The microprocessor based
RHCN-7000 Series on/off controller
provides control for humidifying or
de-humidifying. Relative humidity,
output status, and error messaging
can be viewed on the bright green
LED display. The controller features
user defined parameters including
setpoint, hysteresis, control type,
and probe adjustment. Access to
programming parameters can be
locked for security purposes using
the password protection feature.
Select RHCN-7000 models can
be interfaced with most RH
transmitters that provide a
0 to 1 Vdc or 4 to 20 mA output,
or an optional RH probe, model
RHCN-7000-RP can be ordered to
work with 0 to 3 Vdc input models.
