TABLE 2: HUMIDISTAT ACCESSORIES
H50 Internal humidity sensor for H270 humidistat and for H80 remote wall sensor.
H60 Duct humidity sensor to mount directly onto the back of any H270 humidistat.
H71 Duct humidity sensor to mount directly onto the supply or return of the ventilation duct.
H80 Wall humidity sensor to mount in any remote location.
S71 Outdoor temperature sensor to lower the setpoint in cold season.
H263 Programming tool for troubleshooting, viewing and modifying humidistat parameters.
008-0089 Replacement lexan (cover sticker) for H270 humidistat.
024-0048 Humidistat replacement base with connector (H50 internal humidity sensor not included).
H50 INTERNAL SENSOR H60 DUCT SENSOR H71 REMOTE DUCT SENSOR
This humidity sensor can be
mounted directly on 024-0048
humidistat base. This humidity sensor can be
mounted directly onto the back of
any H270 humidistat, with the
supplied hardware. This
transforms the humidistat into a
duct-mounted humidistat. This humidity sensor can be
mounted directly onto the supply
or return of the ventilation duct.
The H270 may be located on the
wall with humidity sensing from
the remote H71 sensor location.
H80 REMOTE WALL SENSOR S71 OUTDOOR
TEMPERATURE SENSOR
H263 PROGRAMMING TOOL
This humidity sensor can be wall
mounted in any remote location.
The humidistat may be located
on the duct or other location, with
humidity sensing from the H80
sensor location. This outdoor temperature sensor
is used to lower the humidity
setpoint to prevent condensation
on windows and structures. It is
usually installed in the fresh air
duct. This tool is used to change
humidistat parameters. It is also
useful for troubleshooting. Just
plug it in the humidistat through
the casing. See page 6 for more
details.
WARNING:
All H270 humidistats are intended to control equipment under normal operating conditions. Where failure or malfunction of H270
series humidistats could lead to an abnormal operating condition that could cause personal injury or damage to the equipment or
other property, other devices (limit or safety controls) or systems (alarm or supervisory) intended to warn of, or protect against,
failure or malfunction of H270 humidistats must be incorporated into and maintained as part of the control system.
