5.20 Temperature Thermistor
• The temperature thermistor detects
temperature as a resistance value.
5.21 Float Switch
• A normally closed float switch is installed in the
drain pan to prevent the drain pan from
overflowing and alerts the user of an abnormal
condition. When condensation in the drain pan
becomes full, the float rises and turning the
switch OFF. After the float switch is OFF for 60
seconds, the unit turns off, error code "PU" and
buzzer turn on.
