Hi all,
I just got a evohome installed (by some professional as I needed some boiler work, installing some valves on radiators that didn't have them, etc...).
My setup includes a condensing combi boiler for heating and hot water, an evohome controller + relay, 6 radiators with 6 HR92 valves, 3 radiators with normal valves (two will be
replaced by heated towel rails, one will be removed when I redo the kitchen in a few weeks). The radiators and their valves are all far from furniture and not covered by curtains.
I have a few problems/questions with the temperature controls and I haven't found the answers I need in the old posts.
The temperature detected by the valves when the radiator is on or still warm is several degrees (4 or 5) higher than the one in the middle of the room. On the other hand, the temperature is correct then the radiator is cold, so I cannot just change the temperature offset.
In the last two days I had to keep setting the room temperature to 24C until the centre of the room is warm (about 20C) and then decrease the set temperature to 21 or 22C so it will stay at about 20C.
Is this normal? I expected some difference, but not this much as it basically makes the system useless and impossible to control.
Could some DTS92 thermostats help? If I understand correctly, I can use those to pick up the temperature and use the HR92 valves only as actuators.
Is it possible to fix the DTS92 to the wall instead of just using the desk stand?
My other question seems to be about a potential bug in the software. Let's say that the valve (and controller and app) think that a room is a 20C, but it's actually colder, so I set the temperature manually (with the app or controller) to 22C. Immediately after doing that, the app/controller will report an increase of 0.5C in the detected room temperature, even before actually turning the heating on. This seems to happen about 50% of times. Does this happen only to me?
