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