Mounting and installation
The room controller can be mounted on a recessed rectangular conduit box with
fixing centres of 60.3 mm. The mounting location on a wall should not be in niches
or bookshelves, not behind curtains, above or near heat sources and wind outlet or
inlet, and not exposed to direct solar radiation. Mounting height is about 1.5 m
above the floor.
You can also refer to the Mounting Instructions M3064 enclosed with the controller.
•
Wiring, fuse and earthing must be installed in compliance with local regulations.
•
The cables to the controller, fan and valves carry AC 230 V mains voltage and
must be appropriate sized.
•
Only valves rated for AC 230 V may be used.
•
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.
•
No metal conduits.
•
No cables provided with a metal sheath.
•
Disconnect from supply before opening the cover.
After applying power, the controller makes a reset during which all LCD segments
displayed, indicating that the reset has been correctly made. This takes about 3
seconds. Then, the controller is ready for commissioning by qualified HVAC staff.
The control parameters of the controller can be set to ensure optimum performance
of the entire system (please refer to
“
Parameter Settings
”
).
•
Depending on the application, the Heat/Cool mode must be set via parameter
P22. Factory setting is
“
Manual Heat/Cool changeover
”
. When using in
“
Cooling
only
”
or
“
Heating only
”
, P22 must be set accordingly.
•
If the room temperature displayed by the controller does not accord with the
room temperature effectively measured, the temperature sensor can be recali-
brated. In that case, parameter P07 must be changed.
•
For comfort and energy saving reasons, it is suggested to review the setpoints
and setpoint ranges (parameters P03
…
P06) and, if necessary, to change them
accordingly
