The system I have is a thermal store with a gas boiler. There are two pumps, one for the boiler and one for the CH radiators. The system was originally installed with an oil fired boiler when the house was built in 1992. The boiler was changed to a Worcester Bosch around three years ago.
The original literature provided with the Flowmax store says the boiler should be set to 80-84deg and the store to 4 deg below this. The store thermostat is a Honeywell L6188B 2034.
The Issue I have is that the boiler pump runs continuously irrespective of CH settings. It seems that the boiler reaches temperature (82 deg) and goes off, but since the store temperature has not been attained, the boiler pump continues.
I have looked at the L6188B 2034 info on the internet, but the information, apart from being in 12 languages is hopeless. I cannot find how to set it up apart from a) there is an internal rotary wheel adjuster and the overall range is 70 to 140 deg.
Any comments on how this should be set up and how to proceed would be most helpful.
