Description
Not used
No function.
External / return
air temperature
Sensor input for external room temperature sensor or
return air temperature sensor to acquire the current
room temperature, or floor heating temperature
sensor to limit the heating output.
Note: The room temperatu
re is acquired by the built
sensor if the floor temperature limitation function is
enabled via parameter P51.
Heating /
cooling
changeover
Sensor input for "Automatic heating /
changeover" function.
A switch can also be connected rather than a sensor
Important: Switch closed means always cooling, (this
cannot be changed), see section 3.5
.
Heating / cooling changeover is also possible via bus.
In
this case, the function must not be assigned to any
local input X1, X2. See also section

Operating mode switchover is also possible via bus.
In this case, the function must not be assigned to any
