Mounting and installation

The thermostat can be mounted on a recessed square 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.

Please also refer to the Mounting Instructions M3066… enclosed with the thermostat.

·

  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, Y11, Y12)

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.

·

  The AC 230 V mains supply line must have an external circuit breaker with a rated

current of no more than 10 A.

·

  Only valves rated for AC 230 V may be used.

·

  Disconnect from supply before opening the cover

After applying power, the thermostat makes a reset during which all LCD segments
flash, indicating that the reset has been correctly made. This takes about 3 seconds.
Then, 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 (please also refer to “

Parameter settings

”).

·

  Set the heating/cooling mode via parameter P22 depending on the application.

Factory setting is “Manual heat/cool changeover”. Set P22 accordingly in ”Cooling
only” or “Heating only” mode.

·

  When the room temperature displays on the thermostat does not match the room

temperature effectively measured, you can recalibrate the temperature sensor via
parameter P07.

·

  For comfort and energy saving reasons, it is suggested to review the setpoints and

setpoint ranges (parameters P03…P06), if necessary, to change them accordingly.

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.
