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

Possible choices:

Set disinfection temperature.
Disinfec tion is initiated when the temperature on sensor S0 exceeds the set temperature.
Exceeding the set temperature on a riser sensor (S1 … S20), triggers the disinfec tion time
countdown for the given riser.
Factory setting: 65°C
Set disinfection time in the risers.
Disinfection time countdown is independent for each riser. Minimum required and maximum

Electronically controlled circulation temperature after disinfec tion in riser. The CCR2+ can
maintain the requested circulation temperature in the riser after the disinfection process. This

Number of risers connected to the CCR2.
Factory setting: 20
Function used for big systems. System expansion is done with several CCR2+ Controllers (with
connected CCR+ Slave Unit on each), which are connected:
Sequence – disinfection step by step (rst primary CCR2+ Master with CCR+ Slave Unit, than
secondar y CCR2+ Master with CCR+ Slave Unit, etc), If disinfection signal appears, the disinfection
process starts only in primary CCR2+ Master (with Slave Unit) and after implementation (successful
performed or not), output O2 becomes shor tcut with C, which allows the start of the process in
secondar y CCR2+ Master (with Slave Unit). When the last riser is disinfected, the primary CCR2+
Master will send a signal to ECL (or another control) and the supply disinfection temperature
returns to comfort temperature.
Parallel – disinfection is per formed at the same time. If disinfection signal appears, output O2
becomes shortcut with C. This is the signal for CCR2+ to start the disinfection. Parallel function
allows the start of the disinfec tion in all system (all CCR2+ with CCR+ Slave Units in the same time).
Main CCR2+ Master revokes the disinfection order for other CCR2+s (with CCR+ Slave Units).
Factory setting: Parallel
Integration time of the disinfection temperature (and circulation temperature) sustenance process
in risers controlled by MTCV valves. The shor ter the time, the quicker temperature changes (no
stabile regulation). The longer the time, the slower reaction for temperature changes (stable
regulation).
Factory setting: 60 sec
Proportional factor of the disinfection temperature regulation (and circulation temperature)
in risers is controlled by MTCV valves. The higher Propor tional factor will eect in the bigger
valves reac tion (no stabile regulation). The lower Proportional factor, the weaker reaction for
temperature change (stable regulation).
Factory setting: 100
Information about Temperature in installation (for BMS alarming only).
Setting range between +10 °C and +100 °C.
This setting is used for temperature alarm output when real temperature in system exceed upper

Disinfec tion sources for running disinfec tion and continuing the process, There are a few
combinations which allow initiation of the process based on one signal or in relation to many
needed signals.
Disinfection is initiated when:
-S0: sensor S0 reports a temperature higher than the disinfection temperature
-B1: input shorted to ground,
-S0+SCH: sensor S0 reports a temperature higher than the disinfection temperature in the
scheduled time period,
-B1+SCH: B1 input shorted to G (ground) in the scheduled time period, SCH - week ly schedule
runs and continues until it is complete, even if schedule was to terminate it,
-SCH: weekly schedule runs and continues until it is complete, even if schedule was to terminate it,
-S0/B1+SCH: B1 input shorted to G (fault to frame, ground) or sensor S0 repor ts a temperature
higher than the disinfection temperature in the scheduled time period,

Setting is active, when dividing is Enable
Controller start disinfection with less number of risers set in »Start riser number«. Rest of risers are
not active. When disinfection in started risers is nished, rest of risers are sequently ac tivated and
disinfected. If disinfection progress is less that Min.Div.Adv., risers will be divided.
Factory setting 20. Cannot be more than Risers number
Factory setting: 20
To be used when input source is not stable (B1: f.ex. thermostat switch, or S0: temp. source is not
stab le)
Timer will start to count down the disinfection timeout when B1 is open or. S0 temp. is less that
Dis.Set.Temp.
Timer is reseted if S0 temp. is higher that Dis.Set.Temp. or B1 input is closed.
In case of timeout count down to 0, disinfection will be stopped with timeout fault.

firmware)
Available via long press on reset button (located on LAN port) for at least 5 seconds.
Wi-Fi password is reset to “admin0 0x” where x is the number of BT (blue) LED blinks.
Go to firmware menu and click on “Reset passwords”
Via long press on reset button, power down and with access code “369” (code for recovery to
default f irmware). To perform a recover y, 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 but ton 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 nex t code digit
Currently code number is signalled 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 shor t button press 2 times, white led should blinks 2 times
- make a long press until orange led is turned on
- using shor t 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!

1. Read holding registers (0x03)
2. Write single register (0x06)
3. Write multiple registers (0x16)
1. Read holding register start addresses:
from 0 to 279:
0 – Valve output riser
(1=output closed - valve is o pen, active in disinfec tion;
0=out put open, valve is closed)
1 – Valve output pwm riser
(valve open in percentage: 0% .. 100%, unsigned decimal)
2 – Temperature value
(temperature in ° C with one decimal place pre cision,
unsigned deci mal --> example: 529 = 52.9°C)
3 – Is in disinfection group
(1=valve is in disinfection gr oup of valves, which is
in active disin fection state, 0=valve is no t in active
disinfectio n group of valves)
4 – Disinfection progress
(total disinfectio n progress in %)
5 – Disinfection time to end
(remaining tim e to end in sec.)
6 – Disinfection status*
Example: To get riser 6 temperature
Formula: (6(Riser) - 1) × 7 + 2 (Temp Value) = 37
