Hi Folks, I have been running Evohome in a single zone configuration driving a BDR91 and using the HCF82 remote sensor for a year. The sytem works fine except for temperature overshoot which is a major issue for me. It always oveshoots by somwhere between 0.5 & 2.0C. My configuration is about as simple as it gets yet Evohome refuses to learn/accept I do not require overshoot and I do not need more heat when the set point has been met. My alternative non Smart thermostat using simple TPI leaves Evohome for dead on temperature control & overshoot. There are many threads on this subject with lots of folk thinking oveshoot is a design feature while others see it as design failure, I am of course in the latter camp. So is there anyone with a similar simple set up to mine that does NOT suffer from overshoot and poor temperature control ... If so I would much appreciate your story !
Other possibly relevant info and thouights
Well insulated house
Boiler return tep 55oC
Thermostat that gives great control & near zero overshoot is Drayton Digistat (outstanding piece of kit)
Of course Evohome is overkill in my configuration BUT is a configuaration that Honeywell recommends.
Are my expections on overshoot and stable control to high or do I need to continue with my far cheaper unit to get the performance I require.
I look forward hearing your success stories in taming the Overshoot !!
