A7: Compressor discharge temperature (measured by sensor A3) over limit (limit set by parameter F58 – default
setting 230’F). Check the following:
1. If the water set temp (F11) is above 125’F, reduce it to 125’F temporarily.
2. If the ambient temperature is close to the high ambient temperature operating limit, switch to Heater mode
temporarily. Revert to Auto or Econ mode when ambient temperature has normalized.
3. If the alarm is still not resolved, follow these steps and report findings to AirGenerate support.
a. Deactivate alarm & let the unit run in Econ mode (to de-activate A7 alarm, set parameter F57 to zero)
b. Check amperage (place a clamp meter around one of the live/hot wires)
c. Check exhaust temperature
d. Check evaporator coil temperature (A2) by pressing the ‘Down’ arrow button
e. Check compressor discharge temperature (A3) by pressing ‘Up’ and ‘Down’ arrow keys together.
IMPORTANT: Do not run the unit for more than 15 minutes in Econ mode. After taking these readings,
switch to Heater mode again. Re-activate alarm A7 by setting parameter F57 to 1.
f. If AirGenerate support recommends a refrigerant recharge, follow ‘Refrigerant Recharge’ procedure.
AirGenerate support may also request that additional troubleshooting measures or temperature readings be
taken.
A8: Condensate drain blockade alarm. Turn the unit off and check condensate drain/hose to ensure condensate wa-
ter is draining properly. Re-start unit.
