2452.0 Start hysteresis, cooling, heating/cooling circuit 1
Only in conjunction with a room temperature sensor
(extended cooling mode): Start hysteresis for room
temperature-dependent cooling mode via heating/cool-
ing circuit 1
If the room temperature exceeds the set room temper-
ature by the set temperature differential, cooling is
switched on.
2452.1 Stop hysteresis, cooling, heating/cooling circuit 1
Only in conjunction with a room temperature sensor
(extended cooling mode): Stop hysteresis for room
temperature-dependent cooling mode via heating/cool-
ing circuit 1
If the room temperature falls below the set room tem-
perature by the set temperature differential, cooling is
switched off.
2453 Room temperature limit for cooling, heating/cooling circuit 2
2453.0 Start hysteresis, cooling, heating/cooling circuit 2
Only in conjunction with a room temperature sensor
(extended cooling mode): Start hysteresis for room
temperature-dependent cooling mode via heating/cool-
ing circuit 2
If the room temperature exceeds the set room temper-
ature by the set temperature differential, cooling is
switched on.
2453.1 Stop hysteresis, cooling, heating/cooling circuit 2

(extended cooling mode): Stop hysteresis for room
temperature-dependent cooling mode via heating/cool-
ing circuit 2
If the room temperature falls below the set room tem-
perature by the set temperature differential, cooling is

2454.0 Start hysteresis, cooling, heating/cooling circuit 3
Only in conjunction with a room temperature sensor
(extended cooling mode): Start hysteresis for room
temperature-dependent cooling mode via heating/cool-
ing circuit 3

ature by the set temperature differential, cooling is
switched on.
