1).WP can be used as detecting end of blower switch or water detection switch. If WP and ground are not connected by empty
node like picture 1, but connected through optocoupler, the connection will be like picture 2.
1)WP input terminal can use water switch or fan switch's test terminal, Please pay attention that WP is through optocoupler
connected with ground (G) as (figure2) , not as (figure 1). 2)(PWM control): Requirements of the PWM frequency f≥20kHz,
amplitude(peak value)≤5V
