CCR3+ controller is part of AB-QTE solution
for one-pipe heating systems. It converts
one-pipe heating system (usually constant flow
system) into efficient variable flow system. This
innovative solution dynamically controls the
flow in the riser according to the load in risers by
return temperature control. There are few basic
rules to be followed, even more valid in case of
renovation:
• Set AB-QM according to the required heat
load of the riser/loop.
• Ensure correct radiator bypass flow setting
(typically around 25-35 %). If the resistance of
the radiator is much too high compared to the
bypass this may result in underflow through
radiator if the flow in riser/loop is reduced.
• Optimize flow temperature that is driven by
substation control (too high flow temperature
can influence efficiency of first radiators in the
riser/loop and result in oscillation of flow).
• Optimize return temperature that is driven
by CCR3+ (too high return temperature can
result in lower energy efficiency).
• Install temperature sensor in front of AB-QM
as close to last radiator in the riser/loop as
possible.
Following above rules will ensure optimal
control performance of CCR3+ as well as energy
efficiency and reliability of heating systems.
For further application insights please contact
Danfoss representative.

4. 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 VDC
transformer in the same box as CCR3+ (not
supplied).
5. Switching the control on
6. Switching on
7. Types of Logins and Access
Before switching the controller on for the first
time, disconnect all cables and connect a 24 VDC
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+)
4. Turn the power to the transformer on
5. Verified currency –24 VDC
6. Connect the cable from the transformer to the
CCR3+ Controller input
The LED diodes on device should blink at
start-up.
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 VDC)
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) + 7 VA x 20 actuators = 150 V
When controller is connected to power, LED
indicator start to blink. The meaning of LED
status is:
Controller has a built in WEB Server App to
communicate with all devices with html
browsers via following communication
interfaces:
• Wi-Fi communication port
• LAN cable connection (TCP/IP port)
LED Description
P (orange) – Power inside controller (+5V) Lights when DDC PCB is power on
D (white) – Data transfer indicator for LAN Blink when DDC is communicating by TCP/IP
S(orange) - Input power indicator (24VDC) Lights when power supply PCB is working
BT (blue)– Basic transmission indicator for Wi-Fi Blink when DDC is communicating by WiFi
A (red) – Alert status on I/O module LED lights when/if: to low temp., broken sensor
O1..4 ; 1-20 (green)– Digital Output Status Lights when Output is closed to 0V

Reset Wi-Fi password Available via long press on reset button (located on LAN port) for at least 5 seconds.
Wi-Fi password is reset to “admin00X” where x is the number of BT (blue) LED blinks.
Reset the setting only Go to firmware menu and click on “Return Defaults”
Reset password only (but not
change other parameters) Go to firmware menu and click on “Reset passwords”
Recovery (device can be
recover back to factory
firmware)
Via long press on reset button, power down and with access code “369” (code for recovery to
default firmware). To perform a recovery, you need to make these steps:
1. turn off power supply
2. press hardware button
3. turn on power supply, power led will be ON
4. hold button for more than 5 sec until ALL 3 leds turned ON
5. when all 3 leds is turned immediately release the button
From this moment you need to enter 3 digits code
In this mode there are two hardware button function:
- short press increase code number,
- long press switch to next code digit
Currently code number is signaled by lighting of led diode: blue led = 1 digit, white led = 2 digit,
orange led = 3 digit
Example to enter code 123:
- first led diode (blue) is turned ON, then make a short button press 1 time, blue led should
blink once
- make a long press until white led is turned on
- using short button press 2 times, white led should blinks 2 times
- make a long press until orange led is turned on
- using short button press 3 times, orange led should blinks 3 times
- if code is entered properly than recovery has started.
DO NOT TURN OFF POWER SUPPLY!

13. Modbus settings Supported functions:
1. Read holding registers (0x03)
2. Write single register (0x06)
3. Write multiple registers (0x16)
1. Read holding register start addresses:
from 0 to 195:
0– Valve output riser
(1=output closed - valve is open, 0=output open, valve
is closed)
1– Valve output pwm riser
(valve open in percentage: 0% .. 100%, unsigned decimal)
2– Temperature value
(valve open in percentage: 0% .. 100%, unsigned decimal)
3– Set temperature
(temperature in °C with one decimal place precision,
unsigned decimal --> example: 529 = 52.9°C)
4– Status(alert)*
- 0 - OK
- 1 - temp too low/high
- 4 - sensor closed (short circuit)
- 5 - sensor open (sensor not connected etc...)
Example: To get riser 6 temperature
Formula: (6(Riser) - 1) × 5 + 2(Temp Value) = 27
2. Write single register – data can be written into start addresses:
from 300 to 331
- from 400 to 435
3. Write multiple register – data can be written into start addresses:
- from 300 to 331
- from 400 to 435
