Unit Enable settings can be OFF and ON as determined from the Unit Enable setpoint.
Unit Enable is an external signal or a keypad setting that keeps the unit off when the setting is OFF and
allows it to run if there is a call for cooling when the setting is ON. The source for the signal is selected
in the 4
th
line and can be:
•
KEYPAD, in which case the selection is made in line 2 and would be normally selected as ON. This
is the normal setting when no external signals are controlling the unit.
•
SWITCHES, in which an external switch is wired across terminals #40 and #53. (See wiring diagram
page 8 or 9.)
•
NETWORK, used with BAS signal, which is wired to the three communication ports.
•
Unit Mode settings can be
•
COOL, normal setting used with chilled water air-condition applications.
•
COOL w/GLYCOL, used with low temperature, glycol applications. It allows a lower LWT setpoint
to be used.
•
ICE w/GLYCOL, used with ice storage systems, allows changing from chilled glycol operation to
lower temperature ICE operation. In ICE, the unit runs at full load until the ICE setpoint is reached,
at which time the unit shuts off. A three-position switch wired to terminals #28 and #38 initiates the
change from glycol cooling to making ice. (See wiring diagrams on page 8 or 9.)
Unit Mode settings can be COOL COOLw/Glycol, or ICEw/Glycol, as determined from the Unit Mode
setpoint.
Source settings can be KEYPAD, SWITCHES, or NETWORK as determined from the Mode Source
setpoint.
