Displaying the Relative Humidity
The 072000 normal display shows the humidity
level in the home. The example at right shows
the humidity reading at 36%. The "RH" symbol
blinks when the humidistat is requesting (calling
for) humidification. The "RH" symbol remains
steady when the humidity set point is satisfied.
NOTE: Allow 24 hours for the 072000 to fully
stabilize and display the accurate humidity
level in your home.
Changing the RH Setpoint
When the up or down %RH keys are pressed
once, the 072000 displays the relative humidity
set point. Holding the UP key will raise the RH
set point and, holding the DOWN key will lower
the RH set point.
Upon initial power up, the 072000 defaults to
an RH set point of 30% RH. You can adjust the
set point as desired no matter which mode of
operation you prefer. See "Selecting Manual
Operation" and "Selecting Automatic
Operation" for more information on the proper
setting of the RH set point.
Displaying the Outdoor Temperature
Pressing the OD TEMP key will display the
outdoor temperature. The 072000 will display
outdoor air temperatures from -9 to 98°F.
Selecting Manual or Auto Operation
Moving the AUTO/MAN switch to the MAN
position selects manual operation. The 072000
will maintain the RH set point selected with the
up and down %RH keys. As the outdoor
temperature changes, the home-owner will
have to re-adjust the RH set point to achieve a
c o m f o r t a b l e e n v i r o n m e n t a n d a v o i d
