hi there ,
does any one out there have reoccuring problems with danfoss hpa2 actuator heads ,i have fitted 4 in four years on my own system,the micro switch for the pump/boiler control keeps sticking on causing the pump to run all the time with the valve shut.this valve is fitted to the central heating but the hotwater one is a drayton which has been ok,they are both wired together on the orange and grey wires so one valve doesnt take more electrical load than the other ,its beginning to get a bit expensive and frustrating the last valve only lasted a month ,the one before 18 months,are they poor quality or is there something im overlooking,just ordered a sunvic replacement now to see if that will last any longer.look forward to hearing any thoughts on this.
