You may opt to have a programmer sited away from the boil-
er, in which case your installer will provide setting and operating

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 horizon-
tal bar, and the control knob can be set anywhere between this
and the maximum temperature, which is indicated by five hori-
zontal 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
central heating control thermostat (described above). A high set-
ting 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.
