TEMP
Low
Setting
The control knob has a range of adjustment as
indicated by the symbols.
EXTERNAL PROGRAMMER
You may opt to have a programmer sited away from the
boiler, in which case your installer will provide setting and
operating instructions.
CENTRAL HEATING TEMPERATURE
CONTROL
The central heating temperature control knob on the boiler
facia panel enables you to control the temperature of the water in
your radiators. A low temperature is indicated by a single
horizontal bar, and the control knob can be set anywhere between
this and the maximum temperature, which is indicated by five
horizontal bars. (As shown in Fig. 1.)
PLEASE NOTE: The control knob must not be set below the
first indicating bar.
HOT WATER TEMPERATURE CONTROL
The hot water control temperature knob on the boiler facia
panel controls the temperature of the primary hot water stored in
the Heatslave tank. The temperature control settings are as for the
High
Setting
central heating control thermostat
(described above). A high setting will give
higher hot water temperatures and greater
quantities of hot water.
The temperature of your hot water
can also be controlled at the tap by varying
the flow rate; increasing the flow rate will
decrease the temperature, and vice versa.
WARNING. Care should be taken when
washing your hands as the combination of
low water flow rate and a high setting of
the hot water control thermostat can result
in very hot water at the tap.
