SECTION 7 – PARAMETER DESCRIPTIONS AND OPTIONS
MENU ITEM DEFINITION
DATA LOG FORMAT
This parameter is set through the Service key and is used to initiate the data
logging feature. The options are Off, Uncompressed, Skip Unchanged.
DE MODIFIER ADDRESS
This parameter is programmed through the Service key. The default value is 230
which results in a DE Instance number of 23000 plus the MAC address. This is
the YORK default value. If it is set to -1 all communication is disabled.
DE MODIFIER OFFSET
This parameter is programmed through the Service key. The default value is -1.
The DE Instance number can be set manually using the DE Modier Address
and this parameter.
DEW POINT RESET
This parameter is programmed through the PROGRAM key. This function
changes the Active Supply Air Temperature to a lower value when the air be-
neath the oor of a FlexSys unit approaches the dew point temperature of the
air. The choices are Enabled or Disabled.
DIG COMP LOAD PT 1
This is the lowest capacity the digital compressor (A) can operate at. The default
value is 33%
DIG COMP LOAD PT2
This is the middle capacity the digital compressor (A) can operate at. The de-
fault value is 67%
DIG COMP LOAD PT 3
This is the maximum capacity the digital compressor (A) can operate at. The
default value is 100%
DISCHARGE PRESSURE MINIMUM
This parameter identies the lowest discharge pressure of all the active com-
pressors.
DISCHARGE PRESSURE SETPOINT
This parameter is programmed through the SETPOINTS key and is the dis-
charge pressure the Unit Controller tries to maintain by adjusting the condenser
water ow.
DISCHARGE PRESSURE SP Min
This parameter is programmed through the SETPOINTS key and is the mini-
mum discharge pressure the unit controller tries to maintain by modulating the
condenser water ow.
DISCHARGE PRESSURE SP Max
This parameter is programmed through the SETPOINTS key and is the maxi-
mum discharge pressure the unit controller tries to maintain by modulating the
condenser water ow.
DISPLAY LANGUAGE
This parameter is programmed through the PROGRAM key. This allows the
user to select the language the Primary Unit Controller uses to display the infor-
mation at the User Interface. The choices are English or Spanish.
DISPLAY UNITS
This parameter is programmed through the PROGRAM key. This allows the user
to select which unit of measure the Primary Unit Controller uses to display the
information at the User Interface. The choices are Imperial, SI, or SI Canada.
DUCT PRESS CNTRL
This parameter is set through the PROGRAM key and is used to specify the
type of pressure control to use when the unit is programmed for two duct static
pressure transducers. The options are duct press 1 only, highest, lowest and
average.
DUCT PRESS SENSOR 2
This parameter is set through the OPTIONS key and is used to identify when
two duct static transducer have been installed. The options are Not Installed or
Installed.
DUCT PRESS TRANSDUCER SPAN
This parameter is programmed through the SETPOINTS key. This allows the
use of three different duct pressure control ranges, 0 to 1.00 IN-WG, 0 to 2.50
IN-WG, or 0 to 5.00 IN-WG.
DUCT STATIC OVER PRES
This parameter is programmed through the Setpoints key. This sets the maxi-
mum allowable Duct Static value before the Primary Unit Controller lockouts the
unit on an over pressure fault.
DUCT STATIC PRES CURRENT 1
This is the actual duct static pressure sensed by static pressure transducer 1
when the Unit Controller is programmed for two duct static inputs.
