BMS Feedback
For giving feedback to the BMS system
this output gives a 0-10 Volt signal as
indication of Load.

0-10 Volt input (Padin 1-2-3)
Load and temp control via an 0-10 Volt
dc input. When 0-10 Volt is selected the
system can only be controlled with this
system.
HCs + DHW changeover
External controller selects if the system
can only be active for DHW or for CH
and DHW
Heat Generation Lock
As long as the input is Open all heat
requests are blocked.
Padin 4
Take in account PADIN 4 is 5 Volt max
where 1, 2 & 3 are 24 Volt.
