SET UNIT SETPOINTS (SP)
SET UNIT SPs (1)
Unit Enable=OFF
Mode=COOL
Source=KEYPAD
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. The source for the signal is
selected in the 4
th
line and can be:
1.
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.
2.
SWITCHES, in which an external switch is wired across terminals #25 and #35. (See
wiring diagram page 27).
3.
NETWORK, used with BAS signal, which is wired to the three communication ports.
Unit Mode settings can be
1.
COOL, normal setting used with chilled water air-condition applications.
2.
COOL w/GLYCOL, used with low temperature, glycol applications. It allows a lower
LWT setpoint to be used.
3.
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.
