ERROR CODE DESCRIPTION
Error code
Heater type
ELECTRIC
WATER
TE1, ТЕ2
Break of the sensor positive wire, short circuit of sensor output, malfunction or absence of the temperature sensor.
TE3, ТЕ4
Break of the sensor positive wire, short circuit of sensor
output, malfunction or absence of the temperature sensor.
ТЕ5
Break of the sensor positive wire, short circuit of sensor output, malfunction or absence of the temperature sensor.
DI1
Triggering of the TK-60 thermal switch (the air
temperature in the heating area e60 °C).
Normally closed contact, self-resetting.
DI2
Actuation of fire detector or short circuit in the sensor circuit. Normally opened contact.
DI3
Triggering of the TK-90 thermal switch (the air
temperature in the heating area e90 °C).
Normally closed contact with manual reset. To reset,
press the button on the sensor (for the units with electric
heaters).
DI5
No water pressure. Used for connection control of the
NKP or NKD electric heaters to the unit. This alarm is
reversible and the unit must not be restarted. When
water pressure is detected, the unit restarts to operate.
Install a jumper in case of no water pressure sensor in the
units with a water heater.
TU1, TU2
Break of common power line of the sensor or malfunction of the temperature sensor.
TU3, TU4
Break of common power line of the sensor or malfunction
of the temperature sensor.
TU5
Break of common power line of the sensor or malfunction of the temperature sensor.
TD5
Air temperature in the supply duct is below +5 °C. It is checked once in 17 minutes.
FE1
Actuation of differential pressure sensor in the supply air duct. The air filter in the supply duct must be replaced. This
alarm does not lead to shutdown of the ventilation unit, but acts as a warning sign.
FE2
Actuation of differential pressure sensor in the extract air duct. The air filter in the extract duct must be replaced. This
alarm does not lead to shutdown of the ventilation unit, but acts as a warning sign.
ERP
Communication disturbance with the control panel. Break of wire A or B. Breakdown of interface or control panel.
