Installation Guide
Non-programmable Heat Pump Controller
The TH146-N-DE electronic controller can be used to control a heat
pump system. The following devices can be connected to the con-
troller:
heat pump
auxiliary heating (furnace)
air recirculation fan
humidifier
dual-register meter (dual energy)
remote control device (for the unoccupied mode)
• CT280-HP-2H1C control module
• TH146 console with two wall anchors and mounting screws
• AC144-03 outdoor temperature sensor (3 m or 10 ft) with
mounting clip (see section 2.7)
• RC845 relay (see section 2.5)
• AC146-410 plenum temperature sensor (see section 2.8)
• CT241 telephone controller (see section 2.10)
Install the control module on the furnace’s electrical panel, away
from the heat source.
Install the console in the area where you wish to measure the tem-
perature and humidity. Avoid locations where there are air drafts
(e.g., top of staircase or air outlet) or stagnant air (behind a door).
Do not install the console on a wall hiding air ducts nor expose it to
direct sunlight.
NOTE: If this controller replaces an existing thermostat, the wires
that were connected to the thermostat can be used to connect the
console. The maximum wire length is 30 m (100 feet).
1) Choose a location about 5 ft. (1.5 m) above the floor on an
inside wall.
2) Loosen the captive screw under the console.
3) Detach the console from its base by pulling the bottom section.
4) Secure the base using the wall anchors and screws.
5) Connect the console to controller terminals TH and TH (no
polarity).
Connect the heat pump to the controller as follows:
• Controller terminals R and C to heat pump terminals R and C
(see section 2.4)
• Controller terminal Y to heat pump terminal Y
• Controller terminal O/B to heat pump terminal O
• Controller terminal WW to heat pump terminal WW

• Controller terminal G to heat pump terminal G (see section
2.5)
You might need a 24 V transformer if you have an add-on installa-
tion. Connect the transformer to the controller terminals R and C (24
Vac In).
If you have an add-on installation, you might need a relay such as
Aube’s RC845 to connect the furnace (auxiliary heating) and its fan
to the controller. Install the relay near the control module. Connect
the wires of the RC845 relay as follows:
• relay terminals W, G and C to controller terminals W, G and
C.
• relay terminals T and T to the appropriate furnace terminals:
T and T (oil); TH and TH (gas); R and W (electric).
NOTE: Refer to the relay’s installation instructions for more details.
Connect the humidifier to controller terminals C and H (no polarity).
The outdoor sensor is required for the following:
• balance points
• automatic humidity control
• outdoor temperature display
• defrost point
When installing the sensor, observe the following guidelines:
• Avoid locations where the sensor can be covered with snow
or exposed to direct sunlight.
• Avoid air outlets and concealed chimneys or stove pipes.
Install the sensor using its mounting clip and connect it to controller
terminals OS and CS (no polarity).
NOTE: The maximum wire length is 30 m (100 feet).
The plenum sensor measures the temperature inside the plenum.
This data is required for high pressure protection during the defrost
cycle (see section 4.3).
NOTE: The plenum sensor is generally needed for add-on installa-
tions only. It is not needed if the heat pump is not connected to the
controller terminal WW.
Install the sensor on the side of the plenum and
position it such that its aperture faces the air
flow.
Connect the sensor to controller terminals PS
and CS (no polarity). For more information,
refer to the instructions provided with the sen-
sor.
NOTE: The maximum wire length is 30 m (100
feet).
The dual-energy input can be connected to the dual-register meter
equipped with a normally open (NO) dry contact. Connect the termi-
nals DE and CC of the controller to the terminals (yellow and red
wires) of the dual-register meter.
When the contact is open, the heat pump and auxiliary heating
operate as usual. The contact closes when the outdoor temperature
drops below the set threshold. When the contact is closed, the heat
pump is disabled and only the auxiliary heat can be used.
To use the unoccupied mode, the controller requires a remote con-
trol device such as Aube’s telephone controller CT241 equipped
with a dry-contact output (normally open). The unoccupied mode is
activated when the contact closes. (See section 5.6.)
To access the 3 configuration switches, loosen the captive screw
under the console and separate the console from its base by pulling
it from the bottom part.

