Hi What temp should this be set at? Reason for question is that my myson apollo pump works ok on high, but switch the high low switch to low and it runs all the time, even if the boiler hasnt fired up. I think it is currently set at 60. someone said that the low on the high low switch...

Hi Apollo myson high low switch on boiler - anyone tell me what temp these operate at / switch. I take it each side is connected to a stat, but how does the control work - eg it controls the pump running?

Hi how is the high low setting controlled on my boiler? long story but got water on the pump that blew it. replaced and if set to high the central heating and hot water works all ok. If set to low on hot water - the pump runs all the time. If I go to the clylinder strap stat and turn this...

Hi hadn't had to use the ch since last year, and due to the motorised valve breaking, had to change it and also the pump due to water shorting it and subsequently burning it out (possibly needs drying out) Fitted a new valve and pump When I put the central heating on, the pump appears to...

Hi hadn't had to use the ch since last year, and due to the motorised valve breaking, had to change it and also the pump due to water shorting it and subsequently burning it out (possibly needs drying out) Question when does the pump run? does it run with just central heating selected...

Hi I just had to replace the 3 way valve and the pump. The valve works fine - heating just the water or ch rads if selected. I changed this yesterday. However last night was aware that I think that the pump was continually running and also the boiler running. I don't think this is...

Hi All My story continued. Initial fault hot water working fine was turned on central heating switch and turn up roon stat and nothing happened looked at the honeywell motorised valve. It is T shaped. marked b, a and the one going down AB If I move the lever manually to its...

hot water working fine turn on central heating switch and turn up roon stat and nothing happens. looked at the honeywell motorised valve. It is T shaped. marked b, a and the one going down AB If I move the lever manually to its futhest extent, then the heating and pump kick in. If I...

motorised valve this i believe controls hot water or water and central heating. If i remove the motor, how do i reconnect it so that i know the motor engages the valve correctly? thanks

Hi Appolo boiler changed the thermocouple a few months ago as pilot light went out would not light. Had a few mvolts on there, but forum advised changing and this solved the problem. Here we go with my new problem hot water works fine, and seeing that I messed about with the motorised...

as it says on the tin where? Apollo boiler has a over heat stat connected mid way any info appreciated - also do they have pics so that I can confirm the correct unit. thanks

apollo boiler - noticed pump running or noide, but no hot water - heating. Pilot light out, restarted but when relaesing valve button for lighting it went out. Changed pilot light cover/jet as badly worn. Also heated thermocouple and getting about 25mV going to the valve. Thermostat switch...
