Fig. 31 — Low-Voltage Connections
Unit Without Thru-Base Connection Kit — Pass the ther-
mostat control wires through the hole provided in the corner
post; then feed the wires through the raceway built into the
corner post to the control box. Pull the wires over to the ter-
minal strip on the upper-left corner of the Controls Connec-
tion Board. See Fig. 32.
NOTE: If thru-the-bottom connections accessory is used,
refer to the accessory installation instructions for informa-
tion on routing power and control wiring.

Heat Anticipator Settings — Set heat anticipator settings at
0.14 amp for the first stage and 0.14 amp for second-stage heat-
ing, when available.
HUMIDI-MIZER ® CONTROL CONNECTIONS
Humidi-MiZer – Space RH Controller
NOTE: The Humidi-MiZer is a factory installed option
which is available for 07 models only.
The Humidi-MiZer dehumidification system requires a
field-supplied and installed space relative humidity control de-
vice. This device may be a separate humidistat control (contact
closes on rise in space RH above control setpoint) or a combi-
nation thermostat-humidistat control device such as Carrier’s
EDGE ® Pro Thermidistat with isolated contact set for dehu-
midification control. The humidistat is normally used in appli-
cations where a temperature control is already provided (units
with PremierLink™ control).
To Connect the Carrier Humidistat (HL38MG029) (See
Fig. 33)
1. Route the humidistat 2-conductor cable (field-sup-
plied) through the hole provided in the unit corner
post.
2. Feed wires through the raceway built into the corner post
(see Fig. 32) to the 24-v barrier located on the left side of
the control box. The raceway provides the UL-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. 34.
To connect the Thermidistat device (33CS2PPRH-01) (See
Fig. 35)
1. Route the Thermidistat multi-conductor thermostat
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. 32) to the 24-v barrier located on the left side of
the control 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. 36). The dry
contacts must be wired between CTB terminal R and the
PINK lead to the LTLO switch with field-supplied wire
nuts. Refer to PremierLink Installation, Start-up, and
Configuration Instructions for more information.
