-40-60°C
24°C (76°F)
CP 02
Minimum set point limit in cooling mode
-40-60°C

Controls Configuration
CP 04
Economy (unoccupied) Mode temperature shift:
The comfort (occupied) setpoint is shifted by the value set with
parameter. If heating is active the comfort setpoint will be
decreased, if cooling is active, the setpoint will be increased.
(Enable with UP06.)
0-10.0°C
5°C (10°F)
CP 05
Dead Zone Span:
The Dead Zone Span lies between the heating and the cooling
setpoint. The output is off while the temperature is within the dead
zone span. A negative dead zone is not possible.
0-100°C
1.0°C (2°F)
CP 06
Heat/Cool Changeover Delay (if set to CP12 = 4):
A demand to switch between heating and cooling must persist for
the length of time set with this parameter before the controller
switches. Prevents activation of a sequence during a short-term
change in temperature in order to protect equipment (with control
overshoot for example)

Switching Hysteresis
is the difference between switching on and switching off. A small
hysteresis will increase the number of switching cycles and thus
the wear on associated equipment.
0-10.0°C
0.5°C (1°F)
CP 10
Delay OFF (Minimum running time),
The minimum time the output is running once it switches on.
0…255 s

CP 11
Delay ON (Minimum stopping time)
The minimum time the output is off, once it switches off.
0…255 s

CP 12
Control option:
0 = Cooling only
1 = Heating only
2 = 2-pipe system: No demand based heat – cool switching
3 = 4-pipe system: Demand based heat – cool switching

Default = 3
W01 = 0
W02 = 1
W03 = 2
W04 = 3
Proportional control
(P-band)
The proportional control function calculates the output based on the difference between setpoint and measured
value. The proportional band (P-band) defines the difference between setpoint and measured value which will
result in a 100% output. For example, with a heating or reverse 0-10v control sequence, and a 2.0°C (4.0°F) P-
band value, at 10v the controller will be 2.0°C (4.0°F) below setpoint. This is the working range of the
proportional control sequence.
Setting the proportional band to 0 disables proportional control.
