Hi folks,
I've got a potential problem with my Logic Combi ESP1 35. When the boiler is set to Central Heating and Hot water mode, the boiler indicates that there is a constant Demand for Central heating.
When the thermostats (TP5000 Si) are turned off (both pulled from the wall and also simply by turning off the heating either via temperature or timer) boiler continues to fire. The boiler indicates that the temperature of the system is always around the 50c mark and as soon as the temperature drops, the boiler kicks in and heats the water again.
I have a dual zone system with some form of valve system which is controlled successfully via the thermostats (photo attached) and as the radiators do not get hot unless triggered by one of the two thermostats i can only assume that it is working as expected.
Initially I believed that this was by design, however after finding a similar post on this site, I'm now not too sure.
I suppose my question is this; when the two thermostats are set to off, should the boiler be continuing to heat that water system or should it go into standby mode and allow the temperature of the system to drop until the thermostat kicks in to show a demand for central heating?
I've also included a picture of the thermostat wiring, which I believe to have been correctly wired.
Thanks in advance for any advice.
Shaun
