Posted by: @derek-mPosted by: @kev-mNo, I lost it when they installed MMSP in early October! Flow and return temps are available without MMSP and I can still see them in Melcloud. I assume they are from different sensors to the ones on the MMSP energy meter. The meter part of the energy meter is connected to the FTC6.
Hi Kev,
I have just noticed under section '5.1 DIP Switch Functions' of the FTC6 manual, that there are some DIP switches that need to be changed when MMSP is installed. It would appear that SW3-4 and SW3-8 need to be changed from off to on.
@kev-m also note that the manual specifically says that you have to power off the whole system before you flick those dip switches.
Speaking of manuals, here are the links for the MMSP Quick Start Guide and the MMSP Hardware Installation & Configuration Guides. They explain what all the different sensors are that it involves.

Thanks Justin. My heat meter is slightly different from that one in that the return sensor fits directly into the meter rather than a t-piece. I do find it a little concerning that not only do I now know what a heat meter is and how it's installed, I also even know the detailed differences between slightly different models from the same manufacturer! Who's have thought it...

Be careful Kev, they say 'a little knowledge can be a dangerous thing'. LOL
Hi Everyone,
Could I ask that if anyone carries out any of the suggestions provided on the forum, that if possible they provide feedback, good or bad, so that others may benefit from their experience.
'All is quiet on the western front', or could it be that everyone is busy adjusting their system to improve efficiency?

I think it's just that it's the weekend Derek. Remember them? 😉

I'm afraid I get confused, since the whole week is a weekend for me. 😋
There is normally an increase in traffic on the forum at the weekend, when people have more time on their hands. It obviously means that they are happy with their system's performance, or are desperately searching for a cheaper tariff. 🙄
@derek-m We are waiting to hear from the developer as we have been told not to touch any controls in the loft otherwise we jeopardise the warranty from Daikin. One neighbour has ignored this and has been changing settings, monitoring the system and feeding this back to the rest of us while we await the developers response. He has just told us he thinks that the back up system is coming on all the time which is costly, as it is set to come on at 0 and he has changed his to -5. We are not sure if this is the case with our system or not and he is going to monitor the change he has made to it over the next few days and feed back to us all so we can jointly pursue the developer to allow us to change our own systems or at least check them to see if they are working efficiently. We suspect not due to energy usage but no choice other than to wait while they respond.
Whilst it’s quiet then 🙂
I just had this from my ASHP installer when I asked them about weather compensation mode - I have a LG Therma V, with UFH downstairs and radiators upstairs. Would welcome feedback on their reply from this audience.
"Hi Dan,
All good here thanks. Glad to hear you’re both on the mend, it’s a tough gig being ill with a little one isn’t it!
When we have rads and UFH working together we tend to find using the weather compensation curve is not particularly effective. It can mean that there’s low temperature water in a convective radiator panel which doesn’t provide sufficient output. Our customers with similar set ups are far happier to hit a set flow temp of 50/55 which ensures the panels convect warm air into the rooms.
You can experiment with using the weather compensation mode to see if it suits, but we would recommend just to keep the set flow temperature. Ultimately the thermostat will turn off once it’s hit the set temp so the heat pump will be operating for a shorter period of time at a slightly higher flow temperature and you’ll find little difference in the ultimate efficiency. You could try adjusting the set back temperature by a few degrees which would mean the temperature in the house is maintained.
Hope that makes sense and do come back to me if there are any further issues re. upstairs heating."

Hi LittleRed,
Has anyone carried out the simple test that I suggested? Please ask your neighbour, who appears to be more proactive, to measure the ambient air temperature well away from his ASHP, and then to measure the air temperature at the rear of his ASHP.
If there is a difference in temperature then your heat pumps may be sitting in a 'cold well', in that they are pulling the cold air coming out of the front, back into the rear. This may be the cause of your backup heaters operating. What is your energy usage like on warmer days?
