62 TGZ 040A through TGZ 190A OMM TGZ-1
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 on page 16).
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, is not an option with TGZ Templifiers.
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.
