One on/off valve actuator and one 1-stage electrical heater
· One 3-position valve actuator
· One 1-stage compressor in DX type equipment or one 1-stage compressor with
electrical heater
The RDF340… controls:
· One 1- or 3-speed fan
· One or 2 DC 0…10 V valve actuators
· One DC 0…10 V valve actuator and one modulating electrical heater (DC 0…10 V)
Used in systems with:
· Heating or cooling mode
· Automatic heating/cooling changeover
· Manual heating/cooling changeover
· Heating and cooling mode (e.g. 4-pipe system)
Functions
