Chapter 1 - Features
Schedule Setting
16 periods can be set.
ECO-IR built in weekly schedule.
Temperature control
When the ambient temperature is below the set value, ECO-IR will set air
conditioning on fan mode.
Cycle Suspend
Multiple air conditioners take turns running in fan mode (Compressor turns off)
to achieve energy-saving. According to the actual test results, effective energy
saving rates up to 16.7%.
Infrared copy and control
ECO-IR can copy infrared code and control A/C.
Users don't need to modify A/C.
Digital output (DO)
ECO-IR which has built-in 2 set of DO relays, can stop supply power to device.
The application of ECO-IR is installed in central air conditioning system,
conventional device, etc.

becomes one of condition.
For example, time control and PIR are the condition. If two conditions were
achieved: PIR detects people passed and this period is turned on in period
setting, A/C power will turn on.
Another example is time control and temp. control power.

11
3-3 Cycle Suspend
Let you save more energy by cycle suspend. This function can force to turn fan in a
short time.
Step 1. Set cycle suspend. It means “how long is a cycle? “ The shortest cycle is 2
minutes.
Step 2. Set fan time in a cycle.
Step 3. Set start time and end time, then cycle suspend will work in this period.

Delay Fan Time: To avoid multiple air conditioners turn fan in the same time, user
can set delay fan time to delay A/C turning fan.
12
3-4 Mode Setting
DI Mode：(1) OFF：DI deactivated
(2) Button: ECOIR DI can connect external button which manually control
A/C power on/off or cool/fan.
(3) Motion：According to people motion, PIR controls A/C.
DI Reference: Advanced application. If DI mode turn motion and DI reference turn on,
PIR control becomes one of condition. PIR and temp. control power are the condition.
DO Mode：(1) IR + Relay: Infrared and relay are controlled together.
(2) IR Only: Only infrared is controlled.
(3) Relay Only: Only relay is controlled.
(4) IR + Relay0：Infrared and relay0 (control power) are controlled
together. Relay1 (control fan / cool)
Control Delay Time: Set ECO-IR to delay working by 0~10 second.
DI Mode: Motion- Delay close power
Idle time: Last cool mode time. If PIR didn’t detect people motion, idle time can
delay turning fan mode.
Fan time: Last fan mode time. If PIR didn’t detect people motion, fan time can delay
turning fan mode.
Fan & Cool based on power: Default: ON. This function is avoiding abnormal
operation because some of air conditioners cool/fan infrared code have power
infrared code.
13
