Control Functions
The controller is designed to control binary heating and/or cooling systems.
Setpoint
Minimum and Maximum Set Point Limits
: Limits the adjustable range of the loop set point. The limits for heating and
cooling sequence may be chosen individually.
Control Sequence
Economy set point shift X
SBY
: This function shifts the set point while the operation mode is Economy. The heating set
point W
H
is reduced and the cooling set point W
C
increased by the value of the Economy set point shift X
SBY
.
Dead Zone Span X
DZ
: The dead zone span lies between the humidifying and the de-humidifying set point.
Switching Hysteresis
: Defines the difference between switching on and switching off an output. A small hysteresis will
increase the number of switching cycles and thus the wear on associated equipment.
Delay OFF:
Prevents a too short running cycle for the control output by setting a minimum running time.
Delay ON:
Prevents a too short stopping cycle for the control output by setting a minimum stopping time.

Temperature setback (TSET)
Shift the humidity set point towards a defined TSET setpoint
CP 15
depending on the outdoor temperature.
Temperature setback becomes active when the outside temperature drops below the activation limit of temperature setback
CP17
. The full temperature setback is reached when the temperature reaches the full limit
CP16
. The actual set point will in
this case be equal to the TSET setpoint.
Temperature setback may be enabled with
CP14
.
