CCR3 Controller
The CCR3 Controller is a controller used to control
return temperature in one pipe heating systems
with functions such as temperature registration
and monitoring riser temperature. The controller
is connected to thermo actuators type TWA-Z (NO)
and remote temperature sensors PT1000, type
ESMC installed on each riser.

Installation
For easy access the CCR3 Controller is installed in the
technical box on DIN rail 35 mm. Box with DIN rail
should be mounted in the wall (sub-station or boiler
room) as close as possible to the heat source. DIN rail
and box are not included. It is recommended to install
the standard 24 VAC transformer in the same box as
CCR3 (not supplied).
Before switching the controller 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 controller.
If the voltage is correct:
1. Read the instructions before you operate the
controller
2. Disconnect all cables
3. Connect the power to the transformer (not
connected to CCR3 "one")
4. Turn the power to the transformer on
5. Verified currency – 24 V
6. Connect the cable from the transformer to the
CCR3 Controller input

The transformer power depends on numbers of
actuators (number of risers in heating installation).
For standard application (16 actuators-16 risers)
30 W transformer is recommended, (for 32
actuators-32 risers) 60 W recommended.
Do not install (and remove) SD card when the CCR3
is connected to the current. It must be turned off (risk
of losing data).
The controller should display its name and the
software version – CONTROLLER START MENU –
display according to point 5.
Before any plugs are connected to the controllers,
input and output connectors:
1. Set all parameters on the controller
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)
