T BY PWR
Gen-set power is controlled to keep the
required temperature, that is measured
via an analog input.

Export limit
Limits export to the mains in the
baseload mode. If the function is
enabled, the gen-set power is limited so
that mains import is always higher or
equal to the setpoint Import Load.
ProcCtrlSingle: Export limit = ENABLE,
Import load
Warming
The controller limits gen-set power for
requested time or until the water
temperature reach the requested value.
After warming the gen-set goes to the
requested (e.g. Baseload) power.

Warming temp; Max warm time
Peak shaving
Automatic gen-set start/stop based on
object (load) consumption. Can be
based on measured kW or kVA.
