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:
• Compressor 1
• Compressor 2
• Condenser Fan 1
• Condenser Fan 2
• Supply Fan
• Electric Heat Stage 1
• Electric Heat Stage 2
• Filter (Runtime only)
• Gas Heat Stage 1
• Gas Heat Stage 2
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
Three diagnostics 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:
• 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.
After the 15 minute compressor proving timeout has expired, if the unit is not under a “Diagnostic:
Compressor 1 Proving Lockout” event
• The Diagnostic: Comp X Proving Trip diagnostic is reset
• If the cooling stage is still requested ON, the circuit is allowed to stage again
Diagnostic: Compressor X Proving Lockout
There are two cases that can cause a Diagnostic: Compressor X Proving Lockout:
• 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.
Note: 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.
If a Diagnostic: Compressor X Proving Lockout is generated the following will occur:
