The display may be RH, Temperature or Dewpoint readings
depending on your Reading Configuration selections. Factory
defaults are shown. Note

: a

Dual Display unit allows the user
to observe the Relative Humidity or Dewpoint (upper display)
and Temperature Value (lower display), at the same time.

Disassembly Instruction:

If necessary, the unit may be removed from the panel and
opened.

Warning: Disconnect all ac power from the unit
before proceeding.

1. Make sure the AC power is disconnected.
