Use Controller's Version, Component Check Features for Diagnostics
Two features in the controller make checking on the presence and performance of components in the network
easy. Navigating to the soft ware version window allows temperature comparison between the ATO and the tem-
perature probe. A dramatic diff erence indicates a probe problem or an oil level problem.
Navigating to the Component Check window, allows relays to be opened/closed, latch relays to be checked,
blower motors to be run.
Use Soft ware Display for Diagnostics
• Press the Home button
• Press the Question Mark button.
• Press the down arrow to navigate to the
Software version icon.
• Press the software icon.
• Press the down arrow to scroll the software
versions for each component: SIB, FIB,
VIB, SUI, OQS, etc.
• The numbers should match current version
numbers.
• The absence of numbers or the presence
of all zeros in a component fi eld means
that component is not being seen on the
network.
• Scroll with the down arrow again to the
temperature display for the ATO and the
temperature probe.
• The numbers should be very close. A big
difference indicates a probe issue or an oil
level problem.
Use Error Codes to Track Problems
• Press Home button.
• Press Service button.
• Press Manager button.
• Enter 1656
• Press check mark.
• Scroll recorded error codes with up and
down arrow keys.
• The codes are displayed, in the order they
were recorded, in windows of three.
• There's a video guide to responding to error
codes included on the fl ash drive.
• Error codes can point to operational issues,
such as failure to fi lter, that lead to required
maintenance.
