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 air temperature coming from the vents. The more blue lamps that are lit, the colder the temperature is. 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, the settings must be made again in the following cases: When the machine has been out of use for more than 7 days.
When the battery voltage is extremely low. When there has been abnormal interference from the outside. When the fan switch is turned OFF (the setting is not kept in memory with only the air conditioner switch) If the air conditioner is used in the FRESH position, the inside of the cab will be pressurized and this will prevent the entry of dust. The higher the position of the fan switch, the more effective the pressurizing becomes. WA450-3MC 5-5
