Nibe VVM 310 - External Adjustment Settings

Commissioning without heat pump
The indoor module can be run without heat pump, as
only an electric boiler, to produce heat and hot water,
for example before the heat pump is installed.
Connect the pipe for docking in from the heat pump
(XL8) with the pipe out from the heat pump (XL9).
Enter menu 5.2.4 System settings and deactivate the
heat pump.
NOTE
Select operating mode auto or manual when
the indoor module is to run with the heat
pump.
Pump speed
Both the circulation pumps in VVM 310 are frequency
controlled and set themselves using control and extern-
al heating requirement.
In the menu there are two operating modes for the
circulation pumps, "manual" and "auto". If "auto" is
selected, the circulation pumps are controlled automat-
ically by heating and hot water demands.

Post-adjustment, venting
Air is initially released from the hot water and venting
may be necessary. If gurgling sounds can be heard from
the climate system, the entire system will require addi-
tional venting. Vent the installation through the venting
valves (QM20). When venting, VVM 310 must be off.
