Hi Replaced the actuator on the zone valve, but this has created a new fault. Central heating circulation is good, all radiators are hot. However the only way I can control the heating is via the room stat and not the time clock. When the time clock is off, but the room stat is at high...

its a gloworm 40FF. The pump doesn't seem to work on overun.

ok, will do. Out of interest whats the purpose of the bypass pipe?

have taken the head off the valve and it turns easily by 20d, and going replace 2 port valve next week. Thanks for your help with the fault diagnosis, hopefully this will solve the problem. Thanks again.

Hi, sorry don't have a volt meter but have been doing some more investigation. When the HW and CH are switched on at the same time, and I manually operate the CH 2 port valve the CH throughout the house gets hot. As soon as the HW turns off either from thermostat in cylinder or timer the CH...

the pipes cool down when the CH is on and the HW is off.

just checked the valve again. The lever is loose when on and stiff when off. The room stat turns the boiler off immediately when on low, but doesn't turn it on immediately when turned to high, but comes on eventually after around ten minutes. Have removed the honeywell valve head and, and...

hi, moving the stat up or down doesn't make any difference to the valve lever.

the hot water is a drayton 2 port valve and the CH is a honeywell 2 port valve

The pump is separate. I have moved the pump from setting 2 to 3 to see if that works and closed off all of the radiators downstairs. When the central heating and hot water are on at the same time the boiler doesn't shut down, but only heats the hot water. Radiators are still only luke warm.

Hi The radiators in my house are only getting warm at the top. Bled all of the radiators and therefore don't think that its air in the system. Hot water is working fine. Boiler starts up for about 3-5 minutes and then shuts down. Pump is working fine. Thermostat is at the max. Think it...
