EvoControl Ventilation - MPO1 Display

Under the menu Measurement values shown “Extra operating mode”, special operating modes as below.

AV:

• No special operating modes.

Defrosting:

• Defrosting of the heat exchanger takes place.

Heat retention:

• In the case of a water battery, a certain return temperature is maintained.

Freeze protection:

• In the case of a water coil, the actuator opens at a certain return temperature.

Refrigeration recovery:

• The rotor runs if the exhaust air temperature is cooler than the outside air.

Freezing:

• The unit blows in the cooler outside air when the indoor temperature gets too high.

Reserve operation (Emergency):

• The unit alarms but the extract air is running.

Moisture reduction:

• Increased ventilation and the heat exchanger recovers less moisture.

Winter drift:

• Changes the balance of ventilation and moisture reduction when the outside temperature goes below a certain temperature.

Deportation:

• The heat exchanger has stopped at sub-zero temperatures, the probable cause is ice formation, then an attempt is made to de-ice the heat exchanger before the alarm goes off.

VVX alarm control:

• The heat exchanger has stopped, then an attempt is made to start the heat exchanger before the alarm goes off.

Start-up:

• The unit is starting up the fans and the heat exchanger.

Presence:

• Attendance sensor/function activated.

See “Parameter settings” and other description points for more detailed explanation of functions and operating cases.
