Will Comfort mode eventually learn/work for my hallway/bathroom?

[JezW]

I've recently fitted the wiser thermostat and two smart TRVs. I've positioned the thermostat just outside my bathroom, which has a large heated towel rail, without a TRV.

My issue is as follows:

-It's a large bathroom

-It has a large single glazed window

-The only source of heating is the towel rail (low heat output compared to normal rad)

All the above means that the bathroom can be quite cold, especially in the morning, if the heating doesn't come on very early.

I'm using comfort mode and set the thermostat temperature to 21c in the morning over a 1.5 hour period, but the thermostat never reaches 21c. Today it reached 19.5c, but has now moved into the next schedule, where it drops back to 19c.

Will the system eventually learn (using comfort mode) that it needs to turn the heating on earlier to reach 21c at the thermostat? Or are the factors I've listed above taking thermostat too far from normal operation/normal parameters and it will never reach 21c? In which case, I should simply set it to 23c for example, and then hopefully it will reach 21c...

I've read that comfort mode can start the heating up to three hours before the scheduled set point time. Therefore I don't think setting a higher temperature will do anything. It was the same again this morning, reaching 19.5c instead of 21c. I've brought hallway/bathroom start time back 1.5 hours to see if that sorts it.

Hi,

We can confirm, in comfort mode, the anticipation can't start earlier than 3 hours before the setpoint change as you said.

Hi David,

Comfort Mode is a useful feature, but its functionality could be enhanced by allowing it to be enabled on a per-room basis rather than as a global setting.

Hi @Fozzie1960 , thanks for your remark. Your proposal will be shared with team as idea of improvement for next releases.
