CH Setpoint calculated with an extra correction
The calculated setpoint based on the outdoor temperature can also be adjusted with another correction. The generation of this
extra correction is a result of a not linear computation.
The new setpoint is calculated as follow:
New CH calculated setpoint (@Outdoor_temp)= CH calculated setpoint (@Outdoor_temp) – extra correction (@Outdoor_temp)
The parameter used for the extra compensation is E2_CH_Reset_Curve_Comp .
