1.4 Product character
1.4.1 Operating individually and operating simultaneously
The unit can realize individual operation which can control one unit running, stop, and adjusting running
mode. Also the unit can operate simultaneously which control multi indoor units at the same time.
1.4.2 Variable quantity of indoor unitIf you want to add or reduce the quantity of indoor units (of course
the match must correspond with the design), it can meet your need at any time. More convenient, more
random.
1.4.3 Universal outdoor unit, multiform indoor unit
We realize universal outdoor unit, and 6 kinds of indoor unit, choose freely according to customer’s favor
and indoor decoration, more stylish and more beautiful
1.4.4 The total capacity of indoor unit can be more than that of outdoor unit.
When all the indoor units are running at the same time, the actual capacity of every indoor unit is
proportional according to outdoor capacity.
1.4.5 Long distribution pipe and high drop
The distance of outdoor and indoor can be max. 40m, and the drop between indoor and outdoor can be
max. up to 25m, consequently, the installation can be more free, and can meet various need of the
customer.
1.4.6 Ceiling concealed type unit be equipped with high efficiency filter, and its high static pressure
can be up to 30Pa, running more silent, making room air more comfortable and more clean.
1.4.7 Auto-check function
The unit can display the malfunction codes on the control board by using advanced auto-check
technology ,convenient for user find and dwell with the abnormal running.
1.4.8 Auto –restart function (optional );
All indoor units have auto-restart function. When the power supply cut off suddenly, the unit will
automatically recover the previous running mode once the power supply is on.
1.4.9 Group control function
1.4.10 Weekly timer (optional)
1.4.11 Variable Control modes
Wired remote control ;
Remote control;
*Group control: a. With remote monitor function; b. Auto changeover function
