MENU ITEM
DEFINITION
SUPPLY AIR TEMP
This parameter gives the current value for the SUPPLY AIR
TEMPERATURE input
SUPPLY AIR TEMP ALARM SETPOINT FOR
COOLING
To enable this feature the parameter must be set to other than 0. A
value other than 0 establishes the setpoint to use in determine when
to initiate a SUPPLY AIR TEMP ALARM FOR COOLING
SUPPLY AIR TEMP ALARM SETPOINT FOR
HEATING
To enable this feature the parameter must be set to other than 0. A
value other than 0 establishes the setpoint to use in determine when
to initiate a SUPPLY AIR TEMP ALARM FOR HEATING
SUPPLY AIR TEMP LIMIT COOLING SETPOINT
This setpoint is used by the Unit Controller during ECONOMIZER
LOADING or SUPPLY AIR TEMP LIMIT mode of operation
SUPPLY AIR TEMP LIMIT FOR COOLING
ENABLE
This parameter must be turned ON to enable SUPPLY AIR TEMP
LIMIT operation in the cooling mode on a Constant Volume unit
SUPPLY AIR TEMP LIMIT FOR HEATING
ENABLED
This parameter must be turned ON to enable SUPPLY AIR TEMP
LIMIT operation in the heating mode on a Constant Volume unit
SUPPLY AIR TEMP LIMIT HEATING SETPOINT
This parameter is used by the Unit Controller during SUPPLY AIR
TEMP LIMIT FOR HEATING operation on a Constant Volume unit.
TEMPERATURE/HUMIDITY (RETURN) CONTROL
ENABLED
This parameter would be used if HOT GAS REHEAT was being used.
This feature is not available on these units. This should always be set
to OFF
THIRD PARTY BAS ECONOMIZER ENABLEd
When this parameter is turned ON the position of the economizer
damper is controlled by an external 2-10VDC input
TURN OFF CONTINUOUS FAN WHEN STARTING
HEAT
If this parameter is turned ON and the unit is running continuous fan,
the control will stop the supply fan at the start of a heating cycle and
turn it back on based on the FAN ON FOR HEAT setting
UNIT MODEL NUMBER
This allows the unit model number to be entered for the unit through
the Simplicity PC software
UNIT NAME
This allows a name to be assigned to the unit to identify it on the
network through the Simplicity PC software
UNIT SERIAL NUMBER
This allows the unit serial number to be entered for the unit through
the Simplicity PC software
UNOCCUPIED OVERRIDE TIME PERIOD
This parameter establishes the maximum time the unit will remain in
the unoccupied override mode when the override button is pushed on
the space sensor.
VAV / CV SELECTION
This parameter gives the status of the set up of the unit , VAV or CV
VAV COOLING SUPPLY AIR TEMP LOWER
SETPOINT
This parameter establishes the lower cooling setpoint for VAV cooling
operation
VAV COOLING SUPPLY AIR TEMP UPPER
SETPOINT
This parameter establishes the upper cooling setpoint for VAV cooling
operation
VAV OCCUPIED HEATING ENABLED
This parameter must be turned on to allow occupied heating
operation.
VAV OCCUPIED HEATING SETPOINT
The Unit Controller compares the space temperature to this value as
one of the criteria to use to determine when to initiate VAV Occupied
Heating Operation
VAV SUPPLY AIR TEMP RESET SETPOINT
The Unit Controller compares the space or return air temperature
to this valve to determine if it should control to the VAV COOLING
SUPPLY AIR UPPER or LOWER SETPOINT
YEAR
This parameter is used to enter the current year 0 to 99. For example
7 would be 2007
