Hello freinds,
I just moved into a flat and I put the system on.
Everything is running well but I've noticed the pump is running 24h a day even if the CH is OFF and HW is ON and the pump is very hot. The boiler knob is set to 1.
If I put off the HW, the pump stops.
As the pump is runing non stop, the boiler does not burn non stop, just sometimes.
I do not know if this was happening before or is just a recent issue, I just moved in.
Is this normal or could be a danger?
Plese see below the wiring diagram.
Boiler: POTTERTON Prima F 50
Room Thermostat: Dryton acl
Pump: Grundfos UPS 15-50
Valve: Danfoss HSA 3
Boiler Thermostat: Danfoss AT
If you need further information, please ask.
Also, I was thinking to replace the programer with FP715 SI to be able to set separate times for HW and CH but semms like the CH is not going ON if the HW is OFF.
Is this normal as well, please?
Yours faithfully,
G
