Weather-Dependent Setpoint Shift - Siemens RWF40.000A97 User Manual

5.5 Weather-dependent setpoint shift

Parallel displacement of
heating curve
HVAC Products
The RWF40... can be configured such that if an outside sensor with an LG-Ni1000
sensing element (e.g. QAC22) is used, a weather-dependent setpoint shift will be
implemented. The minimum and maximum setpoint values can be set by the lower
setpoint limit «SPL» and the upper setpoint limit «SPH». In addition, with the
RWF40.0X2B97, the lower working range limit «oLLo» and the upper working range
limit «oLHi» protect the plant by ensuring that the minimum plant temperature will be
observed. Parameter «P» can be used to apply a parallel displacement to the heating
curve.
G
Each RWF40... must have its own separate outside sensor (no parallel
connection)!
F
This function has been optimized for space heating combined with domestic hot
water heating.
