Hi,
A few weeks ago, I had some issues with my heating. The fault was found to be a damaged cable in the Kitchen wall, which was repaired / replaced. At the same time I found the 3-way valve in the airing cupboard to be leaking when set for heating. For the last few weeks I have had the 3way valve actuator wiring disconnected and have just been using the system for hot water.
Today I finally got round to replacing the 3-way valve body and put a new (but not tested) actuator head on as the old one had visible signs of water damage.
I have wired everything up, but the boiler will not fire when only CH is called for by the programmer. Nothing trips out, the light on the programmer illuminates, and you can hear the relay click.. but nothing happens with the boiler. (I have checked and there is power getting to the wiring junction in the airing cupboard)
HW is working fine..
My assumption is that I have two faulty 3-way valve actuator heads, but before I buy another one to check, I was hoping someone could clarify if the actuator could cause that fault ?
My system is as follows;
Ideal Classic FF350
Salus EP200
Salus RT500
Danfoss HSA3
Danfoss Tank Stat
I have wired the HSA3 up as follows;
Blue - Neutral
Brown / White -Room Stat control
Grey - HW call from Tank Stat
Pink - HW off from tank stat
Thanks.. Alex.
