The application programmes RAMSES 718 P/S
RAMSES 718 P / RAMSES 718 S 22
RAMSES 718 S:
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 a set base set point and not to the actual set point
Object 12: Outdoor temperature compensation / adjust set point
The function of the object is defined by the parameter set point correction at high outside
temperature.

Receive only
Receives set point correction for outdoor
temperature compensation.
Receive
Calculate internally and
send
Reports the current set point correction as an
amount or as a differential.
The format of the correction value (see following
table) is set on the set point adjustment parameter
page.

Object function Example
Absolute
Sends the amount:
base set point without correction
+ set point correction as set point
for other temperature controllers.
Unadjusted base set point = 20 ºC. set
point correction = +2 K
The object transmits: 22 ºC
Relative
Calculated set point correction
(in Kelvin) based on the outside
temperature.
Unadjusted base set point = 20 ºC. set
point correction = +2 K
The object sends: 2 K
