Internal temperature and time controls are supplied.
These provide control of cooking and hot water
temperatures. The cooker is supplied with 2-channel
programmer:-
Channel 1 - supplies hot water - Marked “BOILER”.
Channel 2 - controls the cooker burner - Marked “COOKER”.
A separate switch in conjunction with the hot water
channel gives priority to either the domestic hot water or
the supply of hot water for central heating/DHW (if
external controls are fitted).
It is recommended that independent temperature
controls are provided for comfortable room temperatures,
for economic operation and for control of the domestic
hot water flow to the cylinder.
Consideration should be given to fitting a frost thermostat
which should be set to operate at a temperature of
approximately 4
˚
C.
Wiring external to the appliance must be installed in
accordance with current National Wiring Regulations and
any local regulations which apply. The appliance is
supplied for 230 Volt ~ 50 Hz and a fuse rating of 3 amps.
The method of connection to the mains supply should
facilitate complete electrical isolation of the appliance, by
the use of a fused double pole switch having a contact
separation of at least 3mm serving only the appliance.
The point of connection to the mains should be readily
accessible and adjacent to the appliance. The installation
should be protected by a 30mA Residual Current Circuit
Breaker (RCCB).
The minimum requirement for the power cable is that it
should be 3 core PVC sheathed flexible cord (85
˚
C min) at
least 0.75mm
2
(24 x 0.2mm) to the relevant standard.
WARNING: THIS APPLIANCE MUST BE EARTHED
In the event of an electrical fault after installation of the
appliance, preliminary electrical system checks must be
carried out i.e. earth continuity, short circuit, polarity and
resistance to earth.
For wiring instructions see wiring diagram.
The circulating pump MUST be connected to PL and PN
on the terminal block (see Fig. 2) and the cables passed
through the grommet in the left hand side panel, at the
front.
