Leveraging on our industrial experience, we have also been able to manufacture a wide range of Dual AC Controllers that are capable of controlling two Air Conditioners at a time. These are provided with separate Phase supply for both the ACs and control by pass features too.
- Supply Voltage : 230 V AC, 50 Hz +/- 15% separate for each A/C.
- Contact rating : 30 A at 230 V AC for compressor Live Outputs & 5 A at 250 V AC Alarm Potential free outputs(C, N/O)
- Temperature Sensor : Thermistor sensor NTC 10K @ 25 °C metal body with clamp. Sensor cable length 2.75 meters.
- Temperature sensing range : 0.0 to 55.0 degree C.
- Resolutions : 1 V for voltage, 0.1 A for Current & 0.1 degree C for Temperature.
- Auto/Controller Bypass Switch is used to bypass the controller i.e. A/C 1 & A/C 2 will remains ON(irrespective of temperature demands) if both switches are in ON condition.
- Indications :
a) Supply ON for A/C 1 & A/C 2: Colour: Yellow
b) Auto Mode for A/C 1 & A/C 2: Colour: Green
c) Manual Mode for A/C 1 & A/C 2: Colour: Red
d) A/C 1 & A/C 2 ON: Colour: Green
e) A/C 1 & A/C 2 Fault: Colour: Red
f) Room High: Colour: Red
g) Healthy: Colour: Green
- Keys : four keys for parameter settings.

- UP Arrow Key : To increment the set point/To view next menu/To view next set point in the menu.
- Down Arrow Key : To decrement the set point/To view previous menu/To view previous set point in the menu.
- Enter Key : To come out of SE mode/To enter into menu/ To accept the password.
