IMPORTANT - These instructions are intended for the use of
qualified individuals specially trained and experienced in
installation of this type of equipment and related system com-
ponents.
Improper installation may damage equipment, can
create a shock hazard, and will void the warranty.
NOTE: The words "Shall" or "Must" indicate a requirement
which is essential to satisfactory and safe product perfor-
mance.
The words "Should" or "May" indicate a recommendation or
advice which is not essential and not required but which may
be useful or helpful.
Installation and service personnel are required by some
states to be licensed.
Persons not qualified shall not install this equipment or inter-
pret these instructions.
APPLICATION
These outdoor thermostat accessories may be used with
heat pump series BRH(S,Q), DRH(S,Q), ERH(S,Q), FRHS,
BH(Q), DH(Q), FH, PHP, JP/PHP 13 SEER. The single
thermostat is used with systems having 5 - 10 KW electric
heat. The dual thermostat is used with systems having 15KW
or more electric heat. The function of the outdoor thermostat
accessory is to prevent the use of unneeded auxiliary electric
heat when the heat pump capacity is sufficient to meet the
home heating requirement, thus saving energy and utility
costs. Note that the auxiliary electric heat operates in
response to the second stage of the wall thermostat, and that
the outdoor thermostat(s) is wired in series with the second
stage. When adjusted to the correct setting(s), the outdoor
thermostat(s) prevents the operation of the auxiliary electric
heat at temperatures above the setting(s). Through the
contacts of the emergency heat relay, located in the outdoor
thermostat accessory, the outdoor thermostat(s) are by-
passed, placing the control of the electric heat solely in
response of the wall thermostat's second stage.
The emergency heat relay is energized by one of the
following occurrences:
• The system switch of the wall thermostat is placed
in the "emergency heat" position.
• The system's compressor is locked out due to a
high temperature or a high pressure limit tripping
action.
The setting(s) of the outdoor thermostat(s) is described
in a later section of these instructions.

INSTALLATION
,WARNING
SHOCK HAZARD -Disconnect electric power to
equipment before installation to prevent equipment
damage and possible personal injury.
LOCATION
This accessory is designed to be installed in an outdoor
environment. However, constant shade is the determining
factor in selecting a location for the outdoor thermostat.
Radiant heat from direct rays of the sun could affect the
operation of the thermostat.
There may be some heat pump models that provide an
attachment location for the outdoor thermostat, most models
do not. Careful selection should be used in locating the
outdoor thermostat. The electric cable provided is long
enough to allow the thermostat to be mounted on a nearby
structure.
WIRING
Route the electrical cable through the low voltage hole
provided in the outdoor heat pump.
Connect the cable wiring per the wiring diagram that pertains
to the application as listed below.
Use Figures 1 (single thermostat) or 2 (dual thermostat) for
applications with BRHS, DRHS, FRHS, BH(Q), DH (Q), or
BH(Q) model series with a revision code of "D" or higher at
the end of the model number.
Use Figure 3 for applications with BRHQ and DRHQ model
series with a revision code of "D" or higher at the end of the
model number.
For all models listed below, modification of the wiring in the
outdoor thermostat assembly will be required. Follow the
dashed optional lines in wiring diagrams for details.
Use Figures 4 (single thermostat) or 5 (dual thermostat) for
applications with PHP packaged heat pump.
Use Figures 6 (single thermostat) or 7 (dual thermostat) for
applications with JP/PHP 13 SEER packaged heat pumps.
Use Figures 8 (dual thermostat) or 9 (single thermostat) for
applications with FRHS model series with a revision code of
"A", "B", or "C" at the end of the model number.
Use Figures 10 (dual thermostat) or 11 (single thermostat) for
applications with BRH(S,Q), DRH(S,Q), BH(Q), DH(Q) model
series with a revision code of "A", "B", or "C" at the end of the
model number.
Use Figures 13, 14, 15, and 16 for applications with ERHS
and ERHQ units using demand - defrost board.

OUTDOOR THERMOSTAT(S) BALANCE
POINT TEMPERATURE ADJUSTMENT
FOR THE HOME
Determine the first balance point:
Before setting the outdoor thermostat, a heat loss calculation
must be made of the home. The heat loss of a home is
assumed to be linear and inversely proportionate to the
outdoor temperature. As the outdoor temperature drops, the
heat loss of the home increases. Conversely the heat pump
capacity is reduced as the outdoor temperature drops. At
some outdoor temperature, the heat pump capacity will
balance with the homes heat loss. In other words, at that
point, the heat loss of the home will be identical to the amount
of heat produced by the heat pump.
In order to determine the exact balance point, it is necessary
to chart the heat loss against the capacity of the heat pump.
See the heat pump Tabular Data Sheet for capacity
information at various outdoor temperatures. Chart the
capacities of the heat pump at the corresponding outdoor
temperatures on a graph and connect the points. See
example chart. The vertical axis represents BTU's (in
thousands) and the horizontal axis represents outdoor
temperature.
For the purpose of this example, let us assume that the
calculated heat loss of the home is 50,800 BTU's per hour at
an outdoor design temperature of + 10 °F. Moving up the
vertical axis, at 10° F, locate the number of BTU's per hour
heat loss and mark that point on the graph. Placing a straight
edge on this point, and aligning with the 70 ° F (the normal
indoor comfort condition) in the lower right-hand corner,
connect these two points with a straight line. Locate the point
at which the heat loss crosses the capacity curve of the heat
pump. This intersection is the balance point temperature for
the example application. This is the only balance point
needed for applying the single thermostat model and is the
first balance point when applying the dual thermostat model.
Determining the second balance point:
On the vertical axis at the first balance point, add 22,000
BTU's which is the capacity of the electrical heating
elements, and mark this point. This represents the combined
capacity of the heat pump and the electric elements. From
this point draw a line parallel to the heat pump capacity
curve. Where this new line intersects the heat loss line is the
second balance point.
Remove the outdoor thermostat cover, and set
thermostat(s):
It is advisable to set the thermostat(s) 3 degrees above the
determined balance point(s) so that the thermostat(s) are
closed before the wall thermostat's second stage calls for
heat. The outdoor thermostats are factory set at 30 degrees
(for the single thermostat model and #1 thermostat on the
dual thermostat model.) and 20 degrees (for the #2
thermostat on the dual thermostat model.) For this example,
adjust the #1 thermostat by aligning the screw slot on 32
degrees, adjust the #2 thermostat so that the screw slot
aligns with 10 degrees. Replace cover.
