Adjustment, charge flow
For correct function of the heat pump over the entire year,
the charge flow must be correctly adjusted.
If an NIBE indoor module VVM or accessory controlled charge
pump is used for the control module SMO, the control tries
to maintain an optimal flow across the heat pump.
Adjustment may be required, especially for charging a sep-
arate water heater. It is therefore recommended to have the
option of adjusting the flow across the water heater using
a trim valve.
1. Recommendation if there is insufficient hot water and
information message "high condenser out" during hot
water charging: increase the flow
2. Recommendation if there is insufficient hot water and
information message "high condenser in" during hot
water charging: reduce the flow
