ELECTRONIC HUMIDISTAT: H200
•
ONE OR TWO STAGES
DESCRIPTION
The H200 series low voltage, microcomputer-based PI
(proportional and integral) humidistats are designed for
accurate humidification and/or dehumidification control
in non-corrosive commercial applications such as:
hospitals, schools, office buildings, retail stores,
museums, computer rooms, etc.
The H200 series is available with one or two outputs
for maximum flexibility. Outputs can be of the following
type: proportional, on/off, and pulse width modulation
(PWM). In addition, a wide variety of mounting
configurations is available. Sensing options include
remote duct and room as well as integral room and
duct.
Setpoint adjustment can be either concealed or
exposed, adding even more versatility to the product.
Exposed models feature internally selectable minimum
and maximum setpoint knob stops.
In order to facilitate periodic recalibration, the H200
series contains a unique autocal key, which permits
instant recalibration (see dimension drawing on page 5
for location).
Each humidistat is computer calibrated and factory
programmed with default parameters. All control
parameters (such as proportional band, stage
differential, etc.) may be changed in the field with the
H263 programming tool without having to remove the
thermostat cover. The H263 also doubles as a
diagnostic tool and indicates the status of all the inputs
and outputs, and will reduce troubleshooting time by
quickly identifying the specific problem.
