OPERATING THE APPLIANCE

SWITCHING THE APPLIANCE ON/OFF

Switching on

Switch on the appliance at the master switch (I).

The indicator lamp shows green and the display will show the central heating flow temperature, when the appliance is operating in the central heating mode.

Note: If the display alternates between -II- & the central heating flow temperature, the condensate trap filling programme is active. If the display shows “t” the tank heat up programme is running.

The condensate trap filling programme ensures that the condensate trap is filled after the appliance has been installed or after the appliance has been out of use for a long period. For that reason, the appliance remains at minimum heating output for approximately 15 minutes.

Switching off

Switch off the appliance at the master switch (0).

The green indicator lamp goes out. The display on the optional timer (if fitted) will continue to operate until the battery back-up is exhausted.

SETTING THE CENTRAL HEATING TEMPERATURE

Turn the central heating temperature control to the desired level:

Control Setting	Water Temperature
Anti-clockwise limit	approx. 35°C
'E'	approx. 75°C
Clockwise limit	approx. 88°C

When the burner is lit, the red indicator lamp is illuminated.

CONTROLLING CENTRAL HEATING

Set the timer (if fitted) to the correct time.

Set room thermostat to the desired room temperature.

Set temperature driven control unit, if fitted. Refer to the instructions with the control.

Set the thermostatic radiator valves to the desired settings.
