Riser Rx – riser status information:
-OK: disinfection finished successfully
-DisFault: disinfection has failed in riser Rx

Dis. status
-SensFaultL: temperature too low or sensor or shortcut to ground in sensor circuit
-SensFaultH: temperature too high or no sensor or break sensor circuit

Description
Is disinfection permitted?
Possible choices:
33
Disinfection
Enable – disinfection permitted
Disable – disinfection is switched off
Set disinfection temperature.
Disinfection is initiated when the temperature on sensor S0 exceeds the set temperature.
Disinfection
34
Exceeding the set temperature on a riser sensor (S1 ... S20), triggers the disinfection time
temperature
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
35
Disinfection time
recommended time depend on the disinfection temperature and should be selected from the
table in chapter »Temperature set in the circulation risers and disinfection time«
Factory setting: 15min
Electronically controlled circulation temperature after disinfection in riser. The CCR2+ can
maintain the requested circulation temperature in the riser after the disinfection process. This
Circulation
36
function is recommended for control valves with only actuators (PI control signal). For self - acting
temperature
valves like MTCV (with basic thermostat element ) recommended setting is 5 °C.
Factory setting: 5°C

Dividing risers into groups:
Enable – when the disinfection progress is slower than the set progress in MinAdvan

Disable – switched off regardless of the disinfection progress
Factory setting: Enable
Group division period. If dividing is Enable, Controller will calculate the average disinfection
progress of active risers, between Divide time period. If in divide time period progress of

disinfection is less than Min. divide adv. Active risers will be automatical divided to half. New
active group will continue with most promising (hottest) risers.
Factory setting: 20 min

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 (first primary CCR2+ Master with CCR+ Slave Unit, than
secondary 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 shortcut with C, which allows the start of the process in
secondary 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
41
CCR System
returns to comfort temperature.
Parallel – disinfection is performed 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 disinfection 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 shorter 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 Proportional factor will effect in the bigger

valves reaction (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.
Required
44
This setting is used for temperature alarm output when real temperature in system exceed upper
temperature
and lower deviation count from Required Temperature.
Factory setting : 55 °C
