6 Ventilation mode change recommendation (RECOMMENDED, VENTILATION MODE) display
When PZ-60DR-E is used and the ventilation mode is set to Lossnay ventilation or bypass ventilation,
"RECOMMENDED" and "VENTILATION MODE" may be displayed alternately (for 10 minutes maximum).
This function informs the user of the suitable ventilation mode according to the automatic ventilation algo-
rithm. When a ventilation mode change recommendation has been displayed, more comfortable ventilation
can be provided by pressing the "Function selector" button of the remote controller and switching to another
ventilation mode.
( We r ecommend that "AUTO" be selected for the ventilation mode; however, there is no problem in leaving
the ventilation mode unchanged with "RECOMMENDED" "VENTILATION MODE" displayed.)
