Dimplex Industrial Fan Heater
Electronic Control Panel : CFCH
IMPORTANT: THESE INSTRUCTIONS SHOULD BE READ CAREFULLY AND RETAINED FOR FUTURE REFERENCE
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.
