8.3.3 Settings for operation modes 2.01 .. 2.05
For the following modes of operation:
2.01 Temperature control
2.02 Temperature control depending on outdoor temperature
(Special function: Sensor connection at E2, display and settin under E1)
2.03 Temperature control with additional functions (heating, shutter, temp. monitoring)
2.04 Temperature control with two sensors.
- comparison with control to higher value „E2 Function“ set
to comparison „4E“. display during operation: "Control value".
- Alternative: Average calculation of 2 measuring places Display during operation:
"Average E1 / E2 („E2 Function“ set to „3E“ )
2.05 Temperature control with 2 sensors, regulation on differece temperature
display during operation: "Value of E1 - E2 in K, E1 = reference temperatur, E2
causes positiv (E2<E1) or negative (E2>E1) difference
Setpoint 1
Setting range: -27 ... 75° C
Setpoint 2
„Setpoint 2“ (factory setting OFF)
e.g. reduced value for night operation. Switch over by digital input .
(As long as no allocation has been carried out: Display: - - - - -
F IO Setup).
Pband (Control range)
The control response can be adjusted to the system conditions
- small control range
= greater amplification and shorter control times
- big control range = longer control times and higher controller stability
Setting range: 0-102,0 K
Min. Speed „n-min“ (minimum output voltage )
If required setting of a minimum output voltage e. g. basic speed (minimum airflow rate) of
connected fans.
Setting range: 0 % → 20 % up to 100 % (or Max. speed).
Max. Speed „n-max“ (maximum output voltage)
If required setting of a maximum output voltage, e. g. speed limiter.
Setting range: 100 % up to „Max speed“.
Manual mode
OFF = automatic control as function of the set parameters
ON = automatic control without function, speed setting in menu “Speed manual“
Speed manual
Manual speed setting without influence by the external signal
Activation by menu „Manual mode“ or external contact at digital input (F IO Setup).
For information about deactivated regulation the adjusted value for manual speed
is indicated alternating with the actual value
