2.4 End of useful life

Consult your supplier as to what you should do with the ComfoControl at the end of its useful life. If the ComfoControl cannot be returned to the supplier, avoid disposing of it with the industrial waste, and ask your local council about the options for recycling the components or processing the materials in an environmentally friendly manner.

3 For the Fitter

This chapter describes how to fit the ComfoControl.

3.1 Installation conditions

In order to determine whether the ComfoControl can be installed in a certain area, the following aspects must be taken into account:

• The ComfoControl must be mounted 1.5 metres from the floor.
• The ComfoControl must be fitted to allow sufficient air to circulate. For example, not behind a cupboard, or in a corner.
• The ComfoControl must not be located close to a heat source, such as radiators, TVs, lamps, etc. Direct sunlight must also be avoided.
• The ComfoControl must not be located close to a cold source, such as cold-water pipes or unheated walls (due to poorly heated areas on the other side of the wall), etc.
• The following facilities must be available in the living area concerned:

- Flush-fit casing for the ComfoControl.

• 12V DC power supply from the ventilation system.
• A/B communication cable from the ventilation system.

3.2. Installing ComfoControl

3.2.1 Transport and unpacking

• Take care when transporting and unpacking the ComfoControl.

Make sure the packing material is disposed of in an environmentally friendly manner.

3.2.2 Checking the delivery

Contact your supplier immediately in case of damage or an incomplete delivery. The delivery includes:

• ComfoControl.
• Mounting bracket (fitted to the bottom of the Comfo-Control).
• Connectors (fitted to the rear of the ComfoControl on the PCB).
• User manual.

3.3 Wall mounting

- Mount the bracket on the wall.

Technical diagram showing a mechanical assembly with red arrows indicating direction and a grid of four cells below.

The bracket has fi ve mounting holes.

If required, the bracket can be fitted 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 connector.

The wiring diagram can be found at the rear of the ComfoControl:

• Plug the connector into the 12V DC "POWER" fitting on the PCB.
• Plug the connector into the RS 485 "COMM" fitting on the PCB.

Open Comm Power Relay								Relay Temp.Sens

The cable specification is: 4 x 0.25 mm ^2 protected (twisted pair).

3.5 Connection to external temperature sensor

- Connect the temperature sensor cable to the connector.

The wiring diagram can be found at the rear of the ComfoControl:

• Plug the connector into the "TEMP.SENS" fitting on the PCB.
  • Fit both jumpers to the PCB at position 1:2 (left).

Jumpers Left: Temp. Senso Jumpers Right: Relay 2
Open Comm Power Relay Relay Temp. Sens

*	*	A	B	-	+	*	*	-	+

The temperature sensor specification is: NTC 10 KΩ (optional).

The external temperature sensor is optional. The indoor temperature is usually monitored by an internal temperature sensor (in the ComfoControl). However, indoor temperature can also be monitored using an external temperature sensor. This may be because the ComfoControl is to be fitted 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 temperature sensor connected to the PCB in the back of the ComfoControl provides a solution to these problems.

3.6 Commissioning the ventilation and cooling system

Once fitted, 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 ventilation and/or cooling system.
