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 COOL-
ING 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 HEAT-
ING SETUP tab in the Simplicity PC software
package.
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 first
compressor from System 1 and turn on a 5 minute
timer.
– If after 5 minutes the space temperature is be-
tween 1.5° F and 1.9° F above the “CV OCCU-
PIED COOLING SETPOINT” or “CV UNOC-
CUPIED 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 COOLING
SETPOINT” or “CV UNOCCUPIED COOLING
SETPOINT” the control will bring on the first
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 OCCU-
PIED COOLING SETPOINT” or “CV UNOC-
CUPIED COOLING SETPOINT” the control will
bring on the first 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 first compressor of System 2 and start a 3 min -
ute 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.
The Simplicity Control will stage off the cooling as
follows:
• If the space temperature is within 0.5° F of the
“CV OCCUPIED COOLING SETPOINT”
or
“CV UNOCCUPIED COOLING SETPOINT”
the control turns off the System 2 compressors, if
ON, with a 30 second delay between the compres-
sors provided the minimum compressor run times
have been satisfied.
• If the space temperature is equal to or below the
“CV OCCUPIED COOLING SETPOINT” or
“CV UNOCCUPIED COOLING SETPOINT” the
control turns off the System 1 compressors with
a 30 second delay between the compressors pro-
vided the minimum compressor run times have
been satisfied.
The Simplicity Control has the following timing cool-
ing functions:
• Minimum off time of 5 minutes.
• Minimum ON time of 3 minutes – This parameter
can be programmed from between 1 and 10 min-
utes using the COOLING SETUP tab of the in the
Simplicity PC software package.
