General
ACS 310 is an accessory that makes it possible for
VVM 225/VVM 310/VVM 320/VVM 325 to control pro-
duction of cooling.
The cooling system supplies cooling from the heat pump
using a circulation pump via a reversing valve.
For the installation to work the cooling system must flow
freely, for example using a volume vessel for cooling.
Operating mode cooling is activated by the temperature
of the outdoor sensor and any room temperature
sensors, room units or separate room sensors for cooling
(if two different rooms are to be heated respectively
cooled at the same time for example.)
When cooling is required the cooling reversing valve and
the circulation pump are activated. Cooling production
regulates according to the cooling sensor and a cooling
set point value that is determined by the selected cooling
curve. Degree minutes are calculated in response to the
value on the external temperature sensor for cooling
out and the cooling set point value.

Caution
In order for the accessory to work, a NIBE
air/water heat pump must be connected to the
system.
