5. Operating modes
The RWF40... can be configured in such a way that if a Landis & Staefa Ni1000 outside
sensor (e.g. QAC22) is connected, a weather-dependent setpoint shift is implemented.
The minimum and maximum setpoint values can be set by the lower setpoint limit
«SPL» and the upper setpoint limit «SPH». Parameter «P» can be used to apply a
parallel displacement to the heating curve.
*
Each RWF40... must have its own separate outside sensor connected (no
parallel connection)!
