HUMIDI-MIZER CONTROL CONNECTIONS
®
Humidi-MiZer Space RH Controller
NOTE: The Humidi-MiZer system is a factory-installed option.
Humidi-MiZer system is not available for single phase (-3 volt-
age code) models.
The Humidi-MiZer dehumidification system requires a
field-supplied and field-installed space relative humidity con-
trol device. This device may be a separate humidistat control
(contact closes on rise in space RH above control setpoint) or
a combination thermostat-humidistat control device such as
Carrier's Edge ® Pro Thermidistat™ device with isolated con-
tact set for dehumidification control. See Fig. 36 and Fig. 37.
The humidistat is normally used in applications where a tem-
perature control is already provided (units with SystemVu™
control).
