•
Note the requirements regarding ambient temperature and
the permissible relative humidity.
•
Make sure the regulator cannot get splashed.
2.2.2 Mounting the Celcia MC4
The regulator is mounted using three screws. The top screw
is to hang the regulator on and cannot be tightened once the
regulator has been mounted. The bottom screws (behind the
small cover) are to hold it firmly in place.
Mount the regulator as follows:
•
Determine the position of the regulator and press the drill-
ing template against the wall.
•
Drill the three holes (Ø 5 mm) as indicated by the tem-
plate.
•
Insert the plugs.
•
Screw the top screw into the plug and mount the regulator
without any play.
•
Remove the small cover from the regulator to make the
lower slots accessible.
•
Screw the bottom two screws into the plugs.
•
Straighten the regulator and tighten these two screws.
•
Replace the cover.
2.2.3 Guidelines for connecting the sensors and wiring
the system components
•
Mount the regulator as close as possible to the system
components to be controlled (check maximum cable
lengths for OpenTherm connections and sensors)
•
An earth terminal has been fitted next to the connection
for the mains lead. Always connect this in order to comply
with the safety regulations.
•
Always connect the mains supply to an earthed wall
socket.
•
Use double insulated wiring for the exit relays that switch
a power supply with no earth connection..
•
Fit a strain relief to all cable connections.
r
Looping the supply voltage and/or earth to e.g. a pump, is not
allowed.
2.2.4 Connecting the sensors and wiring the system
components
Connect temperature sensors, thermostats, boilers and other
wiring as follows:
