my system is the following.
boiler conventional potterton profile 100e
programmer honeywell st6400c
valve V4073A1039
pump Grundfoss super selectronic 15/60
room thermo honeywell T6360b1028
I will appreciate any help advise on the following 2 problems.
1. When i request Heating via the extra hour button on the programer it could be anything from 10 minutes to 25 minutes before the boiler kicks in. (However when i request hot water the boiler kicks in same time)
2. With the heating switched OFF and only hot water ON i find the upstairs room radiator which has trv gets hot on the top?
Thanking in advance
