Description
Factory setting and
(max. / min values)
EK - District heating
EK6 - Max flow temperature
Flowtemperature will be limited to maximum 45 °C if underfloor
heating is selected in EK1
Flowtemperature will be limited to 90 °C if radiator heating is
selected in EK1
EK7 - Valve time (sec)
Time for 3-point control valve from fully closed to fully open
(depends on actuator and valve stem configuration). Please refer
to valve supplier manual for this information.
EK8 - Max return temperature
If max return temperature exceeds the temperature setpoint, then
the valve will close incrementally untill the return temperature
setpoint is archieved.
EK9 - Neutral Zone
Hysteresis for temperature control via PID
EK6: 45°C
(20 - 65°C)
EK7: 150 sec
(1 - 255 sec)
EK8: 50°C
(25 - 70°C)
EK9: 1°C
(0 - 10°C)
EK - Space heating
control
EK10 - Heating PI P
PI controller P-band
By increasing this value the controller will try to reach the setpoint
temperature faster (with a risk of overshooting the setpoint)
EK11 - Heating PI I (x10)
PI controller I-band
By increasing this value the controller will try to reduce
overshooting / offset of temperatures (with a risk of slowing the
controller down)
EK12 - Heating Reg time
PI controller regulation time
By increasing this value the controller will be slowed down as time
between recalculation of valve position will be increased
EK10: 20
(0 - 255)
EK11: 50
(0 - 255)
EK12: 5 sec
(1 - 120 sec)
EL- Modbus
EL1 - Modbus adress
Modbus slave adress of unit
EL2 - Modbus baud rate
choose either 9600 or 19200 baud depending on the application
type
EL3 - Modbus Parity
choose odd or even depending on the application type
EL4 - Modbus Modify
choose off or on depending on the application type
EL1: 20
(1 - 247)
EL2: 19200 baud
(9600 baud / 19200
baud)
EL3: Even
(None / Even / Odd)
EL4: On
(On/Off)
