When mains voltage external controls are used, remove the
MAINS VOLTAGE HEATING CONTROLS CONNECTION PLUG
from the fittings pack and install on the control interface PCB
as follows.
Gain access to the control interface by unclipping the fascia
panel and hinging forward, see diagram 11.3.
Route the external heating controls cable (not supplied) and
connect to the plug
, see diagram 11.3.
Insert plug onto controls interface PCB, see diagram 11.3.
Close the fascia panel and remove the screws to open the rear
cover of control panel, see diagram 11.1.
Secure the external heating control cable in the strain relief, and
thread the cable through rear of the control panel and out of the
cables exit, see diagram 11.4.
Close and secure rear cover of control panel.
IMPORTANT: Remove the wire link from the voltage free
heating controls connector terminal, see diagram 11.1.
Connect external heating controls as diagram 11.5.
External controls should be fitted in accordance with the rules
in force.
11.4 Electrical Connections - Testing
Carry out preliminary electrical system checks as below:
1. Test insulation resistance to earth of mains cables.
2. Test the earth continuity and short circuit of cables.
3. Test the polarity of the mains.
