RECOGNIZE THIS SYMBOL AS A SAFETY PRECAUTION.
ATTENTION INSTALLING PERSONNEL
As a professional installer you have an obligation to
know the product better than the customer. This
includes all safety precautions and related items.
Remember, it is your responsibility to install the
product safely and to know it well enough to be able
to instruct a customer in its safe use.
Prior to actual installation, thoroughly familiarize
yourself with this Instruction Manual. Pay special
attention to all safety warnings. Often during
installation or repair it is possible to place yourself
in a position which is more hazardous than when
the unit is in operation.
Safety is a matter of common sense...a matter of
thinking before acting. Most dealers have a list of
specific good safety practices...follow them.
May 1998 Rev. 1
The precautions listed in this Installation Manual
are intended as supplemental to existing practices.
However, if there is a direct conflict between existing
practices and the content of this manual, the
precautions listed here take precedence.

General
Installation
These ambient temperature control thermostats can be
employed in conjunction with the room thermostat to control the electric heaters that have been added to Amana
heat pump or cooling systems. The purpose of an ambient
thermostat is to limit the amount of electric heat to more
closely match with the building loss.
REMOTE HEAT PUMPS
The ambient thermostat is designed to be installed in the
space allocated in the control box of the remote units
(Figures 2-5).
Description
WARNING
To avoid possible electrical shock, injury
or death; disconnect the electrical power
before installing the ambient thermostat(s).
ATK01
This kit includes an ambient thermostat mounted in a
weatherproof box for installation exterior to the unit. This kit
is used for ambient control on all Amana package models
and remote cooling models, including air conditioning and
heat pump package units.
1. Remove unit control panel cover by taking out the sheet
metal screws that secure it.
2. Install the ATK thermostat in the existing holes in the
control box, as shown in the following photographs.
3. RHA**B3 models will require two (2), 7/64” holes to be
drilled in dimple locations (See Figure 7).
4. Place the ATK in the proper location and secure the
bracket with two (2) sheet metal screws provided.
5. For wiring connections, consult the outdoor unit wiring
diagram, or turn to the appropriate page in this manual.
6. Set thermostat(s) to the proper outdoor temperature.
7. Reinstall the service door to the control box.
ATK04 (SPECIAL APPLICATION ONLY)
This kit is the same as the ATK01 except that the thermostat has a maximum setting of 25°F. This kit is required
when installing 24.0 or 28.8 kW electric heat in the SPHO48
or 60 models.
ATK06
This kit includes an ambient thermostat and mounting
bracket. It can be installed in the control boxes of Amana
ARHF, ERHF, SRHF, ZRHF, RHA, RHD, and RHE remote
heat pumps. This kit is also used to control additional
heaters for all applications; add to the control box of Amana
remote heat pumps; add to the weatherproof box (ATK01,
ATK04) of Amana package and remote cooling models.
The ATK06 thermostat has a maximum setting of 25°F and
is required when installing 24.0 or 28.8 kW electric heat with
the SRHF42-48 or ERHF42-60 models.

PACKAGE UNITS (PH*’S )
The ambient thermostats used with package units are
available with a separate weatherproof box as shown in
Figure 1 (ATK01, ATK04).
WARNING
To avoid possible electrical shock, injury
or death; disconnect the electrical power
before installing the ambient thermostat(s).
1. For package units, select a location for mounting the
control box on the right hand side of the unit (See Figure
6) .

2. When an additional weatherproof box is required
(ATK01 or ATK04), select a location on the right side of
the unit most convenient for your application.
3. Attach the mounting brackets to the back of the weatherproof box with 1/4" screws provided.
4. Attach the box to the appropriate location by using two
self-drilling 1/4" screws.
5. Using an appropriate length of 24V control wire, route
the control wires through the low-voltage entrance.
Consult the wiring diagram in the package unit or the
appropriate page in this manual to connect the thermostats to the remainder of the system.
6. Set thermostat to proper outdoor temperature.
WARNING
To avoid possible electrical shock, injury
or death; disconnect the electrical power
before installing the ambient thermostat(s).
1. Remove unit control panel cover by taking out the sheet
metal screws that secure it.
2. Install the ATK thermostat in the existing holes in the
control box, as shown in Figures 2, 4, or 5.
3. RCB**B3* will require two (2), 7/64” holes to be drilled
in dimple locations (See Figure 7).
4. Place the ATK in the proper location and secure the
bracket with two (2) sheet metal screws provided.
5. For wiring connections, consult the outdoor unit wiring
diagram, or turn to the appropriate page in this manual.
6. Set thermostat(s) to the proper outdoor temperature.
7. Reinstall the service door to the control box.

heaters, is to be used:
1. Disconnect power.
2. Remove and save wire nut shown above.
3. Extend GY42 wire into the low voltage terminal area.
4. Connect the GY42 wire as shown on the wiring schematic for your system.
5. Wire nut and tape the unused GY41 wire to prevent shorts.

EXAMPLE APPLICATION OF A HEAT PUMP SYSTEM
FIGURE 9
Graph of Building Load and Unit Capacity
EXAMPLE APPLICATION OF A HEAT PUMP SYSTEM
1. Use maual J or Right-J or equivalent to calculate the
building’s heating and cooling loads at design conditions. In this example, the building load has been
calculated to be 110 MBh at design conditions of -8°F.
2. The building load can be plotted as in Figure 9. The
load is assumed to decline linearly from the design
condition to 0 MBh at an ambient temperature of 65°F.
The building load can also be tabulated, as in Figure 10.
3. Select the heat pump size to meet the cooling load.
4. Plot theheating capacity of the heat pump as in Figure
9, and tabulated in figure 10. The unit heating capacity
at various outdoor temperatures can be from the units
“Specification Sheet.”
5. Examination of the graph or table shows that the heat
pump alone is far below having enough capacity to
meet the design load at -8°F. Supplemental electric
heat needs to be installed which, combined with the
heat pump, will nearly match the house load.
6. Each bank of 9.6 kW of supplemental electric heat
adds aproximately 32.7 MBh of heating capacity to the
total system. The table in Figure 10 has columns for
each 9.6 kW added to the system. The graph, Figure
9, has parallel curves for each 9.6 kW added to the
system.
7. Installation of an outdoor thermostat is optional and
depends on how the heaters can be staged. The table,
Figure 8, shows available staging on EHK20 through
EHK30 heaters. Staging of electric heaters in the
BBA02A or BBC02A is performed automatically by the
blower control board, and can not be broken out individually.
8. Observing the graph in this example, 28.8 kW have
been installed. If the electric heater is an EHK30, only
the last 9.6 kW can be controlled by an ATK05 or
ATK06. The temperature setting on the ATK would be
approximately 7°F The room thermostat would control
the first two, 9.6 kW banks when the 37 degree balance
point is reached..
NOTE: Fan motor speed and room thermostat heat anticipators may need adjustment to match unit size and amount
of electric heat. See unit and heater kit wiring diagrams.
