: It is suggested to ensure the Auto--Changeover
function of an installed thermostat is enabled when used
in conjunction with the Humidi--MiZer Adaptive
Dehumidification system.
Humidi--MiZer System – Space RH Controller —
The Humidi--MiZer dehumidification system requires a
field--supplied and installed space relative humidity control
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 with
isolated contact set for dehumidification control.
NOTE
: Use of a humidistat device is not permitted on
48LC units equipped with RTU Open control; these units
require
use
of
a
field--supplied
RH
sensor
(33ZCSENSRH--02 or 33ZHCSENDRH--02), or a ZS series
sensor with humidity sensing. SystemVu
t
controls requires
a Space Humidistat (HL38MG029) or a Wall Mount Space
Humidity Sensor (33ZCSENSRH--01) or a Duct Mount
Humidity Sensor (33ZCSENDRH--01).
To connect the Carrier humidistat (HL38MG029):
1. Route the humidistat 2--conductor cable (field--supplied)
through the hole provided in the unit corner post.
2. Feed wires through the raceway built into the corner
post (see Fig. 40) to the 24--v barrier located on the
left side of the control box. The raceway provides the
ETL--required clearance between high--voltage and
low--voltage wiring.
3. Use wire nuts to connect humidistat cable to two PINK
leads in the low–voltage wiring as shown in Fig. 42.
