Perfect Humidityt Control Connections

Perfect Humidity - - Space RH Controller —
NOTE: Perfect Humidity is a factory installed option
which is only available for units equipped with RTPF
condenser coils.
The Perfect Humidity 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) or a combination thermostat- - humidistat control
device such as Bryant's EDGE
isolated contact set for dehumidification control. The
humidistat is normally 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 bushing in the unit's louvered end panel
(see Fig. 42).
2. Route the cable through the snap- - in wire tie and up to
the web bushing near the control box.
3. Feed the cable through the bushing and into the bottom
left side of the control box after removing one of the
two knockouts in the corner of the box. Use a connector
to protect the cable as it enters the control box.
4. Use the connector and the wire tie to reduce any slack
in the humidistat cable to ensure that it will not be
damaged by contact with the condenser coil (see Fig.
42).
5. Use wire nuts to connect humidistat cable to two
PINK leads in the low–voltage wiring as shown in
Fig. 44.
To connect the Edge Programmable Thermidistat
(T6- - PRH01- - A):
1. Route the Edge Programmable Thermidistat multi- -
conductor thermostat cable (field- - supplied) through
the bushing in the unit's louvered end panel (see Fig.
42).
2. Route the cable through the snap- - in wire tie and up to
the web bushing near the control box.
3. Feed the cable through the bushing and into the
bottom left side of the control box after removing one
of the two knockouts in the corner of the box. Use a
connector to protect the cable as it enters the control
box.
4. Use the connector and the wire tie to reduce any slack
in the thermostat cable to ensure that it will not be
damaged by contact with the condenser coil (see Fig.
42).
5. The Edge Programmable Thermidistat has dry
contacts at terminals D1 and D2 for dehumidification
operation (see Fig. 45). 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 the installation instructions included with the
Bryant Edge Programmable Thermidistat device for
more information.
