Complete Set of HVAC Debugging Tools - Central Air Conditioning/RV/Infrared Air Conditioning/Duct Debugging in One Stop

1, The complexity of HVAC debugging

HVAC system (HVAC) The system is one of the most complex subsystems in building automation. An air conditioning unit involves a compressor, Condenser, Evaporator, Expansion valve, Fan, Dozens of components including sensors, Collaborate through complex control algorithms.

When the air conditioning system malfunctions, Engineers need to read operational parameters, Analyze fault codes, Verify control logic. modbusDebugging Assistant "HVACThe toolbox provides 5 specialized tools.

Two, Air conditioning debugging assistant — Full brand protocol debugging

This is the most essential part of the toolboxHVACDebugging tools, supportMultiple air conditioning brands and communication protocols.

2.1 Multi brand/multi protocol support

2.2 Functional modules

The tool includes 8 functional tabs:

• control panel: Power on/off, pattern (Refrigeration/Heating/Air Supply/Dehumidification) , Set temperature, Wind speed (Low/Medium/High/Automatic) , Wind direction (Swing the wind up and down/left and right)
• Status monitoring: Indoor temperature, Outdoor temperature, Compressor frequency, Electronic expansion valve opening degree, Fan speed, Operating current, Exhaust temperature, Return air temperature, Condensation temperature, Evaporation temperature
• Timed/Sleep: scheduled power on (Accurate to the minute) , Sleep curve (Gradually increase/decrease temperature) , Energy saving mode switching
• Device discovery: Scan indoor air conditioning units in the network, Display the address and status of each machine
• Protocol debugging: Original message sending/receiving window, Used for analyzing and testing air conditioning communication protocols
• Batch control: Simultaneously perform the same operation on multiple air conditioners (If the entire building is uniformly heated26°C)
• Energy consumption analysis: Record the operating time and power consumption of each air conditioner, Generate daily/weekly/monthly energy consumption reports
• journal: Complete operation logs and fault logs, Support export

Three, Infrared air conditioning debugging tool

in the light ofInfrared remote control air conditionerDebugging tools. Using a mobile phone infrared transmitter (Or external infrared module) Send the air conditioning remote control code:

• Infrared code library: Built in infrared code library for mainstream brand air conditioners (Gree/Midea/Haier/AUX/Daikin/Mitsubishi, etc) , Remote control without the need for learning
• Code library learning: Press the original remote control towards the infrared receiver of the phone, Automatically parse and store infrared codes
• Code library sharing: Export and share the learned infrared codes with others for use
• Automated control: Combined with temperature sensors, Realize automatic temperature control (higher than28°CTurn on refrigeration, lower than18°COpen heating)

Four, Central air conditioning gateway debugging tool

Central air conditioning gateway (Like DaikinDTA116A61Wait) It is a key equipment that connects the air conditioning system and building automation system. Gateway debugging tools provided:

• Gateway connection status: Check the communication status between the gateway and the air conditioning system
• List of indoor units: Obtain the addresses and status of all online indoor units through the gateway
• Centralized control: Centralize control of all indoor units through the gateway (Set the upper and lower limits of temperature, Compulsory operation mode, etc)
• Fault reading: Read the air conditioning system fault codes stored in the gateway and parse them into Chinese descriptions
• Schedule management: Configure a scheduled power on/off schedule in the gateway, Gateway local execution

Five, Duct fan and air conditioning debugging tool

Wind pipe machine (Ductless Mini-Split) It is the most common type of air conditioner for household/commercial use. Debugging tool functionality: Indoor temperature/set temperature/operating mode/wind speed control/timed switch/fault code reading and analysis.

Six, Central air conditioning system debugging (Smart home)

Central air conditioning debugging tool in smart home scenarios: Support passedModbus RTU/TCPConnect the air conditioning gateway (Building control brands such as Hailin/Honeywell/Siemens) , Realize comprehensive monitoring and debugging of the central air conditioning system.

Seven, Summary

5FundsHVACThe debugging tool covers the full range of debugging needs from small split air conditioners to large central air conditioning systems. Whether it's on-site maintenance or building management system integration, All parameters diagnosis and control of the air conditioning system can be completed on the mobile phone.
