The compressor needs a 3 minutes delay to restart after each stop. The compressor is designed to immediately start when the air conditioner is switched on for the first time. Error codes will flash according to a 2Hz frequency. Ambient temperature probe faults and evaporator temperature probe faults are checked and displayed when the air conditioner is on standby. When a fault is detected affecting the air conditioner, the display unit shows the corresponding error codes instead of temperature indications.

The faults are described and displayed in the following table: Fault Displayed error code Ambient temperature sensor fault.e1 Evaporator temperature sensor fault.e2 No Coolant Gas or E4 Evaporator Probe not in its housing or.e4 External Fan fault.e4 Remarks: 1. 4ĥ Fault and Auto-diagnostic Display This control device detects any type of fault by sampling and checking the faults are shown on a display unit. (2) Evaporator temperature sensor: Casing: Φ 5 mm copper or steel pipe with length 25 mm, R(25)=5K, B=3274☑% Cable length 500 mm, white cable. Sensor (PROBE) models and characteristics (1) Ambient temperature sensor: Casing: resin, R(25)=5K, B=3274☑% Cable length 500 mm, black cable. Note: The code Tr mentioned in the technical features refers to the vehicle internal temperature, while Tp refers to the Evaporator probe temperature and Ts refers to the pre-set temperature.
Emergency push-button If you have lost your remote control or are otherwise unable to use it, the air conditioner may be started by pressing the emergency button. (3) 2 DIGIT display unit: Displays the ambient temperature and error codes (in the event of air conditioner failure). (2) Operating mode TWO-COLOUR LED: Red Light On: Heating and Green Light On: Cooling. (1) Power-on RED LED: This light goes on when power is connected.
A 2 digit lighted display, Power-on LED, Two-colour LED for the cooling/heating operating modes. The display board (on the diffuser) includes: 1. The electronic control board controls the following elements: Compressor, four-way valve, external fan, internal fan, control probe. Emergency and Auto-diagnostic button 3Ĥ ELECTRONIC CONTROL BOARD: CONNECTIONS Control unit components (Ⅰ)This control unit mainly consists of: a control panel, display and receiving board, infrared remote control etc. LED operation indicators: RED for HEATING, GREEN for COOLING. Ambient temperature and error codes (in the event of air conditioner failure) are shown on the 2-digit display. Protection against faults caused by failure to cool or failure to heat. Directional (cold/hot) control valve with 3 minutes delay. Anti-freeze protection (conditioning): automatic by evaporator temperature measurement with probe minute delay before compressor restart as a compressor protective measure.
High temperature protection (heat pump): automatic by evaporator temperature measurement with probe. Defrosting: automatic defrosting of the condensing unit with probe. When the speed is set to automatic, the corresponding remote control display is as follows: ventilation speed indicator increasing from left to right (rotating) with a 0.5 second interval. Ventilation speeds: Automatic, high, medium and low. Operating modes: Automatic, cooling and heating 2. Internal fan: Three-speed motor REMOTE-CONTROLLED FUNCTIONS 1. External fan: one speed, 5A/240VAC relay. 12 2ģ GENERAL FEATURES Air conditioner power components: 1. 4 Sensor (PROBE) models and characteristics pag.
