Zone 2 heating setpoint in 0 and 3 heating modes
The thermal unit adjustment determines the boiler set-
point in heating mode, using the highest value among
the requests of all the active zones (Par. 1101, 1201,
1301)
If Zone 2 is configured as mixed, the value set in param-
eter 1113 will be used as setpoint.
