Hi.
Have just moved into a flat with a trianco Aztec electric boiler paired with a Horstmann Centaurplus C27 programmer. Apart from a big white tank and (supposedly) knowing how to set the timer, that's as far as my knowledge goes with this system. My problem as far as I know is the timer. When I switch on the hw the water doesn't heat but the central heating gets hot!?. The ch light on the timer doesn't come on but the central heating defiantly gets hot. Same if I press the boost button, I hear the system start an the central heating comes on again, without the water getting hot. If I press the ch button the heating comes on fine. In short both the hw and ch buttons only turn on the ch?!
There is a separate immersion switch I can use to heat the water, but this can become expensive I I forget to turn it off.
Any help please?
Sorry for the long first post and thanks in advance
