I.1.11 Set-point Compensation
The Set-point c ompensati on func tion on the basis of the outdoor
temperature c arries out the algebra s um between the Set-point value
set and an offs et value calcul ated depending on the temperature of the
outdoor air. It is possibl e to decide whether to acti vate the func tion in
both functioning modes (summer/winter) or onl y in one.
This func tion is not availabl e if the Scrolling Set-point (CS) functi on is
enabled.
Press the Prg key for 2 s econds to access it.
Press the MODE key until the following mas ks are displ ayed:

Press the Prg key for 2 seconds .
Modify the Y parameter ( yes) to enable the function.
Press the MODE and ON/OFF keys at the s ame ti me to memorise the
val ue s et.
For setting in winter mode, proceed as i ndicated for the s ummer mode.
To return to the initial screen, press the MODE and ON/OFF keys at the
same time.
I.1.12 Integrativ e resistance (KRIT)
The el ectric resistance (KRIT access ory) acts as integration i n winter
mode (onl y on machi ne i n heat pump mode). If enabl ed, this func tion
allows to manage the integrative resistance. The integrative resistance
can be managed on the basis of the outdoor air temperature. In this
case the presence of a probe is necess ary (KEAP acc essor y).
The integrative resistanc e function based on the temperature of the
outdoor air is not available if the Scrolling Set-point (CS) functi on is
enabled.
