In normal operation the boiler status display (E) will show the following
codes: 0 – Standby – no demand for heat, C – Central Heating being
supplied, D – DHW being supplied, F – boiler frost protection (boiler fi res
if temperature is below 5°C).
If the pressure is seen to fall below the original installation pressure of
1-2 bar over a period of time then a water leak may be indicated. In this
event conduct the re-pressurising procedure as show on page 4 of the
User Manual.
WINTER OPERATION: COMBI.
1. Ensure gas and electric supplies are available and on
(i.e. card meters are topped up).
2. Ensure boiler thermostat (C) is on and set two thirds of
the way round.
3. Set room thermostat to desired temperature, normally
between 20-23°C.
4. Control individual room via Thermostatic Radiator
Valves. 1 - Low, 2 - Low/Average, 3 - Average,

hours a day. Switch the room thermostat down to 10°C
overnight. This will maintain comfort levels and ensure
the system doesn't freeze.

Questions and answers
Hello why **** I getting heat in radiators upstairs but only slightly aired downstairs esp 35 I have bled radiators I have topped up the pressure
The issue may be due to trapped air, an unbalanced system, or a circulation problem. After bleeding and topping up the pressure, air could still be trapped in the system, preventing proper circulation to the downstairs radiators. Additionally, if the system is unbalanced, more hot water may be flowing to the upstairs radiators. Adjusting the lockshield valves on the upstairs radiators to restrict flow and allow more heat to reach the downstairs radiators may help. If the problem persists, the pump may not be circulating water effectively, or there could be a blockage in the system. Checking the pump operation and ensuring no blockages in the pipework would be the next step.
