My V3+ setup is not properly supporting zones
I have a very simple installation. There are 3 heating zones.
1) V3+ Wireless Smart Thermostat [incl. Programmer with Hot Water Control] for Zone 1 & Water
2) Add-on Wired Thermostat for Zone 2
3) Add-on Wired Thermostat for Zone 3
The TADO Programmer always turns on the valve for Zone 1 when any heating is requested. Example: If I manually turn off Zone 1 in the TADO app and leave Zone 2 turned on in the TADO app, then the TADO Programmer sets the valve for Zone 1 to on: That is very strange behaviour!
Plumbers have investigated and they tell me it's very strange and that the Smart Thermostat and TADO V3+ Programmer appear to not support zones. Plumbers suggest I can fix my problem by adding another Add-on Wired Thermostat or Zone 1, and stop using the Wireless Smart Thermostat. Alternatively, the plumbers suggest there might be a setting in TADO that enables support for zones.
What are your thoughts please?
