Our new ASHP system is fitted with a Grundfos UPS3 (modern 4 bedroom detached). It was set on the highest constant setting, 3. Would I be able to run it in Proportional-pressure mode I, II? If I placed it in this mode , what would I look for to check it's success or failure? thanks dave

I'd not thought of this scenario, we get a lot of solar gain from our conseratory

Yes, I agree, it looks like the Nest is an overriding on/off switch, with no linking of the temperatures. I plan to run it on weather compensation, so feel as though I can now do that! My next query is how do you program Setback is it in the scheduling menu, I've yet to try doing this? Is there any guides as how if to use Heat Pump setting/Quiet Mode, would you time this to be the same as our setback? dave

I'm trying to get to grips with the controls on our new Ecodan 8.5Kw heat pump. This thread has been very helpful - thanks all. Our system has been fitted with a Nest remote thermostat. To use the fixed temp mode or the weather compensation mode on the FTC unit, I need to trigger the nest thermostat to call for heat. When I select room thermostat mode on the FTC unit it shows a different room and call temperature setting than on the Nest. Is there a way to get the room temp and call temp from the Nest to the FTC unit? I guess the auto adaptive heating option on the heating pump will not work properly , and the call temp on the FTC needs to be set to at least the maximum I'll call on the Nest. Thanks for any insights. dave
