WORKING :
In normal working conditions when power is turned ON. Display will show Cycle Time, Room temperature. Now depending on the Room temperature & Room temp. set points of A/C1,A/C2, they will be turned ON after their respective power on delay & this condition system makes ON/OFF of A/Cs depending on the set point of Temperature & Cycle time in tens of minutes. If room temperature exceeds the set point of HIGH TEMP, ALARM RELAY contacts get closed.
To view/change set points of A/C1 Cut In, A/C2 Cut In, High temperature & Change over cycle time in tens of minutes press SET key.
PARAMETER SET POINTS :
- Cycle Time
- AC 1 ON set point
- AC 2 ON set point
- Hysteresis
- Room High
- Hysteresis
- Room Low
- Hysteresis
- Under Voltage
- Over Voltage
- 1. To change set points, press SET key once. Display will show PASSWORD Now enter correct password (15) by using INC/DEC keys & then press ENTER key. On display we can see existing Cycle time You can change it by using INC or DEC keys. Now by pressing Enter key you can go to next parameter i.e. AC 1 ON set point, You can change set point by Inc / Dec key. After changing set point again press Enter key to go to next parameter. This way we can Set AC 1/ AC2 ON Set points, Hysteresis, Room High/Room Low set points, Under Voltage, Over Voltage set points. At last again press Enter key. All parameters are now set as per requirement. Unit will go to RUN Mode Automatically.
Cell sites vitally need air conditioning systems. The heart of an Air conditioner is its compressor. To control A/Cs ‘Aircon Controls’ has developed a new innovative product
” 2 A/C CONTROLLER ” (with Temperature Control)
2 A/C Controller is a Microprocessor based system, which controls operation of two A/Cs. System also provides facility to indicate High temperature Alarm. All the set points such as Compressor Cut In Temp., High Temp & Cycle Time are site selectable & user can easily set them by using keys provided on the front panel.
