Heat Anticipator Settings — Set heat anticipator settings at 0.14
amp for the first stage and 0.14 amp for second-stage heating.
Transformer Connection for 208-v Power Supply — All units
except 208/230-v units are factory wired for the voltage shown
on the nameplate. If the 208/230-v unit is to be connected to a
208-v power supply, the control transformer must be rewired by
moving the black wire with the

terminal on the primary side of the transformer. Refer to unit la-
bel diagram for additional information.
PERFECT HUMIDITY™ CONTROL CONNECTIONS
Perfect Humidity – Space RH Controller
NOTE: The Perfect Humidity system is a factory installed op-
tion which is available for size 17, 20, 24 and 28 units
equipped with RTPF condenser coils.
The Perfect Humidity 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) (see Fig. 33) or
a combination thermostat-humidistat control device with isolated
contact set for dehumidification control. The humidistat is nor-
mally used in applications where a temperature control is already
provided (such as a third-party Building Management System).
To connect 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. 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. 33. Refer
to the instructions for the field-supplied humidistat for more
information.

CAUTION
CAUTION
Failure to follow this caution may cause a short circuit.
Carefully check the connection of control conductor for
indoor fan control at terminal G. Connecting the indoor
fan lead to terminal C will cause a short circuit condition
which can cause component damage inside the unit or at
the thermostat.
