Alarms − system alarm codes:
1 − alarm; 0 − no alarm.
E1: breakout or short circuit of the outdoor temperature sensor. The fans are stopped.
E2: breakout or short circuit of the exhaust temperature sensor. The fans are stopped.
E3: breakout or short circuit of the return heat medium temperature sensor. The fans are stopped.
E4: breakout or short circuit of the temperature sensor for the water heater freezing protection. The fans are
stopped.
E5: breakout or short circuit of the supply air temperature sensor. The fans are stopped.
F1: heat exchanger freezing. The exhaust temperature downstream of the heat exchanger measured by the TE2
temperature sensor is below the R-02 set point within the R-03 time period when the fans are operating. The
bypass damper is fully opened. The supply and extract fans keep operating.
O1: emergency system shutdown on signal from the fire alarm panel. The fans are stopped.
P1: supply fan failure. The fans are stopped.
P2: extract fan failure. The fans are stopped.
U1: heater freezing danger. The alarm is generated if the air temperature downstream of the water heater falls
down below +3 °C.
U2: low return heat medium temperature.
This alarm is generated if the return heat medium temperature falls down below the set critical point.
In case of any of the above freezing dangers the fans are stopped, the regulating heat medium valve is 100%
opened and the circulating pump is started.
The fans may not be stopped in case of any of the freezing dangers.
The system restart is possible only after removal of the U1 alarm, i.e. after rising of the air temperature
downstream of the heater above set point, TE4 parameter, and U2 alarm, i.e. after rising of the return heat
medium temperature TE3 parameter.
U3: return heat medium temperature at the end of the water heater preheating cycle does not 40 °C
(factory setting). The fans may not be started.
U4: pump failure. No signal from the fluid pressure switch in the water heater after the signal to activate the
circulating pump. The circulating pump is deactivated and the fan operation status does not change.
U5: electric heater overheating. The air temperature downstream of the heater is above +50 °C. The electric heater
is deactivated, the fans are stopped after air supply to the heating elements.
U6: low supply air temperature. The supply air temperature measured by the TE5 temperature sensor remains below
the E-03 parameter within the E-02 time period after the unit activation. Malfunction of the electric heater. The
electric heater is deactivated, the fans are stopped.
