3. INITIAL LIGHTING
If turning on the boiler for the first time carry out the following steps:
Check that the electrical supply to the boiler is ON at the
external isolator.
Ensure all hot taps are closed.
Set any remote controls as required.
Turn the CH and DHW controls to the minimum setting. Switch on
the appliance at the on/off switch on the control panel. The boiler
will then be in the STANDBY mode.
Check the heating system pressure displayed in the RH lower
corner of the display. This should read at least 1.0 bar. A sealed
pressurised system must be filled by a competent person.
Only operate the boiler when you are sure that the system has been filled
and pressurised. If you are in any doubt about the boiler being filled with
water contact your installer.
4. OPERATION OF CENTRAL HEATING
In order to turn on the central heating and adjust the temperature, turn the
control knob P1 to the desired setting between off and max 82°C.
When the control knob is turned the central heating water temperature will
flash and indicate the new temperature setting.
After a delay of 5 seconds the display will revert to a steady display of actual
central heating water temperature. This will disappear if there is no central
heating demand.
During a central heating demand the radiator symbol and the central heating
water temperature will be illuminated on the display.
If central heating is not required for any extended period turn the control
knob P1 fully anti-clockwise to the off position. In this position the “heating
off “ symbol will be displayed, the domestic hot water and frost protection
will still be active. This is also the “summer mode”.
5. OPERATION OF DOMESTIC HOT WATER
The domestic hot water temperature is adjustable between 30°C and 65°C
by the control knob P2.
When the control knob is turned the DHW water temperature will flash and
indicate the new temperature setting.
After a delay of 5 seconds the display will revert to a steady display of actual
DHW temperature. This will disappear if there is no DHW demand.
During a DHW demand, the tap symbol and the DHW temperature will be
illuminated on the display.
6. PRE-HEAT BUTTON
With the pre-heat button selected the boiler is maintained in a hot condition
to enable a fast response to any DHW demand. When selected, PRE-HEAT
will be illuminated on the display.
If required this can be selected for all year round use, but will be of
maximum benefit in the summer months, or when there is little or no
demand for central heating, in which case the boiler would become cold
without the pre-heat button selected.
The pre-heat function has a built-in intelligent function that will turn itself off
if there is no DHW demand for a 24 hour period. If previously selected, once
DHW water has been drawn off, the function will automatically re-enable.
