Perfect Humidityt Control Connections

Perfect Humidity - - Space RH Controller —
NOTE: Perfect Humidity is a factory installed option
which is only 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 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- - 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. Refer to the instructions for the field- - sup-
plied humidistat for more information.
To connect the Edge Programmable Thermidistat
(T6- - PRH01- - A):
1. Route the Edge Programmable Thermostat multi- -
conductor cable (field- - supplied) through the hole
provided in the unit corner post.
2. Feed wires through the raceway build 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 Edge Programmable Thermostat has dry contacts
at terminals D1 and D2 for dehumidification
operation (see Fig. 35). 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.
