4.6 MAIN WALL CONTROL USE
When the wall control is ON, press the MODE key to choose the operation mode of the ventilation unit.
Operating Mode label will then appear on LCD screen (AUTO, ECO, CONT and RECIRC).
AUTO MODE
The ventilation unit exchanges air intermittently on a one-hour cycle as follows: exchanges air during 20 minutes on low speed
and then recirculation on high speed for 40 minutes (or OFF for 40 minutes, see section 4.6.3). Repeat cycle after the 40-minute
period.
NOTE: The outdoor temperature value displayed during AUTO recirculation or AUTO off cycle period comes from the reading
while the unit is performing air exchange (first part of AUTO mode cycle). Also, keep in mind that outdoor temperature
reading is taken from the unit fresh air from outside port; due to the lenght of the insulated duct, the result of the reading is
slightly different from the real outside temperature.
