IMPORTANT SAFETY ADVICE

Always disconnect the supply before working on the Heater.

This product should be mounted safely onto a suitable wall.

The Control Panel may only be operated when mounted horizontally

on a wall.

The Control Panel should not be installed in a toilet or washroom.

The Control Panel is not suitable for ceiling mounting.

Ensure that cables are of adequate current carrying capacity.

WARNING: Isolate electrical supply to ALL modular linked units

when carrying out maintenance.

General

The CFCH control panel is an electronic controller for use with the electronic

range of Dimplex Heaters. This control panel has a number of integrated

features such as, heat selection, timer, programming and frost protection.

Connectivity between heater and control panel is achieved using LAN

(Local Area Network) cable i.e. CAT5, CAT5E or CAT6, pin configuration is

straight through 1 to 1. This eases installation and improves reliability

considerably.

Electrical Connection - see Fig. 2.

The control panel must be supplied at terminal block ‘a’ with a ~230-240V

supply. The cable clamp ‘d’ is provided to ensure the mains cable ’f’ (at

least 2G x 0.75mm²) is secure. The LAN cable connecting the heater to the

control panel is fed to socket ‘c’ in a similar way to the power cable.

Note: The control panel should be protected by a suitable fuse.

Installation

The control panel should be mounted in a convenient location away from

direct sun light or draughty areas.

Surface Mounting

The control panel can be directly mounted onto a suitable wall. This is

done by removing the back cover and using it as a guide to mark off the

holes - see Fig. 3. Drill and plug the holes with suitable wall plugs. Remove

one of the knockouts on either the top or the bottom to allow entry for the

supply cables via surface trunking. Mount the back cover to the wall and

feed supply cables through the trunking and into the back cover. Make the

appropriate electrical and control connections to the PCB as discussed in

the Electrical Connection section. Clip the front cover on and secure with

the two screws provided in the direction shown in Fig. 2. Turn on the supply

and check the control functions.

Surface Mounting to a Recessed Box

The control panel can also be mounted onto standard single gang and

double gang backing boxes. The backing box (not supplied) should be

already recessed into the wall. Remove the large knock-out in the back

cover (see ‘e’ in Fig. 2) and secure it onto the backing box using the holes

provided - see Fig. 3. Feed the supply cables through the recessed conduit

into the recessed box and out into the back cover. Make the appropriate

electrical and control connections as discussed in the Electrical Connection

section. Clip the front cover on and secure with the two screws provided in

the direction shown in Fig. 2. Turn on the supply and check the control

functions.

Control Panel Power-up

When the controller is powered up for the first time, it will check if there are

heaters connected and that they are operational. When this check is

completed, an LED will light beside the screen (see Fig. 1) to show that the

system is functioning. If the LED does not light, check the following;

(1) The control panel is supplied with electrical power.

(2) The heater is supplied with electrical power.

(3) The LAN connection between the controller and the heater is working.

NOTE : The controller will also perform this check after a power cut.
