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 ins tallation
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.
· 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.
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
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).
After powerfail the thermostat restarts in the same mode as before.

· 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.
· 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.
· 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.
We recommend to review the setpoints and setpoint ranges (parameters P08…P12)
and change 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.
