Perfect Humidity system is not available for single phase (-J volt-
age code) models.
The Perfect Humidity dehumidification system requires a field-
supplied and field-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 with isolated con-
tact set for dehumidification control. The humidistat is normal-
ly used in applications where a temperature control is already
provided.
Connecting a Field-Supplied Humidistat
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 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. 42.
Connecting a Field-Supplied Thermidistat device
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. 40) 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. 41). The dry con-
tacts must be wired between CTB terminal R and the PINK
lead to the LTLO switch with field-supplied wire nuts.
Refer to the installation instructions included with the field-
supplied Thermidistat device for more information.
