3. Easy operation line controller
• Cooling/Heating/Fan/Auto
• Error indication
• Timing on/off
Units are completely factory-wired with necessary controls and wiring terminals for power wiring. Microprocessor controls the cooling,heating and ventilating modes in response to signals from sensors measuring indoor and outdoor temperature. It will keep accurate temperature control, minimum drift from the set point and provide better building comfort.

4. Easy installation and maintenance
