Occupied Heating

There are three stages of heating available:
•
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.

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.
Space Sensor – Hard Wired or Communicated
The following System Parameters must be programmed
through the Simplicity Control:
•
"CV OCCUPIED COOLING SETPOINT" – us-
ing Parameter 10 under the PROGRAM key on
the Simplicity control board or under the COOL-
ING SETUP tab in the Simplicity PC software
package.
•
"CV OCCUPIED HEATING SETPOINT" – us-
ing Parameter 11 under the PROGRAM key on
the Simplicity control board or under the HEAT-
ING SETUP tab in the Simplicity PC software
package.
•
"CV UNOCCUPIED COOLING SETPOINT"
– using Parameter 12 under the PROGRAM
key on the Simplicity control board or under
the COOLING SETUP tab in the Simplicity PC
software package.
•
"CV UNOCCUPIED HEATING SETPOINT"
– using Parameter 13 under the PROGRAM
key on the Simplicity control board or under
the HEATING SETUP tab in the Simplicity PC
software package.
JOHNSON CONTROLS
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
UNOCCUPIED COOLING SETPOINT" the
control will bring on the second compressor
of System 1 and start a 5-minute timer.
OR
– If the space temperature is greater than 2.0° F
or more above the "CV OCCUPIED COOL-
ING SETPOINT" or "CV UNOCCUPIED
COOLING SETPOINT" the control will bring
on the fi rst compressor from System 1 and
start a 3 minute timer. After 30 seconds, the
control will bring on the second compressor
from System 1.
•
If after 3 or 5 minutes the space temperature is
between 1.5° F and 1.9° F above the "CV OC-
CUPIED COOLING SETPOINT" or "CV UN-
OCCUPIED COOLING SETPOINT" the control
will bring on the fi rst compressor from System 2
and start a 5 minute timer.
•
If after 3 or 5 minutes the space temperature
is 2.0° F or more above the "CV OCCUPIED
COOLING SETPOINT" or "CV UNOCCUPIED
COOLING SETPOINT" the control will bring
on the fi rst compressor of System 2 and start a 3
minute timer.
•
If after 3 or 5 minutes the space temperature
is 1.5° F or more above the "CV OCCUPIED
COOLING SETPOINT" or "CV UNOCCUPIED
COOLING SETPOINT" the control will bring on
the second compressor of System 2.
