VI.D3.A3.02
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
Start process
After switching the controller detected SD card on
and verified card memory.
If the card is placed correctly, the controller will verify
the present files:
• access
• one set
• all set
If the above-mentioned file is detected, the
controller will ask whether it should be used or
aborted.
If no files (new card, used for the first time) there will
be no request.
The next controller will automatically generate a folder
with files:
• folder ACCESS:
allow change of access code to menu (details
on request or www.danfoss.com side)
• folder DATA: file with record date folder SETTINGS

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)
with files
- all set: file with settings. Each time the of control is
switched on, setting parameters are archived. This
function provides verification history of all settings
- arch.set: file with archive of all settings.
Switching the controller on for the 2
above-mentioned record file the request procedure
for setting change or abortion will start.
Display information during the start process
After switching the CCR3 Controller on, the LCD
display automatically presents the start menu.
