MELCloud won’t control underfloor heating.
Hi everyone, hope you are all well.
Recently moved into a new build with an Ecodan R32, FTC6 and Tempest cylinder. The system did not come with a wireless interface (MAC-567IF) included so I bought one on eBay for £60 and installed it myself. I can control the hot water using the MELCloud app and I love all the data, but I can’t control the underfloor heating. The app shows the FTC6 Control Panel temperature (not the same as room temps), which I can control, but this does not activate the underfloor heating which is controlled by two UFH1 7 Day wireless thermostats.
Is there any way I can get control of the underfloor using MELCloud? One idea is to get 2 Ecodan Room Remote Controllers with corresponding receiver, but this will be a very expensive upgrade and will it even work? I’m pretty sure underfloor heating can call for Ecodan, but I’m not sure if Ecodan can call for underfloor heating…
Another idea is just to get a single PAC-SE41TS-E for sub-£50 and loose the two UFH1s, but would that work? And if it does work would it enable the Ecodan to heat both Zones?
Any thought would be much appreciated.
Thanks in advance.
Hi did u get this sorted.
We have a ecodan with underfloor heating downstairs rads upstairs.
We use the timer in the app, took me a while to figure it out, buts thats the easiest way I find to use. Not the timer on the FTC.
Hope that helps

Thanks @Sand, appreciated. Do you have non-Mitshubishi room thermostats? Are they wired? Any hints or tips on how you got it working via MELCloud?
I have made progress, but not with MELCloud. I worked out that my two Toplo UFH1 thermostats are wired, not wireless as I originally thought so I am thinking of swapping the two Toplo UFH1s for Tado Smart Thermostat V3 which will give me remote app control with geofencing. Like you, I have UFH downstairs and rads upstairs, so in time I will swap out the Honeywell thermostat upstairs for another Tado and put Tado smart radiators valves in each room.
I love all the data you get from MELCloud, I can control hot water remotely and Mitsubishi can check my system remotely so I that was definitely worth the £60 I paid for the wifi interface.
Hi we have the wireless mitsubishi upstairs to control rads then each room has a Intstinct thermostat , that can call for heat we have 7 of them, which we found frustrating, they dont have a wireless app controller they are wired. Our FTC is in the garage so we cant set just a standard temp across the board it just shows temp for that.
I just found it easier to use the timer in the app so all rooms are same temp with a small setback at night.
Last year we were paying 17p per Kwh then it went up to 27p looks like its going to be 34p so I dont want to be using ridiculous energy through the night.
So in the app last year it was set at 16 degrees thru night then at 8am 18 degrees thru day then 5pm 19/ 20 depending how cold it was, then back down to 16 overnight.
Last year we had no flooring so we may adjust the temps down if we need to this year.
Going to see how that goes. We had porcelain floors laid in March, had to cure so basically its been off all summer just heating water.
It took me a while to get used to the app but I really like it now, info out there bit technical so I just learnt by trial and error.
We also bought a delonghi heater that we used while floor was curing so may use that whilst energy crisis is on.
We were thinking of tado for rads which will still may do cos controller doesn't seem to work in our bedroom, too much tech i suspect so confusing for the wireless controller.
@sand thats very interesting. So is the temp on your app the same as the temp on the FTC Controller near your cylinder? I'm guessing you have been able to tell the system to ignore the 7 stats and just control the heating via the FTC Controller which means you can control it via MELCloud, is that right? I can not activate or control my UFH at all using the FTC Controller - only my hot water. Can you remember what you did to bypass your 7 wired stats? I'm guessing it was something on the FTC panel rather than MELCloud?
Home then action then timer, you may have to set a preset temp first, soz i cant remember.
Enable timer then set ur preset, times u want it to come on chage etc u need to do this each day
Think images are wrong way round but you get the gist.
By enabling u over ride the FTC
This way all thermosats are controlled by the app. So should call for heat
All at 10c at min so in effect off just hot water on.
Instict thermostats are set to manual, in effect they just glorified room temp gauges, they dont control anything just show how warm the room is
I really hope that helps
If images fuzzy just click on them
Normally UFH has its own stats and that calls the HP for heat. So it doesn’t work in reverse, turning up the heating in the Ecodan won’t force the UFH on.
Saying that I’ve just done this. I’ve taken the pump live feed out of the UFH and wired it to the Ecodan. Then I’ve left both zones open.
So the UFH stats do nothing now. Turn up the heating in the app and the UFH will fire up.
250sqm house. 30kWh Sunsynk/Pylontech battery system. 14kWp solar. Ecodan 14kW. BMW iX.
you would need the manufacturers own mixer module and wiring centre for UFH
