Heating Operation - Occupied Or Unoccupied; Stand Alone - York ECO2 YPAL 050 Installation & Operation Manual

Sequence of Operation
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 com-
pressors provided the minimum compressor run
times have been satisfi ed.
•
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
provided the minimum compressor run times
have been satisfi ed.
The Simplicity Control has the following timing cooling
functions:
•
Minimum off time of 5 minutes.
•
Minimum on time of 3 minutes – This param-
eter can be programmed from between 1 and 10
minutes using the COOLING SETUP tab of the
in the Simplicity PC software package.
Heating Operation – Occupied or Unoccupied
The Simplicity Control will stage on the heat as
follows:
•
When the space temperature is 1.5° F – 1.9° F
below the "CV OCCUPIED HEATING" or "CV
UNOCCUPIED HEATING SETPOINT" the
control energizes the fi rst stage of heat.
•
When the space temperature is 2.0° F – 2.4° F
below the "CV OCCUPIED HEATING" or "CV
UNOCCUPIED HEATING SETPOINT" the
control energizes the second stage of heat.
•
When the space temperature is 2.5° F or more
below the "CV OCCUPIED HEATING" or "CV
UNOCCUPIED HEATING SETPOINT" the
control energizes the third stage of heat.

The Simplicity Control will stage off the heat as
follows:
•
When the space temperature is 2.4° F below the
"CV OCCUPIED HEATING" or "CV UNOC-
CUPIED HEATING SETPOINT" the third stage
of heating will turn off.
•
When the space temperature is 1.9° F below the
"CV OCCUPIED HEATING" or "CV UNOC-
CUPIED HEATING SETPOINT" the second
stage of heat will turn off.
•
When the space temperature is 0.1° F above the
"CV OCCUPIED HEATING" or "CV UNOC-
CUPIED HEATING SETPOINT" the fi rst stage
of heating will turn off.
The Simplicity Control has the following heating timing
functions:
•
A minimum off time of 2 minutes.
•
A minimum on time of 3 minutes.
•
There is a 30 second time delay between stag-
es.

Stand Alone

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.
