Wall mounting

• Mount the bracket on the wall.
The bracket has fi ve mounting holes.
If required, the bracket can be fi tted to the fl ush-
fi t casing.
• Connect the ComfoControl to the ventilation system;
see § 3.4.
• Slide the ComfoControl onto the mounting bracket.
• Fasten the bottom of the ComfoControl with a screw.
3.4 Connection to
ventilation system
• Connect the 12V DC cable to the connector.
• Connect the A/B communication cable to the con-
nector.
The wiring diagram can be found at the rear of the Com-
foControl:
• Plug the connector into the 12V DC "POWER" fi tting
on the PCB.
• Plug the connector into the RS 485 "COMM" fi tting on
the PCB.

3.5 Connection to external
temperature sensor
• Connect the temperature sensor cable to the connec-
tor.
The wiring diagram can be found at the rear of the Com-
foControl:
• Plug the connector into the "TEMP.SENS" fi tting on
the PCB.
• Fit both jumpers to the PCB at position 1:2 (left).

The temperature sensor specifi cation is: NTC 10
KΩ (optional).
The external temperature sensor is optional. The indoor
temperature is usually monitored by an internal tempera-
ture sensor (in the ComfoControl). However, indoor tem-
perature can also be monitored using an external tem-
perature sensor. This may be because the ComfoControl
is to be fi tted in a different location than the one to be
monitored, for example in the hall. It is also possible that
variables in the vicinity of the unit (e.g. wall temperature)
could affect temperature readings. An external tempera-
ture sensor connected to the PCB in the back of the Com-
foControl provides a solution to these problems.
3.6 Commissioning the ventilation
and cooling system
2
Once fi tted, the ventilation and cooling system must be
*
commissioned.
This can be done via the P menus of the ComfoControl.
These P menus can be used to enter various settings (and
programmes) for the ventilation and cooling system. An
overview of the available P menus is given below:
For a list of available settings in the P (sub)menus,
please refer to the user manual for your ventila-
tion and/or cooling system.
