Hello
Im having difficulties with my gas CH. Below is a list of the equipment.
Suprima 70L
Super Selectric Pump
Hercal Cylinder
Myson Power extra 2way motorised valves
Altech motor at top pipe to Cylinder
Honeywell L64B1004 at bottom of Cylinder (seems to flow in at top and out at bottom)
Adjustable bypass below pump
Thermostat (manual - adjustable from -20 to +30c)
(above all in garage)
Digital Timer in utility room
Digital Thermostats in hall and master bedroom - these have the function to be set at 6 different times/temps 7 days a week
The problem I am having is that the Boiler and Pump will not switch off at the set On/Off times that I have set on the Timer if the rooms are not to temperature on the Thermostats. Even when the timer is set to OFF (continual OFF) the boiler will continue to fire and the pump, well pump...
The only way I have found to turn the heating system off is by turning the room stats to below its current room temp.
Things I have done:
A plumber recently (last week) changed the motorised valve (altech) which runs IN to the top side of the Cylinder because the orignal valve was leaking. I am unsure if this has caused the problem as we only moved in last week.
Research on here suggests that it could be the motorised valves on the flow pipes. I have discovered that one valve is rusty and the other is slightly stiff. However it seems that the small motors can still turn them on/off - though I am not entirely convinced they are shutting fully. If I remove the motors and watch the rotation they turn freely when the thermos in house are turned up/down.
My intentions we're to replace the motors / valve entirely which will create a little bit of DIY wiring. Having now seen that the motors appear to be working I may just replace the rusty sticky valve instead reducing the chance of electrifying myself
Really Im looking for the experts to confirm that this is the right more or if not, point me in the right direction.
Thank you
