C2 Forced changeover setpoint
0.5°C~2°C Field settable temperature intervals between setpoints
INFORMATION
The default value of the settable temperature range (0.5°C~2°C) is 0.5°C.
A changeover from the one operation mode to the other occurs in the following
cases:
Case 1: primary changeover ( +C1)
A changeover occurs from the moment the room temperature rises above/drops
below the Cooling/Heating changeover setpoint (C1), and the guard timer has run
out.
Example:
Single setpoint
C2 24°C
+ C1 23°C
SP 22°C
+ C1
21°C
C2
20°C
The system is heating up the room.
When after a while the room
temperature rises above C1 (23°C), a
changeover from Heating to Cooling
occurs, provided that the guard timer
has run out. If the guard timer has not
run out, the changeover will only occur
from the moment the timer does run
out. As a result of the changeover, the
guard timer starts running again so as to
allow for or prevent the next
changeover.
The system is cooling down the room.
When after a while the room
temperature drops below C1 (21°C), a
changeover from Cooling to Heating
occurs, provided that the guard timer
has run out. If the guard timer has not
run out, the changeover will only occur
from the moment the timer does run
out. As a result of the changeover, the
guard timer starts running again, to
allow for or prevent the next
changeover.
Case 2: forced changeover (C2)
A changeover is forced from the moment the room temperature rises above/drops
below the Cooling/Heating forced changeover setpoint (C2) while the guard timer
is still running.
Example:
+1°C
+1°C
-1°C
-1°C
The system is heating up the room.
When after a while the room
temperature rises above C1 (25°C), a
changeover from Heating to Cooling
occurs, provided that the guard timer
has run out. If the guard timer has not
run out, the changeover will only occur
from the moment the timer does run
out. As a result of the changeover, the
guard timer starts running again so as to
allow for or prevent the next
changeover.
The system is cooling down the room.
