10.4 Boiler Operation

Domestic hot water supply always takes priority over central

heating.
Demand for hot water required during central heating period,

boiler automatically switches to hot water mode until demand

is satisfied i.e. storage water is to required temperature.

This interruption in central heating is only when demand for

hot water is present and should not be noticed by the User.

10.5 Central Heating Mode

Call for heat. Pump will start to circulate central heating

water, operating the flow switch.

Fan will run. Once fan speed is reached burner will light.

Burner output automatically adjusts to suit system

demand; as temperature of water in boiler approaches

that set by adjustable temperature selector, burner output

is reduced.

When set temperature is reached, burner is turned off

and fan stops. Pump continues to run for three minutes

to remove residual heat build up in boiler. Burner will not

relight for 3 minutes.

If CH sensor has not registered pre-set temperature but

room thermostat is satisfied the burner is turned off. Fan

stops. Pump continues to run for three minutes. In this

instance there is no 3 minute delay before burner relights.

If there is demand for DHW during 3 minute burner delay,

boiler will operate to provide DHW until tap is closed.

Boiler will immediately revert to provide CH if there is

demand.

10.6 Domestic Hot Water Mode

• Flow switch senses demand for hot water (opening a hot

water tap, etc.), the pump starts and burner lights at its

ignition output, increasing to its maximum output.

• Water in the boiler is diverted from central heating

system to domestic hot water heat exchanger, heating the

incoming supply water.

• Burner output is varied to maintain temperature of hot

water as set by the adjustable temperature selector.

•

When flow switch senses hot water is no longer required

burner is turned off. Boiler immediately returns to central

heating mode.

10 - OPERATING INSTRUCTIONS

10.7 Frost Protection

Boiler has a built in frost thermostat which automatically turns

boiler and pump on.
If water in boiler falls below 41°F (5°C), providing the display

is switched on, boiler will operate until water temperature in

the system reaches approximately 86°F (30°C).
Frost protection is for the boiler only and not for complete

Central Heating System.

10.8 Pump

If display is switched on and boiler has not operated for 24

hours for heating or hot water, pump will operate automatically

for five minutes every 24 hours.

10.9 Low Water Pressure Sensor (Internal)

This device protects the primary exchanger from damage. It will

not allow the boiler to run in a LOW water pressure situation. Low

water condition occurs when water pressure drops below 7.0 psi

(0.5 bar), approximately.
