OMM TGZ-1 TGZ 040A through TGZ 190A 63
SET UNIT SPs (7)
Ice Time Delay=Xxsec
Clear Ice Delay=No
H.G. Delay = XX sec
H.G. Delay, hot gas bypass delay, keeps the hot gas solenoid valve closed when the first
compressor on a circuit starts. This delay allows sufficient condenser pressure to build up.
The Ice entries do not apply to TGZ units.

The pressure offsets on menus 8 and 9 and the temperature offsets on menus 10, 11 and 12
correct the controller's display. The sensors used in these units have a high degree of
repeatability but may need correction (offset). An accurate pressure gauge or thermometer
is used to determine the correct temperature or pressure. A positive or negative offset value
is then entered to make the controller reading agree with the measured value.
