Mechanical design

The thermostat consists of 2 parts:

Front panel accommodating the electronics, operating elements and built-in room temperature sensor.
Mounting base with the power electronics.

The rear of the mounting base contains the screw terminals Slide the front panel in the mounting base and snap on.

Mounting and installation

Mount the room thermostat on the conduit box. Do not mount on a wall in niches or bookshelves, behind curtains, above or near heat sources, or exposed to direct solar radiation. Mount about 1.5 m above the floor.

Mounting/dismounting

Devices must be mounted on clean, dry indoor place without direct airflow from a heating / cooling device, and not be exposed to dripping or splashing
RDF3… / RDF400…: In case of limited space in the conduit box use the mounting bracket ARG70.3 to increase the headroom by 10mm
Before removing the front cover, disconnect the power supply.

Wiring: See the mounting instructions enclosed with the thermostat:

M3076… for RDF3…, RDF4… ; M3063 for RDF600… .
Wiring, protection and earthing must be installed in compliance with local regulations.

Warning

No internal line protection for supply lines to external consumers (Q1, Q2, Q3, Yxx)
Risk of fire and injury due to short-circuits!

Adapt the line diameters as per local regulations to the rated value of the installed overcurrent protection device.
Use only valve actuators rated for AC 230 V on RDF300… / RDF400… / RDF600..
The AC 230 V mains supply line must have an external fuse or circuit breaker with a rated current of no more than 10 A.
Isolate the cables of SELV inputs X1-M/X2-M if the conduit box carries AC 230 V mains voltage.
Inputs X1-M or X2-M of different units (e.g. summer/winter switch) may be connected in parallel with an external switch. Consider overall maximum contact sensing current for switch rating.
No metal conduits
No cables provided with a metal sheath
Disconnect from supply before opening the cover

Commissioning

Set the thermostat application via the DIP switches before snapping the front panel on the mounting base.
After power is applied, the thermostat carries out a reset during which all LCD segments flash indicating that the reset was correct. After the reset, which takes about 3 seconds, the thermostat is ready for commissioning by qualified HVAC staff.
The control parameters of the thermostat can be set to ensure optimum performance of the entire system (see basic documentation P3076).

Note: After powerfail the thermostat restarts in the same mode as before.

Control sequence: The control sequence may need to be set via parameter P01 depending on the application. The factory setting for the 2-pipe application is “Cooling only”; and “Heating and Cooling” for the 4-pipe application.
Compressor-based application: When the thermostat is used with a compressor, the minimum output on-time (parameter P48) and off-time (parameter P49) for Y11/Y21 must be adjusted to avoid damaging the compressor and shortening its life.
Calibrate sensor: Recalibrate the temperature sensor if the room temperature displayed on the thermostat does not match the room temperature measured (after min. 1 hour of operation). To do this, change parameter P05.
Setpoint and range limitation: We recommend to review the setpoints and setpoint ranges (parameters P08…P12) and changing them as needed to achieve maximum comfort and save energy.

Disposal

The device is considered electrical and electronic equipment for disposal in terms of the applicable European Directive and may not be disposed of as domestic garbage.

Dispose of the device through channels provided for this purpose.
Comply with all local and currently applicable laws and regulations.
