14.4.2 Horizontal Airflow
(TZ20/25/35/42/50ZK RZ25/35/50ZK)
The horizontal airflow direction louver can be adjusted manually by hand.
(TZ60/71ZK)
Automatic horizontal airflow direction can be set using remote control; the vane swings left and right within the
angles as stated below. For heating mode operation, the angle of the vane depends on the indoor heat
exchanger temperature as Figure 1 below. It does not swing during fan motor stop.
Operation Mode Vane Angle (°)
Heating, with heat exchanger temperature
A 60 ~120
B 90
Cooling and soft dry 60 ~ 120
Manual horizontal airflow direction can be set using remote control; the angles of the vane are as stated below
and the positions of the vane are as Figure 2 above.

* The vertical vane angle tolerance is within +/- 5 degree.
14.5 Timer Control
There are 2 sets of ON and OFF timer available to turn the unit ON or OFF at different preset time.
If more than one timer had been set, the upcoming timer will be displayed and will activate in sequence.
14.5.1 ON Timer Control
ON timer 1 and ON timer 2 can be set using remote control, the unit with timer set will start operate earlier than
the setting time.
This is to provide a comfortable environment when reaching the set ON time.
60 minutes before the set time, indoor (at fan speed of Lo-) and outdoor fan motor start operate for 30 seconds to
determine the indoor intake air temperature and outdoor air temperature in order to judge the operation starting
time.
From the above judgment, the decided operation will start operate earlier than the set time as shown below.
