ALARMS System alarm codes. Failure (1) or no failure (0)
Е1
Breakdown or short circuit of the intake air temperature sensor. Both
fans are stopped.
Е2
Breakdown or short circuit of the exhaust air temperature sensor. Both
fans are stopped.
Е3
Breakdown or short circuit of the return heat medium sensor. Both
fans are stopped.
Е5
Breakdown or short circuit of the supply air temperature sensor. Both
fans are stopped.
F1
F1 alarm (heat exchanger freezing) appears if exhaust air temperature
remains below R-02 parameter within R-03 time period, refer heat
exchanger adjustments Adjust-Recuper. In case of this alarm the
bypass damper is fully opened and the supply and extract fans keep
operating.
О1
Emergency system shutdown on the signal from fire fighting system.
Both fans are stopped.
U1
U1 alarm (water heating coils danger) appears if air temperature
downstream from the water heating coils drops below the minimum
set level +3 ºС.
U2
Alarm U2 (low return heat medium temperature) appears if the return
heat medium temperature drops below the set critical set point Q-04.
In case of any freezing danger alarms both fans are stopped, the
heat medium regulating valve is 100% opened and the circulation
pump turns on. Start-up of the fans at any freezing danger alarms is
disabled. The system can be restarted only after the above alarms are
no longer imminent, i.e. after the temperature of return heat medium
TE3 (for U2 alarm) and the air temperature at outlet from the water
heating coils (for U1 alarm) increases above the set point to prevent
the heating coils freezing.
