W1 – First Stage of Heating
•
W2 – Second Stage of Heating
•
W3 – Third Stage of Heating
See the Heating section of this manual for a description
of the heating staging.
of the heating staging.
Unoccupied Heating
Unoccupied heating operation is the same as Occupied.
A programmable thermostat would be required in order
to change the heating temperature settings between
occupied and unoccupied.

Cooling Operation – Occupied or Unoccupied
The Simplicity Control will stage on the cooling as
follows:

•
At cooling start up
– If the space temperature is between 1.5° F and
1.9° F above the “CV OCCUPIED COOLING
SETPOINT” or “CV UNOCCUPIED COOL-
ING SETPOINT” the control will turn on the
fi rst compressor from System 1 and turn on a
5 minute timer.

– If after 5 minutes the space temperature is
between 1.5° F and 1.9° F above the “CV
OCCUPIED COOLING SETPOINT” or “CV

OR
– If the space temperature is greater than 2.0° F
or more above the “CV OCCUPIED COOL-
ING SETPOINT” or “CV UNOCCUPIED
