Smart grid functionality by digital input on terminals:
119.1/COM (Smart grid 1)
115/COM (Smart grid 2)
1 open & 2 open
Normal running
1 closed & 2 open
EVU = blocked heat pump & aux heater (risk of freezing).
1 open & 2 closed
Comfort (increased room temp & hot water)
1 closed & 2 closed
Boost (Further increased temp and also use of aux heater if
possible)
Settings are not adjustable, function does not need activation. Smart grid can e.g. be
used to connect to solar panels or tari control. Switching between e.g. Normal and
Comfort can be useful. Large changes of running conditions may increase use of aux
heater. (Note especially that Boost mode often may use excess aux heater due to smart
grid specic regulations.) Settings may be subject to changes without update of this
manual. As many settings are xed, the functionality may not be suited to all applications.
