4.3.2 Objects for the room temperature controller (RTC)
Object 10: Base set point
RAMSES 718 P: The function of the object is determined using the parameter function of the
rotary control.
Parameter: Rotary
control function
Base set point
Manual offset or blocked Receives the base set point from the bus.
RAMSES 718 S:
Receives the base set point from the bus.
The base set point is first specified via the application at start-up and stored in the base set
point object.
Then it can be re-determined at any time with this object (limited by minimum or maximum
valid target value).
Object 11: Manual set point offset / set point offset at rotary control
RAMSES 718 P: The function of the object is determined using the parameter function of the
rotary control

RAMSES 718 P / RAMSES 718 S
Object function
Sends the base set point set at the rotary control.
The base set point is first specified via the application at start-up
and stored in the base set point object.
Afterwards, it can be specified again at any time this object (limited
by the minimum or maximum valid set point).
Object function
Receive manual set point offset.
The object receives a temperature difference.
The desired room temperature (current set point) can be
adjusted against the base set point by this difference.
This applies in comfort mode (heating):
Actual set point = base set point + manual set point offset.
Values outside the configured range are limited to the highest
or lowest value.
If a 0 is received, a set point temperature offset that was
previously entered is reset to 0.

The offset always refers to the set base set point and
not to the current set point.
Sends the set point offset set at the rotary control.
