I already installed the EVOHOME system for my heating earlier this week totally successfully and I am very happy.
I have an S-plan system (2 motorised valves), and an OSO unvented hot water tank. There is a bypass loop (via a differential Pegler USV16/22 valve) already installed.
Currently the heating is triggered by a BDR91 installed in place of a thermostat. The original "timer" is still present with the heating permanently set to on. In this way, it was a very simple install and things like pump over-run etc still function as normal (Potterton Suprima 60L)
I just wanted to validate a few things
1) I can leave the heating set-up exactly as is
2) I change the hot water on the old timeswitch to permanently on like the heating and install the hot water transceiver and second BDR91 in the airing cupboard where the motorised valves and S-plan junction wiring is all present
3) Does anyone have any experience on fitting the insertion temperature probe into the immersion chamber on an OSO tank? (i.e. Are there any gotcha's in getting a good fit with the probe in there, or anyone has any videos for fitting the probe on any unvented tank?)
4) I don't need to disable the heating motorised valve because I already have a bypass loop installed
Many many thanks for the help.
