Room Card Function
Room Card Function
1) Room card function (SW1-4) switched off
If room card function switched off, indoor unit could be switched on/off by remote controller, wired controller, central
controller and dry contact (When dry contact close the unit switched ON, when dry contact disconnect the unit
switched OFF).
When the dry contact close, the unit will operate as per the state set by controller during the previous operation
(EE memory separated), that will remember operating modes, fan speed, temperature setting, healthy mode, swing
position etc. Timer and sleep mode will be canceled when the unit startup again.
When dry contact disconnect, indoor unit can be controlled by controller when turned off.
2) Room card function (SW1-4) switched on
If room card function valid, the indoor unit will only runs when the room card connect first then switched ON by
remote controller, wired controller or central controller. (The indoor unit stops when the room card disconnects, or
switched OFF by remote controller, wired controller or central controller.)
When dry contact close, the indoor unit will be at stand-by state, indoor unit will be ON and run as per the controller
setting state when it’s switched on by wireless controller or auto start.
When dry contact disconnect, the indoor unit will switched on immediately and cannot be controlled by controller.

Setting Method of Temperature Compensation Tcomp
A. Wired control type unit: this function is not available
B. Remote control type unit:
In cooling or heating mode, there is always with the temp. compensation.
In heating mode: In 24
o
C heating mode, press SLEEP(or SWING) button 7 times continuously within 5 seconds,
indoor buzzer sounds twice, that shows temp. compensation works. Switch on the unit in
heating mode by the remote controller, press TEMP button to set the set temp., so temperature compensation=the
current set temp. - 24
o
C. For example, if the set temp. is 24
o
C, the temp. compensation is 0
o
C; if the set temp. is
25
o
C, the temp. compensation is 1
o
C. The max. compensation temp. is 6
o
C (the set temp. is 30
o
C). If you want to
cancel it, set the temp. as 24
o
C.
