3.0 Appliance Operation

3.1

Operating Mode (Fig. 2)

1. With a demand for heating or hot water, the pump

circulates water through the primary circuit. If the pressure is

at least 0.5 bar and the ignition sequence will start.

2. When the flow temperature exceeds the setting

temperature, a 3 minute delay occurs before the burner

relights automatically (anti-cycling). The pump continues to

run during this period.

3. When the demand is satisfied the burner is extinguished

and the pump continues to run for a period of 3 minutes

(Pump Overrun).

IMPORTANT: When the selector switch is in the ‘0’

(Off) position the electrical supply to the boiler is

isolated. The boiler will not operate.

3.2

Frost Protection Mode

1. The frost protection mode is integral to the appliance and

functions when the selector switch (see Section 2.1) is in the

ON position ( ). If the system temperature falls below

5° C then the boiler will fire on its minimum setting until a

flow temperature of 30° C is reached. Further protection

can be incorporated by using a system frost thermostat.

3.3

Pump Protection

1. With the selector switch (see Section 2.1) in the ON

position ( ) the pump will automatically operate for 1

minute in every 24 hours to prevent sticking.
