I fit only Honeywell.
The VH200 manual valve can be upgraded anytime to a;
- TRV eg HoneywellVT200
- electronic timed TRV
- Hometronic HR80 head
and, if needed, then converted back to a manual head, all by an end user with no tools. They are expensive but good. Fitted many thousands, only had two failures.
