Small Reminder For The Shopkeeper: Generally, There Are 5K–10K For Hanging Up.Cabinet Use 10K—20K More.Specific Need To Measure The Resistance Value With A Multimeter By Yourself

General Ambient Temperature Thermostat, Is A Small Thing That The Outdoor Unit Against The Wall Side Black Near The Fin.The Tube Temperature-Sensitive Temperature Head Is Inserted On The Wall Of The Coil Inside The Outdoor Unit.

The Copper Head Is To Detect The Copper Tube, And The Temperature Conducts Quickly; The Plastic Head Is Generally Used To Detect Ambient Temperature, Corrosion Resistance And High Reliability

How To Judge The Resistance Value Of The Air Conditioner Temperature Sensor

Air Conditioning Circuit Designers Are Based On Room Temperature 25 Degrees, That Is, When 25%, RTl = R1, RT2 = R2, A And B Point Voltage Is 2.5V.Some Circuits Are Equipped With R3, R4, Which Mainly Plays A Buffering Role.When The Ambient Temperature Rises, The RTI Resistance Value Is Reduced, The A-Spot Voltage Rises, And The Comparator Outputs A Differential Pressure, And After A Series Of Processing Inside The CPU, It Is To Control The Operation Status Of The Internal And External Machines.

Large Air Conditioner, Inverter Air Conditioner Exterior Control Board, Temperature Sensor Connected To Vi’s Sampling Voltage Is Not 2.5V, But 1/4 Power Supply Voltage, That Is, 1.25V, In Fact, There Is A Way To Determine The Resistance Value Of The Thermal Resistance Is Particularly Simple, Choose A 50k Potentiometer And A Universal Plug Of The Thermal Resistance, In Order To Facilitate, You Can Use A Long Wire To Connect It Between, Unplug The Suspect Thermal Resistance, Plug In The Universal Plug, GiveThe Air Conditioner Is Powered On, Test The Voltage Of The Potentiometer 5v To Test The Two Terminals Of The Potentiometer, Slowly Turning The Potentiometer Handle, When The Voltage Is 2.5V, Stop Turning, The Resistance Value Of The Potentiometer At This Time Is The Resistance Value Of The Thermal Resistance.For Example: The Resistance Value Is 8k And The Ambient Temperature Is 30?Left And Right, Then This Temperature Sensor Has A Resistance Of 10k.

How To Judge The Quality Of The Air Conditioner Temperature Sensor

If The Air Conditioning Temperature Sensor Is Broken, The Following Phenomena Will Appear, Which Can Judge The Quality Of The Air Conditioning Temperature Sensor:

1. The Indoor Ring Temperature Sensor Has Increased The Resistance Value, Causing The Air Conditioner To Start Frequently.

2. The Resistance Value Of The Indoor Tube Temperature Sensor B