3.1 Switch Configuration
TH146-N-DE 400-280-000-G 9/22/06 3/8
3.1.1 Backlight (SW1)
BL ON: The screen is always backlit.
AUTO: The screen is backlit only when a button is pressed. The
backlight remains on for 12 seconds.
3.1.2 Access Mode (SW2)
INST: Installer mode. Gives access to all configuration parameters.
NOTE: In this mode, the short-cycle protection is disabled and
the interstage delay is reduced to 1 minute.
USER: User mode. Gives access to configuration parameter 12
(humidity setpoint or humidity offset) only.
3.1.3 Keypad Lock (SW3)
I: The keypad is locked. Settings cannot be changed.
O: The keypad is unlocked.
nPlace the controller in Installer mode (INST) using the SW2
selector switch on the back of the console.
oPress the Mode button for 3 seconds to access the configura-
tion menu (see page 4). The first menu item (parameter) is dis-
played.
pTo view another menu item, briefly press the Mode button.
The following table shows the order in which the parameters
appear as well as a description of each parameter.
qTo modify a parameter, press either button.
rTo exit the configuration menu, press .
sReturn the controller to User mode (USER) using the SW2
selector switch.
With automatic heating/cooling mode changeover, there’s no need
to adjust the controller at every change of season or weather condi-
tion. The controller switches automatically between heating mode
and cooling mode to maintain the desired temperature. The mode
changeover occurs as follows:
• The controller switches to cooling mode when the indoor tem-
perature is higher than the setpoint by more than 1.5°C (2.5°F)
for 15 minutes.
• The controller switches to heating mode when the indoor tem-
perature is lower than the setpoint by more than 1.5°C (2.5°F)
for 15 minutes.
Balance points are used to disable the heat pump operation or aux-
iliary heating below or above a certain temperature.
• When the outdoor temperature is below the balance point low
(bP L), the heat pump is disabled and only auxiliary heating can
be used (see page 4, item 2).
• When the outdoor temperature is above the balance point high
(bP H), the auxiliary heat is disabled (see page 4, item 3) and
only the heat pump can be used.
NOTE: Balance points will not work if the AC144-03 outdoor tem-
perature sensor is not connected to the controller.
The auxiliary heat is activated during defrost except under the fol-
lowing conditions:
• When the outdoor temperature is above the defrost point (see
page 4, item 4). NOTE: This condition will not apply if the
AC144-03 outdoor sensor is not connected to the controller.
• When the plenum temperature is above 40°C (104°F). The
auxiliary heat is re-activated when the plenum temperature
drops below 32°C (90°F). NOTE: This condition will not apply if
the AC146-410 plenum sensor is not connected to the control-
ler.
NOTE: The auxiliary heat’s short-cycle protection is disabled during
defrost.
The controller can be configured for either of the following types of
heat pump installations (see page 4, item 5).
•Add-on Installation: This type of installation is performed
when adding a heat pump to an existing furnace. When the
heat pump is installed, the furnace becomes the auxiliary heat
source. In this type of installation, the indoor coils are usually
installed downstream of the auxiliary heat source. When the
controller is configured for an add-on installation, the heat
pump is disabled during auxiliary heating to prevent overpres-
sure.
•New Installation: In this type of installation, as there is not
already a furnace, the auxiliary heat source is installed at the
same time as the heat pump. In this type of installation, the
indoor coils are located upstream of the auxiliary heat. When
the controller is configured for a new installation, the heat pump
and the auxiliary heat can operate simultaneously.
When “smart fan” is enabled (see page 4, item 7), the fan operates
as follows:
• During the unoccupied mode (i.e., when you are away from
home), the fan operates only when heating or cooling is acti-
vated.
• The fan operates continuously the rest of the time.
NOTE: “Smart fan” is useful only when the fan is set to On (see sec-
tion 5.2).
The interstage delay is the time that the temperature has to return to
an acceptable value when it deviates too much from the setpoint.
After this delay, auxiliary heating is activated. Auxiliary heating will
be deactivated once the temperature returns to an acceptable value
(see page 4, item 8).

Press MODE to place the controller in one of the following modes.
Press the button to select the fan operating mode.
• In automatic mode, the fan runs only when heating or cooling is
activated.
• In continuous mode, the fan runs continuously and the sym-
bol is displayed. NOTE: If the “smart fan” feature is enabled,
the fan will run only when heating or cooling will be activated
during unoccupied mode.
Depending on how the controller has been configured (see page 4,
item 9), it displays either the measured indoor humidity level or the
measured outdoor temperature.
The actual (measured) temperature is normally displayed. To view
the temperature setpoint, press one of the buttons once. The
setpoint is displayed for 5 seconds and is indicated by the sym-
bol.
To modify the temperature setpoint, press one of the buttons
until the desired temperature is displayed.
NOTE: If the controller is in automatic heat/cool changeover, the
setpoint is automatically reduced or raised by 1°C (2°F) when the
controller switches to heating mode or to cooling mode respectively.
For example, if you place the setpoint at 24°C (75°F) while in heat-
ing mode, the setpoint will become 25°C (77°F) in cooling mode and
will return to 24°C (75°F) when the controller switches back to heat-
ing mode.
The humidity adjustment can be placed in manual mode or in auto-
matic mode (see page 4, item 11).
Manual Adjustment
In manual mode, the user sets the humidity level (5% to 60%).
Automatic Adjustment
In automatic mode, the controller sets the humidity level based on
the outdoor temperature to prevent ice formation or condensation
on windows. However, the user can apply an offset (-9% to 9%). For
example, the user can enter a negative offset if there is too much
condensation on the windows.
Procedure
The procedure to set the humidity level (in manual mode) or the off-
set (in automatic mode) is as follows:
1) Press the Mode button for 3 seconds.

3) Press the button to exit.
The symbol is displayed when the humidifier is On.
The controller can be placed in unoccupied mode via a remote con-
trol device such as Aube’s CT241 telephone controller (see section
2.10). In this mode, the setpoint is set back by 4.5°C (8°F); it is low-
ered in heating mode or raised in cooling mode. The icon
appears during the unoccupied mode.
NOTE: Automatic changeover is disabled during the unoccupied
mode.
If you change the temperature setpoint (using the buttons) in
unoccupied mode, the controller temporarily bypasses the current
setpoint. The new setpoint will be maintained for 2 hours, after
which the controller will return to the previous setpoint. The icon
flashes during the bypass.
