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. The control panel is extremely easy to program and gives quicker commissioning and set-up as well as rapid fault diagnosis.

HVAC control system is a computerized control system for climate control in buildings. It may have microprocessors. These systems typically use one or more central controllers to command and monitor the remote terminal unit controllers. They communicate with one or more personal computers that are used as the operator interface. These control systems are typically used on large commercial and industrial buildings to allow central control of many HVAC units around the building.

HVAC cooling towers are used for large water source or industrial HVAC cooling systems. HVAC cooling towers utilize a non-glued design, completely avoiding VOCs.

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.
