Good morning everyone
I am facing a problem with the hot water/heating programmer Drayton (LP522): although there are two different programs for the CH and the HW, the latter is always on.
In other words, when the heating system is on the water heater receives the hot water coming from radiators.
When the heating system is off, the water heater is making hot water using the internal electrical resistence.
Also, I tried to turn off the water heater through the programmer, but it is still on: the only way to stop it is switching off the electricity from the programmer.
From the experience gained in this case, I can assume that the programmer is not able to manage HW and Ch independently. However I don't know whether:
1) the programmer works in that way (in this case I need to upgrade it)
2) there is a wiring problem behind the programmer.
I am sorry for the long message, and I thank your for your answers in advance.
