6 Ventilation mode change recommendation (RECOMMENDED, VENTILATION MODE) display
When using PZ-60DR-E and the ventilation mode is set to Lossnay ventilation or bypass ventilation, "REC-
OMMENDED" 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 algorithm.
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 ventila-
tion mode.
(We recommend that "AUTO" be selected for the ventilation mode; however, there is no problem in leaving
the ventilation mode unchanged with "RECOMMENDED" "VENTILATION MODE" displayed.)
