11.5 Dehumidification Function
Description
The FY/FA series controller provides dehumidification function to protect the heater. When the power is turned on, the heater is
dehumidified with low power. When the dehumidification is completed, the normal power is output to the heater.

Example
After the controller is turned on, when the PV does not reach 50°C, manipulated value fixed in 20%. When the time
exceeds 15 minutes or the PV is greater than 50°C, the controller will produce output of normal PID gain.
