The Heat Pump Controller can use the internal time clock for
a setting an occupied schedule, for this the setpoint will be 0.
It can also be programmed to follow an external schedule
command. You must have an OSS Optimal Start Scheduler
installed somewhere on you communications loop to provide
the external schedule, and you select the schedule number
here.
If you entered the same starting time for several heat pumps,
they are prevented from all starting their fans at the same
time by a Startup Delay Period that is determined by their
address switch setting. The address is multiplied by the
number of seconds you enter on this screen, up to a
maximum of 60 seconds per address. This is the time period
the fan must wait before it starts when the schedule goes
occupied.
If you entered 5 seconds and the address was 10 then the fan
would start 5 x 10 or 50 seconds after the schedule goes
occupied.

An Energy Demand Limit sequence is programmed into all
heat pump controllers. It is currently an option that is not
supported by a controller that can send the Demand Limit
signal to initiate a limiting condition. It is included here for
future use only.
