Determining Cooling Status
Clg Status is a status item which indicates whether or not
mechanical cooling is currently allowed. If cooling is disabled,
the reason is indicated.
The following are descriptions of cooling status states.
Enabled
Mechanical cooling is enabled if all the following are true:
• Cooling capability is provided
• Control mode is not set via the keypad to fan only or heat
only
• Control mode is set via the keypad to auto and not
disabled via a network command
• The outdoor air temperature (OAT) on air cooled units or
the entering water temperature (EWT) on water cooled
units is high enough for operation
• Compressor operation is not disabled by an alarm
condition
None
Cooling capability is not provided.
Off Ambient
The outdoor air temperature (OAT) on air cooled units or the
entering water temperature (EWT) on water cooled units is too
low for operation.
The OAT becomes too low for operation when it drops below
the OAT cooling lockout setting. OAT becomes high enough for
operation when it rises above the OAT cooling lockout setting
by more than 2°F (adjustable - OAT Diff). The EWT becomes
too low for operation when it drops below the minimum EWT
set point. EWT becomes high enough for operation when it
rises above the minimum EWT set point by more than 2°F
(adjustable - Econo Diff).
NOTE: The OAT cooling lockout cannot be set lower than
40°F when the unit is equipped with an evaporative
condenser and should not be set lower than 50°F
unless the unit is equipped with low ambient
capability.
Off Alarm
Compressor operation is disabled by an alarm condition. This
happens when either all circuits are disabled by either a high
or low pressure alarm, when applicable the water ow switch
alarm is active, when applicable sump pump fail alarm is active
or applicable water regulating valve alarm is active.
Off Network
Control mode is set via the keypad to auto and cooling is
disabled via a network command.
Off Manual
Control mode is set to Fan Only or Heat Only via the keypad
display.
Determining Heat Status
Htg Status is a status item which indicates whether or not
heating is currently allowed. If heating is disabled, the reason
is indicated.
The following are descriptions of heating status states:
Enabled
Heating is enabled if all the following are true:
• Heating capability is provided
• Control mode is not set via the keypad to fan only or cool
only
• Control mode is set via the keypad to auto and not
disabled via a network command
• The outdoor air temperature (OAT) is low enough for
operation
None
Heating capability is not provided.
Off Ambient
The OAT is too high for operation. The OAT becomes too
high for operation when the OAT rises above the OAT heating
lockout set point. OAT becomes low enough for operation
when the OAT drops below the OAT heating lockout set point
by more than the Heating Lockout Differential.
Off Network
Control mode is set via the keypad to auto and the unit is
disabled via a network command.
Off Manual
Control mode is set to Fan Only or Cool Only via the keypad.
