Site requirements
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 - Marked “COOKER”
Channel 2 - supplies hot water - Marked “BOILER”
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
switch should be set to operate at a temperature of
approximately 4˚C.
Consideration must be given when selecting 3 port mid-
position or 2 port zone valves.
It is essential that the capacity of the individual valves is
considered to enable the correct size to be chosen.
For this range of appliance, where Honeywell valves are
selected, a guide to selection is as follows:_
Model:-
460K, 22mm (3/4”) 2 or 3 port
480K, 28mm (1”) 2 or 3 port
499K, 28mm (1”) 2 port only
3 Port Mid Position valves are inappropriate for selection
with the 499K model.
