Control system
ÄssäControl is a new-generation logic-based control
system designed especially
for the control of ground
source heating systems. It
guarantees accurate heating
- thereby reducing energy
consumption - and the production of domestic hot
water.
Using the ÄssäControl control system in Lämpöässä
ground source heat pumps,
you can control the cooling
of rooms and the heat source external to the ground
source heat pump unit in
bivalent and backup system
solutions.
A wide range of accessories
enables the automatic rotation of compressors and a
remote connection to the
control system.
