BOILER CONTROLS
BOILER CONTROL THERMOSTAT
The temperature of the water within the boiler is controlled and maintained by the
Boiler Control
Thermostat
located on the boiler control panel.
TEMPERATURE SETTINGS:
The Boiler Control Thermostat has a range of 50°C to 80°C. The recommended setting for the boiler
control thermostat is:
WINTER Heating and hot water supply 80°C
SUMMER Domestic hot water supply 65°C
It is not recommended to operate the boiler with a thermostat setting of less than 60°C as this will
precipitate corrosion, thus reducing the life of the boiler.
HIGH LIMIT STAT
The high limit lockout will occur when the water within the boiler is or has overheated e.g. reached a
temperature above that set on the high limit thermostat.
TO RESET THE BOILER
When the boiler has had time to cool, unscrew black cap and press button on the control panel to
reset.
LOCKOUT INDICATOR: RED
The lock out indicator will illuminate when the burner has failed to fire, e.g. No fuel or an electrical
fault. Wait for two minutes then press the manual reset button (coloured red – Fig 1) on the control
box to reset.
