Downstairs I had a 12 port Hetta underfloor system installed by a plumber. Upstairs I installed an 8 port Hetta system myself using the existing pipework which had an old system on. Both systems are now fully Hetta with exactly the same components on (wiring centre, manifold, actuators, wireless stats).
The Hetta actuator has a clip on the plunger which you remove when you have attached them to the manifold which I did upstairs and it pushes the pin down closing the loop. When I call for heat the plunger pops up and you start to feel heat in the pipe. Stop asking for heat and the plunger goes down as it should.
Downstairs however the actuators have all got the clips still attached which means the plunger is in the open position so when one zone is calling for heat all the zones get heat however when I tried to remove the clips the Hetta wiring centre doesn’t open the actuator so all the zones get heat except the one that is calling for it. Even when the particular zone is turned off the plunger doesn’t go all the way down so I’m wondering why there is a difference and what can I do about it? It is happening with all the actuators on all the zones even if I swap them with actuators off my upstairs underfloor this discounting any possible issue with tue actuator. It can’t be very efficient filling all the zones with heated water every time one zone is calling for heat?
Has anybody experienced anything like this before?
