Ecosense 4000 is universally compatible with any A/C that can be operated by remote controller. Ecosense 4000 is mains powered, taking its power supply directly from the A/C indoor unit. This model can be fitted directly adjacent to your A/C unit, therefore no wall channelling is required as the connecting cable passes directly through the side of Ecosense and into the A/C head unit. Ecosense uses Passive Infrared (PIR) technology to scan the room for occupancy. PIR is designed to detect the movement of heat and will not therefore be affected by items such as ceiling fans, curtains etc. When no movement has been detected it will send a signal to the A/C unit to switch it off. There is a red LED light that flashes to indicate the detection of movement. The 4000 can be programmed to set back the A/C to a more economic setting such as 26 deg, cool mode, low fan speed, if the A/C has been left running when the room has been vacated.

The 4000 is ideal for controlling air conditioning when being used in cool mode. If controlling your A/C in heat mode is important to you, we would recommend using the 4000+ with an auxiliary PIR sensor that can be positioned away from the A/C head unit. To maximise security, a unique button lock code can be input as part of the installation process.

After the occupant has left the room, Ecosense will continue to scan the room for a pre –set time – 15,30 or 45 mins before sending the signal to turn off the A/C.

Learn / Test
Once Ecosense has copied the infra red (IR) signal from the A/C remote controller, by pressing the ‘test’ button, you can test the unit to ensure the IR signal has been copied correctly.

Night setting
Should you not require Ecosense to control your A/C during the hours of darkness there are 2 night setting options.
Comfort Plus – allows the A/C to continue operating for two hours after darkness has been detected, after which time Ecosense 4000 will switch off the A/C.
Night Setting – Ecosense 4000 will go to sleep and not interfere with the operation of the A/C during the hours of darkness.

Clear memory
If at any time you wish to clear settings, there is a clear memory function to allow the unit to revert to factory default.

Tamper proof lockable key pad
In order to operate the function buttons, it is necessary to first enter a secure access code.
