HUMIDISTAT
The humidistat is designed to mount on the return air plenum of
your furnace or on an interior wall of the home. The return air
plenum, however, is the preferred location for sensing the aver­
age humidity throughout your home and is the location covered
by installation steps 1 through 11. (If you decide on the wall mount
location, the humidistat control unit must be removed and mounted
to the opposite side of the plastic backplate so it will be housed
inside of the plastic cover - omtt shaft e:denslon - purchase addi­
tional low voltage wire and run wire inside of wall to exit hole
within the lower opening of the backplate.)
NOTE: The humidistat as supplied is assembled for return
air plenum installation (Fig. 16.).
