Diagnostics

Device Tracker

Symbio 700 will keep statistical data of the unit for component starts and component run times
(in hours) for the following unit components:
•
•
•
•
•
•
•
•
If the Filter Runtime hours exceed the value set by the user for the Filter Runtime Hours Setpoint,
the Symbio 700 controller activates the Diagnostic: Maintenance Required point.
If for any reason it is required to reset the component statistical data, the Run Time Reset or
Starts Reset points can be accessed through the Symbio Service and Installation mobile app.. If
the reset points are set to Reset, the Component Run Time and Starts are reset to 0 and the
associated reset points are set back to inactive. In the case of the Diagnostic: Maintenance
Required point, it will also be reset to Inactive if Filter Timer Reset point is set.

Compressor Proving Diagnostics

There are three diagnostics that can be generated based on the compressor proving input.

Diagnostic: Compressor X Proving Trip

When a compressor output is commanded ON and it has been running for more than 5 seconds,
if the associated proving input opens, the controls generate the Diagnostic: Comp X Proving Trip
and the following will occur:
•
•
•
After the 15 minute compressor proving timeout has expired, if the unit is not under a
"Diagnostic: Compressor 1 Proving Lockout" event
•
•

Diagnostic: Compressor X Proving Lockout

There are two cases that can cause a Diagnostic: Compressor X Proving Lockout:
•
•
If a Diagnostic: Compressor X Proving Lockout is generated the following will occur:
•
ACC-APG001A-EN
Compressor 1
Compressor 2
Condenser Fan 1
Condenser Fan 2
Supply Fan
Electric Heat Stage 1
Electric Heat Stage 2
Filter (Runtime only)
Command the associated compressor output OFF immediately.
Command any compressor output OFF that is on the same refrigeration circuit as the
compressor which had the proving input trip.
The Circuit is disabled for 15 minutes.
The Diagnostic: Comp X Proving Trip diagnostic is reset
If the cooling stage is still requested ON, the circuit is allowed to stage again
If a refrigeration circuit accumulates 4 consecutive Diagnostic: Comp X Proving Trips during
the same compressor operating cycle, a Diagnostic: Compressor X Proving Lockout is
generated.
N N o o t t e e : : If the call for the compressor operation terminates, the counter is set to zero.
If a compressor's associated proving input does not CLOSE within 5 seconds of the
compressor startup.
All compressors on the associated circuit are de-energized immediately and they are locked
out until a Reset Diagnostic action is initiated.
