Calculated CH setpoint based on outdoor reset curve.
5.2.1.3 CH mode 2 – Central Heating with full outdoor temperature reset
When CH_Mode is set to 2, full weather compensator is chosen. For this mode an outdoor sensor has to be connected.
The
CH_Setpoint is calculated on the same way as described in paragraph”5.2.1.2 CH mode 1 - CH with an outdoor temperature reset and thermostat
control” pag. 28.
The
CH_Setpoint can be calculated with an extra correction described in paragraph “5.2.1.2 CH mode 1 - CH with an outdoor temperature reset and
thermostat control” pag. 28
However, the demand does not depend on the RT input but on the outdoor temperature and the outdoor reset setpoint.
When the outdoor temperature is below
Warm_Weather_Shutdown (settable) CH demand is created.
During the night an input signal from an external clock can lower the
CH_Setpoint .
When the RT input opens
CH_Setpoint will be decreased with Night_Setback_Temp .
The RT input does not inuence the CH demand directly!
