Yes think thats the issue the garage is very cold, on the mel cloud app it only shows the garage temp. Perviously before we went set compensation curve we called for heat from the salus thermostats which was ok, but as soon as we changed to comp. curve the house got lovely and warm even the hall which had struggled to get over 19.5 hit 21 and maintained that temp. I just wanted to set the temp back a couple of degrees to not waste energy thru the night but only way i can do that is to use the salus thermostats, or maybe buy a second wireless controller.
By the ways thanks for your imput its much appreciated only had the system about 7 wks so still learning.

I just time the ASHP to switch off 12-5am. The room temps drop a couple or three degrees and then warm up (slowly) in the morning.
Can’t you get that controller into the house? It’s only a two core cable.
once there it must be programmed to respond to actual room temperature
and it should be in a zone PERMANENTLY open with the salus controller set on maximum in that room (make it the biggest room of possible)

Posted by: @alec-morrow@sand OK this is the problem..the controller that will optimise the heat pump is not that one...salus controllers do not feed back to the heat pump in any meaningful way.FTC 5 OR 6 is the one that does that but it to be effective it needs to be in one of the zones in the house not in the Garage (although it may well be set up not to reflect the garage temperature)
You can also use a wired in thermistor or Mitsubishi wireless controller one with the FTC5/6. with Auto Adaptation. I think @sand has an older FTC2 though and I don't know if it can do this.
@sand I’d ask the ashp installer to do it..none of this stuff is simple. In fact he may have a straightforward answer as to why it’s not in the heated part of the house..
the upstairs one indicates that he knew what he was doing, but I see no benefit in the salus controls..
Professional installer
Yes I will ask him.
On the 5 minute handover we had with him he said to leave it on the target flow temperature setting with a flow of 60c. He told us to set it and forget it, but it used a lot of enery on that setting.
Posted by: @alec-morrow@flowboy ironically the technology upon which these systems rely (open therm) was developed at Glasgow university in the late 80s, and sold by Honeywell to a consortium of European boiler manufacturers for £1 in 1992
the rest is history…
No doubt having spent quite a lot of public money on the research before getting cold feet!
Yes we do, ufh downstairs rads upstairs, does that make a difference to the settings.
Posted by: @sand"Mixing control strategies".
This interested me because we are currently running on compensation curve all salus thermostats on manual. So ecodan is running system just using the salus thermostats as room thermometers.
I would like to set back the temperature on a night from 21 to 19 and have 2 options, either set back on the salus thermostats or change the Ftc to timer mode so the salus thermostats dont come into the equation, no mixing of control stratergies so the system doesn't gets confused.
I would be interested in your thoughts please
Hi Sand,
Do you wish to just lower your downstairs temperature from 21C to 19C, or also your upstairs temperature?
If it is the latter, you may be able to lower the temperature in both areas using your wireless remote controller using a schedule. As a trial during the daytime, lower the temperature setting on the remote controller by a degree or two and see if the temperature is reduced in both areas.
The upstairs is always set at 19 the downstairs is set to 21 so just wanted to set back downstairs to 19 overnight. We were told the wireless controller just worked the rads upstairs but I can try it downstairs, thanks.
