Typical Unit Wiring Diagrams - Carrier WeatherMaker 48FC04-07 Installation Instructions Manual

Connecting 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. 35) to the 24v 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. 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. 38.

Connecting the Thermidistat device (33CS2PPRH-01)
1. Route the Thermidistat multi-conductor thermostat cable
(field-supplied) through the hole provided in the unit cor-
ner post.
2. Feed wires through the raceway built into the corner post
(see Fig. 35) 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. 39). Connect
D1 to the R terminal on the UCB. Connect D2 to the
HUM terminal on the UCB. Refer to the installation
instructions included with the Carrier Edge
midistat device for more information.
