Worc Greenstar with central heating problem.
Boiler heats tap hot water no problems.
However central heating is irratic. When I looked at the boiler
is was cruising at 34 degrees even though the central heating was set
on and there is no wall thermostat.
I turned up the central heating temperature a little to the 3 or 4 position the boiler then fired heating on a low setting until about 42 degree then shutdown again?
I turned up the central heating temperature to the E setting which should be about 75 degrees the boiler then started very slowly heating up doing this -|- cross symbol. Every so often. This seems to indicate a trap filling program was active? Even after about 10 minutes it had only got to about 50 degrees.
What is this boiler doing? Any ideas as to the problem?
