Mounting and installation
Mount the room controller 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.
·
Properly size the cables to the controller, fan and valve actuators for AC 230 V
mains voltage
·
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
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.
·
No metal conduits
·
No cables provided with a metal sheath
·
Disconnect from supply before opening the cover
Set the controller application via the DIP switches before snapping the front panel
on the mounting base.
After power is applied, the controller 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 controller is ready for commissioning by qualified HVAC staff.
