@gary Thanks for reply, that's odd, defiantly something to look into. The two extinguished lights are for the bedroom and ensuite, the heatmiser in that room is set to 30degs and doesn't get anywhere near it (still trying to get WC balanced). The thermostat in the room shows flame symbol to signal demand but the lights are out as photo shows. Any thoughts on what might be causing it? The whole house is still too warm typically 22-23degs.
Cheers,
Neil.
I would suspect that just because you were told that thermostat is connected to that channel on the wiring centre it isnt.
I would turn down all the thermostats down so they aren't calling for heat and check all the lights are off, then turn them on one at a time and check which light comes on the wiring centre then you know which is linked to which.
Then you need to check which actuator is linked to that channel and where that UFH loop is going to.
The thermostat could be calling for heat for a room its not even in.
Do you have wired or wireless thermostats? Either way you can either change the wires in the wiring centre or move the actuators on the UFH manifold to the correct places its not difficult.
@gary Thanks, will try the thermostat thing Friday when home. Is there a way of telling if thermostats are wired/wireless? I think i'll need further guidance on moving wires once I've established what's going on and what's linked to where. My partner is very patient but she's beginning to show signs of doubt, she's continually baked or chilled depending on Ecodan settings.......shouldn't laugh! It may come to the point where I pay someone to come and sort it all out once and for all, I'm more than happy to have a go but working away isn't conducive to doing this.
Cheers,
Neil.
I believe the UH8 RF wiring centre you have is only compatible with wireless thermostats so I think that confirms they are wireless.
Once you have figured out which thermostat should be connected to which actuator/channel on the wiring centre they can be paired to the correct channel, no wiring changes would be require but pressing buttons on the thermostats and the wiring centre.
Another thought if they are paired to the correct channel on the wiring centre then they are too far away from the wiring centre to get the signal from them to turn on.
@gary Wifi is a little iffy at further reaches of the house. Although we do get phone Wifi in bedroom, if I push the button on UH8 the lights will come back on albeit for a short period. I'll try your suggestion on links to correct actuator.
What's your curve set to at the moment Gary? We're in similar geographical location so interested to know, also I'm a 5KW Ecodan, what size are you?
Thanks,
Neil.
@ngillam Wired / Wireless? If wireless, there will be a battery to power it, a wired unit will have power from the pump or whatever it is attached to. Wireless furthermore will have a receiver somewhere in the heat pump controlling equipment. Usually, the idea of wireless is that the unit may be placed wherever you require to detect the room temperature. The connection is usually made by Zigbee or some flavour of wi-fi. Regards, Toodles.
Toodles, he heats his home with cold draughts and cooks his food with magnets.
@ngillam Can't really compare houses ours is badly insulated circa 2003 185sqm detached house, 8.5KW heat pump. My flow temp down to 3C is 32C then increases 1C for every degree below that reaching 40C at -5C.
Attached to the wiring centre there should be an ariel, check you have one.
Instructions for pairing thermostats to wiring centre
@gary I have three of those aerials in boxes left on top of the fuse box.......Not happy with this install at all! Hopefully the pairing will make sense when in front of the units. Is it obvious where they need to be plugged in?
@gary No, only the two, need to work out how to remove from the wall for pairing, I know the battery cell can be removed but haven't ventured further than that. The wiring centre may have been labelled up incorrectly!? Hope to have answers this weekend.
Cheers,
Neil.
@ngillam you dont need to remove the thermostats to pair them to the wiring centre. if they can't pair in situ then they are too far from the wiring centre and therefore won't work. Not having the ariels attached won't be helping with signal range so screw in the ariels before you try to pair them to the wiring centre.
Before you do that it would be worth working out which thermostat is paired to which channel on the wiring centres to then follow the wire to the actuator to make sure that thermostat is attached to the correct actuator for the room its in.
Alternatively just unscrew all the actuators then they will all be permanently open so it doesn't matter if all the thermostats are connected to the wiring centre you just need 1 thermostat to call for heat to activate the heat pump.
