Service Tests
The Service Test menu provides access to screens used to
change certain operating parameters from “Auto” mode to
manual mode. A manual mode control signal overrides
specific auto control functions. Tests and status screens
provide a means to check the operation of some output
and input devices.
Anytime a manual mode is selected the alarm light will
remain on.
Normal machine operation does not require the use of any
service test menus; therefore they remain within a
password-protected menu. Manual operation of these
items will affect chiller operation and will cause unreliable
operation, if left in manual mode. Therefore, we
recommend that only qualified personnel use service tests.
