• 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 o. 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.

H.G. Delay, hot gas bypass delay, keeps the hot gas solenoid
valve closed when the rst compressor on a
circuit starts. This delay allows sucient condenser pressure to
build up.
