Models PADP50 and PADP70 are the only units that run a continuous fan. The reason for this is to circulate the air in the space and improve the humidity reading. By doing so the compressor won’t run as often.
All of the other models have a fan that cycles with the compressor. Unless the units are running on “Continuous” mode, the unit will run according to the set humidity level. The compressor will cycle off first, three minutes (3 min) after the compressor the fan will cycle off.
