Model Fresh S125 HT
Plug fan like the previous model T, but with both
after-run timer and humidity control. The timer function
is either 0 or 15 minutes. This is controlled
using the jumper on the circuit board. The humidity control
is adjustable between 50 an d90% RH. It is adjusted using the
potentiometer under the front cover. The fan starts when
the humidity level exceeds the set value and stops when
the level has fallen below this value.
