P5 AC Heat curve minimum outside temperature °C
This sets the minimum outside temperature at which one wants the maximum flow temperature that is set.
P5 AD Heat curve flow temperature at minimum °C
This sets the desired maximum flow temperature at the set minimum outside temperature.
P5 AE Heat curve maximum outside temperature °C
This sets the maximum outside temperature at which one wants the minimum flow temperature that is set.
P5 AF Heat curve flow temperature at maximum °C
This sets the desired minimum flow temperature at the set maximum outside temperature.
P6 BC Heat curve Parallel Shift °C
The heating curve is set by the parameters. Next to these setting done by the installer, the end user has the free-
dom to influence the flow temperature by doing a parallel shift setting. In this parameter the margins are set within
which the user can increase and decrease the calculated flow temperature relative to the calculated flow tempera-
ture by the heating curve that is set.
The actual parallel shift that is set by the user within the bandwidth allowed according to “P5AQ Max Heat curve
Parallel Shift”.
