Could someone please advise on the possible root cause of this problem, as well as tell me where the solenoid valve actuator might be located?
* Potterton Profile L Bolier
* Grundfos pump
* 1x Landis & Gyr, 1 x Honeywel Motorised Valves
* Honeywell strap-on cylinder thermostat
* Indirect HW Cylinder, (with Immersion heater NOT switched ON)
* Landis & Staefa HW & CH timer
* Digistat 1 wirless thermostat (Timer and Digistat connected in Series)
* Have two water tanks in the loft
1. When the CH is ON I get CH & HW. (CH feeds the HW Cylinder)
2. Haven't yet tried having only CH ON and not HW on timer. (Will try tonight)
3. When only the HW is ON, I get NO HW
4. Have turned UP Digistat to max
5. Have turned UP & DOWN thermostat at cylinder until it clicks on/off while HW is turned ON. Also checked thermostat continuity (power off and unplugged at time)
6. When HW system is set to ON the boiler does not kick in, even when HW is in use
a) If the problem was the solenoid valve actuator then I should always have either (HW) or (CH) or (HW & CH) at all times, I think.
- Any idea where the problem is?
- Also I can't find the solenoid valve actuator in the cupboard where the boiler & cylinder are, or under the floor when a few of the pipes disappear. (Does there need to be one?) Any ideas with this one?
Only been in the house 1 year. Was newly plumbed 2 years ago.
Thank you.
