VENTO Ergo A50/50-1 Pro
The jumper between the contacts 1 and 2 or 2 and 3 of CN7 socket
connector determines the air flow direction in Ventilation mode:
• If the jumper connects the contacts 1 and 2, air is extracted from the
room in Ventilation mode (factory setting).
• If the jumper connects the contacts 2 and 3, air is supplied to the room
in Ventilation mode.
The jumper position at each connected in series unit determines a
rotation direction in the Ventilation mode and an operating phase in the Heat
Recovery mode. I.e. if the jumper at the first unit connects the contacts 2 and
3 and the jumper at the second unit connects the contacts 1 and 2, the units
operate in opposite directions in the Heat Recovery mode.
