IMPORTANT!
Your boiler must be commissioned in order to:
-
Validate your warranty
-
Ensure the boiler has been installed correctly and avoid premature failure
-
Set the boiler to its optimum efficiency. Operating conditions for the boiler will vary from site to site, your
commissioning engineer has specialised equipment to check the oil pressure and analyse the exhaust gases for
temperature, smoke and carbon dioxide content.
Your installer will organise the commissioning of your boiler. Should you experience any difficulty locating an
engineer, our service department may be able to provide you with details of an engineer in your area.

Boiler Controls – Wallstar Combi
Control Panel
Mixing Valve
The mixing valve can be adjusted to set the maximum temperature of hot water produced. The valve is graduated
between 1 to 5, the greater the number the hotter the water.
IMPORTANT
-
Too high a setting may cause scalding!
Auxiliary Thermostat
This thermostat maintains the temperature of the boiler for the production of hot water. For best hot water
performance leave the knob set in its maximum position.
Heating Thermostat
The heating thermostat regulates the temperature of the water supplied to the central heating system. To achieve the
heating system performance indicated by the ‘max’ setting, the auxiliary thermostat should also be set to its maximum
position.
Note:
The heating function is interrupted whenever there is a demand for domestic hot water.
Boiler Overheat (Limit) Thermostat
In the unlikely event the boiler overheats, the reset button will trip and cut the power supply to the boiler. Allow the
boiler to cool then press the reset button to reset the thermostat.
IMPORTANT
-
If overheating occurs regularly, consult your installation engineer. There may be a fault with the
central heating system.
Note:
Loss of system pressure may cause the overheat (limit) thermostat to trip; refer to the pressure gauge section
below.
Pressure Gauge
The heating system should be pressurised to approximately 1 bar when cold. Check the pressure occasionally, as
loss of pressure may cause the boiler to overheat.
Please refer to the combi fault diagnosis page for instructions
on pressurising the system.

Time Clock Programming Guide
Setting Up
The outer dial should be set to the current time. Rotate the dial slowly in a clockwise direction, until the correct hour is
approaching the arrow printed on the dial.
Manual Switch Operation
The manual switch will provide On / Timed / Off control, thereby allowing manual control of the heating without
disrupting the timed (tappet) settings.
Programming Switching Times
One tappet is equal to 15 minutes. Set the number of tappets to the outer edge of the dial, equal to the duration of
time the heating is required to be switched on.
Power Neon Lamp
The lamp is illuminated when the mains supply to the boiler is switched on.
Limit Neon Lamp
The lamp is illuminated when there is power to the controls, but the boiler has overheated. When the limit reset is
pressed this lamp should extinguish.
Lockout Neon Lamp
The lamp is illuminated when there is power to the controls, but the burner has not fired correctly.
