Active Setpoint
This is the setpoint temperature to which the control is set
when operating in the Constant Setpoint, Remote Setpoint or
Outdoor Reset Mode. When in the Constant Setpoint Mode,
this value is equal to the Internal Setpoint setting in the
Configuration Menu. When in the Remote Setpoint Mode, this
value is the setpoint equivalent to the remote analog signal
supplied to the unit. When in the Outdoor Reset Mode, this is
the derived value from the charts in Appendix E.
