Setpoint limits
Parameter Description
Range
Default
CP 00
Minimum set point limit in heating mode
-40-60°C
16°C (61°F)
CP 01
Maximum set point limit in heating mode
-40-60°C
30°C (87°F)
CP 02
Minimum set point limit in cooling mode
-40-60°C
16°C (61°F)
CP 03
Maximum set point limit in cooling mode
-40-60°C
30°C (87°F)
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 = 3):
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).
0…255 min
5 min
CP 07
Min. temperature difference required to start free heating
0-10.0°C
1.0°C (2.0°F)
CP 08
Min. temperature difference required to start free cooling
0-10.0°C
1.0°C (2.0°F)
CP 09
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 damper is open
0…255 s
200s
CP 11
Delay ON (minimum stopping time)
The minimum time the damper is closed.
0…255 s
200s
CP 12
Control option:
0 = Cooling only
1 = Heating only
2 = Manual heat – cool switching
3 = Demand based heat – cool switching
0…3
Default = 3
W01 = 0
W02 = 1
W03 = 2
W04 = 3
Control logicfree cooling
If the room temperature is above the setpoint, the controller will open the outside damper if the outdoor
temperature is below the room temperature with a minimum difference as specified under CP08.
Once the outdoor damper is open, it will stay open until the setpoint is reached or outdoor temperature is higher
than room temperature.
If the outdoor damper closed because the setpoint is reached, it will re-open after the indoor temperature
increased for the amount specified under hysteresis CP09.
Control logicfree heating
If the room temperature is below the setpoint, the controller will open the outside damper if the outdoor
temperature is above the room temperature with a minimum difference as specified under CP07.
Once the outdoor damper is open, it will stay open until the setpoint is reached or outdoor temperature is lower
than room temperature.
If the outdoor damper closed because the setpoint is reached, it will re-open after the indoor temperature
decreased for the amount specified under hysteresis CP09.
