HVAC Control Modules generally operate at 5 volts. The brain of module is CPU and EPROM is used for program storage calibration. It allows software to be flash upgraded. The modules can be damaged or mis-set if ignition is on and battery is reconnected. A braided wire is used to ground module for suppressing RFI than regular wire.
The HVAC control panel allows the user to set desired temperatures and to select different operating modes. The control panel also contains the master control MCU that is networked with the evaporator fan motor control and outside compressor unit.

HVAC Equipment Liner provides thermal and acoustical control in air conditioning, heating equipment and appliances. It can be used in a variety of applications including air conditioners, furnaces, VAV boxes, roof curb applications and in HVAC equipments. It is composed of borosilicate glass fibers that are incombustible and non-hygroscopic.
HVAC Inspection Service is used to determine the need for cleaning air conveyance systems. It is also used to perform a visual inspection of the system components. This is a method of determining the need for cleaning, and for identifying any excessive wear on mechanical equipment. This inspection report is an important step in preventive maintenance program. The report can show facility occupants that the air conveyance systems are being monitored and are free of visible contaminants.
