As I said above hive is connected to zone 1 heating and zone 2 thermostat is untouched and do not intend to move to hive after this experience. I hear if I need to go for multi zone need to have another hive receiver and multi zone thermostat.Hot water on needs to be 3 take out link between L and 1
As Shaun said on #5 really needs a single controller as well to separate heating zones.
One question..in hive wiring of that which would go to 3 ? Would it be one already wired or different one ,if it is easy question to answer.
