Danfoss HPA2 Actuator, 4 Wire

Product Information

So....i started to look into the control systems for CH and HW, and they are pretty basic, I'm a maintenance electrician and have spent a lot of time working on industrial control systems. You must report any damages, shortages or incorrect items to Customer Support within 48 hours of delivery. I've just replaced a Danfoss HPA2 that was on the CH valve, the boiler was on all the time, god knows how long this has been like this as the boiler is in the shed and it's not something we look at all the time, i just happened to be walking past the shed when i hear the boiler fire up and thought that's strange as i knew the heating was set to off, anyhow i replaced the actuator and all is good.
