HUMIDI-MIZER — SPACE RH CONTROLLER
NOTE: The Humidi-MiZer
®
system is a factory-installed option.
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, see Fig. 54) or a combination
thermostat-humidistat control device such as Carrier’s Edge
®
Pro
Thermidistat™ device with isolated contact set for dehumidifica-
tion control (see Fig. 55). The humidistat is normally used in ap-
plications where a temperature control is already provided (units
with SystemVu™ control).

To connect the Carrier humidistat (HL38MG029):
1. Route the humidistat 2-conductor cable (field-supplied)
through hole provided in the unit corner post.
2. Feed wires through the raceway built into the corner post (see
Fig. 53) to the 24 v barrier located on the left side of the con-
trol box. The raceway provides the UL-required clearance
between high-voltage and low-voltage wiring.
3. Connect one of the leads from the 2-conductor cable to the
HUM terminal on the UCB (Unit Control Board). Connect
the other lead to the R terminal on the UCB. See Fig. 56.
To connect the Thermidistat device (33CS2PPRH-01):
1. Route the Thermidistat multi-conductor thermostat cable
(field-supplied) through hole provided in the unit corner post.
2. Feed wires through the raceway built into the corner post (see
Fig. 53) to the 24 v barrier located on the left side of the con-
trol box. The raceway provides the UL-required clearance
between high-voltage and low-voltage wiring.
3. The Thermidistat has dry contacts at terminals D1 and D2
for dehumidification operation (see Fig. 57). Connect D1 to
the R terminal on the UCB. Connect D2 to the HUM termi-
nal on the UCB. Refer to the installation instructions
included with the Carrier Edge
