Description

What is HOWO A7 Control panel WG1664820003?

HOWO A7 Control panel WG1664820003 is an air conditioning control panel, mainly used to control the on-board air conditioning.

The design of the air conditioning control panel for HOWO A7 usually focuses on practicality and durability, while also taking into account the convenience for the driver to operate. Here is a detailed introduction to the functions and features of HOWO A7’s air conditioning Control panel WG1664820003.

Air conditioning control panel WG1664820003 layout and common components:

The heavy-duty truck air conditioning control panel is usually located near the central console or dashboard of the cab, and it includes the following core components:

Mode selection knob/key

• Windshield defrost (MAX Defrost): Quickly remove fog on the front windshield.
• Face outlet: Directly blow air towards the driver’s upper body.
• Foot outlet: Downward airflow, suitable for heating in winter.
• Mixed mode (Face + Foot): Balances air supply to the face and feet.
• Wind speed adjustment knob: Multiple gears (usually 1-4 or 1-6) to adjust the air volume.
• Temperature control knob: Cold and hot zones (blue for cooling, red for heating), some models have automatic constant temperature (marked as “AUTO”).
• AC switch: Compressor start/stop button, press it when cooling (some models are linked with the temperature knob).
• Internal and external circulation switch:
• Internal circulation: Blocks external odors/dust and quickly cools down.
• External circulation: Introduces fresh air to prevent window fogging.
• Auxiliary function buttons: Rear window defogging and independent temperature zone control

Special design considerations for the air conditioning control panel WG1664820003:

1. Large buttons/knobs: Easy to operate with gloves, suitable for truck driving environments.
2. Backlight display: Clear to see at night, usually in orange or green LEDs.
3. Dustproof and waterproof: The panel has good sealing performance, suitable for harsh environments such as construction sites and mining areas.
