Line 2 Current Heating or Cooling Demand
Based on the comparison between the current HVAC Mode
Enable Temperature and the HVAC Mode Heating or
Cooling Setpoint Temperatures. This number is calculated
by subtracting the HVAC Mode Enable Temperature from
either the HVAC Mode Enable Heating Or HVAC Mode
Enable Cooling Setpoint values (depending on which Mode
is currently active ) to arrive at this value. A positive
number indicates a Cooling demand and a negative number
indicates a Heating demand.
