The CCR2+ is a control used for optimizing
the thermal disinfection process in hot water
systems with functions such as temperature
registration and monitoring circulation hot water
systems. The control is connected to thermo

Installation
For easy access, the CCR2+ controllers should
be installed in electrical enclosure on DIN rail 35
mm. Enclosure with DIN rail should be mounted
onto the wall (sub - station or boiler room) as
close as possible to the heat source. DIN rail and
enclosure are not included.

It is recommended to install the standard 24
VDC transformer in the same box as CCR2+
(not supply). The transformer power depends
on numbers of actuators (number of risers in
heating installation). To select proper power
transformer please follow formula: 24 V 10VA
(controller) + 7 VA*/per each actuator
Example (building with 20 risers):
10VA (for controller) + 7VA x 20 actuators = 150VA
