CCR3+ Controller
LANGUAGE
No. Name Description
21 TRet(90)
Required return temperature for measure supply temperature: 90°C
Factory setting: 58°C
22 Integration time
Integration time of the control signal (depend of actuators type). The shorter time, quicker
temperature changes (no stable regulation). The longer time slower reaction for temperature
change (stable regulation).
Factory setting: 6 sec (for dedicated TWA-Z (NO) actuators); setting range 1-100
23 Proportional factor
Control gain of control signal (depend on actuators type). The higher gain control the bigger
valves reaction (no stable regulation). The lower gain control weak reaction for temperature
change (stable regulation).
Factory setting: 50
(for dedicated TWA-Z (NO) actuators); setting range 1-100
24 Dif. Time
Differential time of control signal. The longer the value, faster control in reaction to the control
value change - approaching to the set value but not reaching it yet. Too high value results in
unstable control.
Factory setting: 15
25 PWM interval
Time period of pulse width modulation (PWM}.
Factory setting: 10s
26 PWM min.
At »close« signal to actuator, PWM describes minimum % of open period to the actuator. Lower
the value, longer the reaction time of the actuator. Too high value can result in not closed valve.
Factory setting: 10%
27 PWM max.
At »open« signal to actuator, PWM describes maximum % of open period to the actuator. Higher
the value, longer the reaction time of the actuator. Too low value can result in not opened valve.
Factory setting: 90%
28 Fault temp min.
Set lower temperature. Temperature alarm output indicated signal when temperature drop
below this value.
Setting range between 0 °C and 50 °C
Factory setting: 0 °C
29 Risers Nr
Number of active risers.
Factory setting: 20
30 Current time
Set the real time »Clock, hour & minutes”
e.g.: 12:40
31 Current date
Sets the real date
e.g.: 2018-02-26
32 Alarm Delay
Alarm delay time (relevant for Output which: Over temperature or Broken Sensor).
Higher the value, longer the reaction time alarm signal.
Factory setting: 0 min
33 Alarm diff.temp.+/-
Set upper/lower deviation temperature counted from Required Return Temperature.
Temperature alarm output indicated signal when temperature exceed this range.
Factory setting: 5°C
34 Alarm Relay Type
Alarm output
StillOn – continuous alarm signal: O4 (24 VDC)
Pulse – pulse alarm signal 24 VDC every second
Factory setting: Pulse
35 Archive Frequency
Data archiving interval. The time can be set to any value between 10 seconds and 4 hours.
Factory setting: 1 min
36 Output O1
Alert Broken Sensor (default): O1 output is closed to common (C) when sensor is broken (sensor
is short-cuted or not connected)
37 Output O2
Alert Low Temp (default): O2 output is closed to common (C) when sensor temperature is
bellow Set. Temperature
38 Output O3
Alert High Temp (default): O3 output is closed to common (C) when sensor temperature is
higher than Set. Temperature
39 Output O4
N/A
: Selected Output O4 not in use
40 Pump protection Factory setting: YES
41 Summer mode
Enabled – Summer mode is switch on (valves are closed, Vx output closed to common (C)
Disabled – Summer mode is switch off (valves are operating in normal PWM auto mode)
Factor setting: Enabled

Shift T.Set 1 -
Shift T.Set 36
Shift return temperature valid for all setting points. It can be adjusted up and down. The lowest
shift setting is to 10 degrees (anti frost setting value).
Each riser can be adjusted individually, riser by riser (from 1 to 36).
Factory setting: 0±°C ; in range of ±10 °C
