Quick Test (Service Test) — Main power and control
circuit power must be on for Quick Test. The Touch Pilot™
Quick Test function is used to verify proper operation of vari-
ous devices within the chiller, such as condenser fans, automat-
ed isolation valves, EXVs, and remote alarm relays. This is
helpful during the start-up procedure to determine if devices
are installed correctly.
To use the Quick Test mode, the Enable/Off/Remote Con-
tact switch must be in the OFF position. To reach the Quick
Test menu, follow the path: Main Menu Quick Test Table.
The unit must be in Local Off mode to adjust parameters in the
table. The Quick Test function is not available remotely, and
can only be used from the Touch Pilot display. See the Start-Up
Checklist at the end of this document, page CL-6, for a list of
the parameters in the Quick Test Table.
