Heating and cooling – ground / ground water as heat source
Passive cooling with brine-to-water or water-to-water heat pump
Passive cooling station with cooling controller
PKS ..
Module for passive cooling via borehole heat exchangers.Consisting of heat exchanger, brine circulating pump, temperature sensor,
passive cooling controller; 3-way distribution valve with electrothermal actuator included in the scope of supply.Cooling operation
mode is added to the existing heat pump manager by an electronic connection between the heating controller and the cooling con-
troller (where the software versions of the heating controller and the cooling controller differ, a software update is necessary and must
be bought from after-sales service).The components are permanently mounted in a white sheet metal casing, which can be mounted
vertically or horizontally.

Passive cooling controller
WPM PK
WPM Econ PK
Wall-mounted cooling controller with temperature sensors to record the flow and return temperatures. The passive cooling controller
adds cooling operation mode to the existing heat pump manager (where the software versions of the heating controller and the cooling
controller differ, a software update is necessary (subject to a charge)). Both controllers are operated within the network and control a
combined system for heating and passive cooling with brine-to-water or water-to-water heat pumps. The cooling capacity is transferred
via a heat exchanger not included in the scope of supply. This heat exchanger must be configured according to the cooling capacity to
be transferred, the volume flow and the water quality.
