Ceto UMR-903 Operation Manual

CETO UMR‐903 is a Universal Motion Remote with a motion
sensor, programmable for unparalleled energy savings up to
60% in the operation of any air‐conditioning system that
incorporates a built‐in remote‐control receiver. CETO can
detect human motion within a 25‐foot distance and control
the operation of an air‐conditioner according to the presence
of human motion and can be programmed to turn the air‐
conditioner completely off or have the setting temperature
increased to a desired setting for incredible energy savings.
It is capable of operating over 6,000 different brands and
models of air‐conditioners.
BRAND CODE Setting

codes for one brand, try the first. If it doesn't work, please try
the second until it does work. For example: MITSUBISHI, first
you try '0476', if it doesn't work, try '0477'.

(the code displayed on the LCD screen increases automatically).
When the air‐conditioner receives the corresponding signal and
produces a buzzer sound, press any button to confirm the setting
quickly.
 After turning on the air conditioner, try other function buttons. If
they don't work, repeat above steps until they do.
PIR Human Detection Setting
The 'PIR' button is used for 'ECO' and 'DELAYED STOP' functions.
ECO function is the default setting for COOLING, HEATING and DRY
modes. The 'DELAYED STOP' function is disabled when CETO is in
ECO mode.
Every time the air conditioner is turned on or switched between
different modes, the ECO function sign will be displayed. In ECO
Mode, the air‐conditioner will automatically adjust temperature
settings once there is no motion detected within the given time.
In 'DELAYED STOP' mode, the unit will stop running after the set
time and will not turn back on automatically when motion is
detected.
