Use
Room temperature control (heating or cooling) in individual rooms and zones by
means of:
•
2-pipe fan coil units
•
2-pipe fan coil units with electrical heater
•
4-pipe fan coil units
•
Chilled /heated ceiling
•
Chilled /heated ceiling and electrical heater
•
Chilled ceiling and radiator / under floor heating
•
Compressors in DX-type equipment
•
Compressors in DX-type equipment with electrical heater
The RDF800KN... controls:
•
One single or 3-speed fan
•
One or two 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
Used in systems with:
•
Heating or cooling mode
•
Automatic heating/cooling changeover
•
Manual heating/cooling changeover
•
Heating and cooling mode (such as 4-pipe system)
The room thermostats are delivered with a fixed set of applications. The relevant
application is selected and activated during commissioning using one of the
following tools:
•
Synco ACS
•
ETS4
•
Local DIP switch and HMI
Functions
•
Room temperature control via built-in temperature sensor or external room
temperature / return air temperature sensor
•
Changeover between heating and cooling mode (automatically via local sensor
or bus, or manually)
•
Selection of applications via DIP switches or commissioning tool
•
Selection of operating mode via touch screen
•
Temporary Comfort mode extension
•
1- or 3-speed fan control (automatically or manually)
•
Display of current room temperature or setpoint in °C and/or °F
•
Minimum and maximum limitation of room temperature setpoint
•
Keylock function: unlock, total lock and setpoint
•
2 multifunctional inputs, freely selectable for:
−
Window contact
−
Presence detector
−
External room temperature or return air temperature sensor
−
Fault input
−
Monitor input for temperature sensor or switch state
−
Sensor for automatic heating / cooling changeover (RDF…)
−
Dew point sensor (RDF…)
−
Electric heater enable (RDF…)
•
Advanced fan control function, such as: fan kick, fan start delay, and selectable
fan operation (enable, disable or depending on heating or cooling mode)
