1. Product description
The CCR2 is a control used for optimising 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
2. Technical data
3. Installation
For easy access, the CCR2 control is installed in
the technical box on DIN rail 35 mm. Box 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 box are not included. It
4. Switching the control on
Before switching the control on for the first
time, disconnect all cables and connect a 24 VAC
source to the disconnected power plug. Use a
voltmeter to measure the voltage on the power
cable plug before it is connected to the control.
If the voltage is correct:
1. Read the instructions before you operate the
control
2. Disconnect all cables
3. Connect the power to the transformer (not
connected to CCR2)
4. Turn on the power to the transformer
5. Verified currency - 24 V
6. Connect the cable from the transformer to the
CCR2 input
The control should display its name and the
software version – CONTROLLER START MENU –
display according to point 5.
Before any plugs are connected to the control’s,
input and output connectors:
1. Set all parameters on the control
2. Make sure that there is no external voltage on
the temperature sensor plugs
3. Make sure that the voltage on the relay
contacts is not too high (max. 24 VAC)
is recommended to install the standard 24 VAC
transformer in the same box as CCR2 (not supply).
Do not install (and remove) SD card when the
CCR2 is connected to the current. It must be
switched off (risk of losing data).
