28.1.5 TEMPERATURE CONTROL SWITCH The temperature can be adjusted steplessly from low temperature to high temperature. The temperature level indicator lamps light up to display the temperature of the air coming from the vents. The more the blue lamps light up, the lower the temperature. The color of the indicator lamp changes while the switch is being pressed. When the temperature reaches the desired level, release the switch to set the temperature. The settings for each mode are retained in memory even when the starting switch is turned OFF. However, in the following cases, the settings must be made again.
When the machine has been out of use for more than seven days When the battery voltage is extremely low When there has been abnormal interference from outside When the fan switch is turned OFF (the setting is not kept in memory with only the air conditioner switch) Using the air conditioner at the FRESH position causes positive air pressure inside the cab, which will prevent the entry of dust from outside. The higher the position of the fan switch, the more effective the pressurizing becomes. 5-5 WA320-3MC
