Hi,
I'm new to evohome, and after reading quite a lot on this topic, including this forum, there are a couple of things that i don't fully understand yet, so i'm looking for some advice.
my current setup is:
1 heat pump (on/off), controlled by 1 BDR91 and it's associated DT92E. (let's call it "master" BDR91/DT92E)
The heatpump is connected to underfloorheating with 15 loops.
Out of these 15 loops, 3 also have a BDR91 and associated DT92E (so 3 BDR91 and 3 DT92E additional) and each BRD91 (from these 3) controls an electric valve (on/off) on the underfloor heating loops.
These 3 valves/bdr91's are only there to limit the heat in those 3 rooms (and not the other way around. so the heatpump will only turn on when the "master" DT92E is asking for heat, and not those 3 slave DT92E's)
Since the heatpump need to be able to dissipate the heat when on, it will run water to the 15 loops all the time, except for those 3 rooms (where these valves can be shut off). So the result is that when the heatpump is on, it will run water to at least 12 loops.
Now, enter evohome :-)
I would like to have a similar setup, where
- the "master dt92e" is replaced by the evohome and controls whether the heatpump is on/off
- the 3 BDR91's and associated DT92E's are connected to the evohome (but again, only there to limit the heat, and not to turn on the master BDR91)
- use the 1 spare DT92E as a dumb temperature sensor (that cannot call for the heatpump to start or stop)
Can this be done?
(i know that there exist an HCE80/HCC80R, but i'm not really prepared to remove the existing system)
Thanks in advance!
