Direct Zone/Zone 1 setpoint in heating mode Par. 2001=

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 1 is configured as mixed, the value set in param-
eter 1112 will be used as setpoint
