Introduction 1.1 Applications 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) 1.2 Supplied Parts • 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) 1.3 Accessories • RC845 relay (see section 2.5) • AC146-410 plenum temperature sensor (see section 2.8) • CT241 telephone controller (see section 2.10) 2. Installation 2.1 Control Module (CT280-HP-2H1C) Install the control module on the furnace's electrical panel, away from the heat source. 2.2 User Console (TH146) 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). 2.3 Heat Pump 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 TH146-N-DE 400-280-000-G 9/22/06 1/8 • Controller terminal L to heat pump terminal L • Controller terminal W to heat pump terminal W (see section 2.5) • Controller terminal G to heat pump terminal G (see section 2.5) 2.4 24 V Transformer 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). 2.5 RC845 Relay 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. 2.6 Humidifier Connect the humidifier to controller terminals C and H (no polarity). 2.7 Outdoor Sensor (AC144-03) 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). 2.8 Plenum Sensor (AC146-410) 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). 2.9 Dual-energy Input 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. 2.10 Unoccupied Mode Input 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.

The first menu item (parameter) is dis played. 🞐 To 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. ❑ To modify a parameter, press either button. ❒ To exit the configuration menu, press . ⬧ Return the controller to User mode (USER) using the SW2 selector switch. 4. Principles of Operation 4.1 Automatic Heating/Cooling Changeover 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. 4.2 Balance Points 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. 4.3 Heating During Defrost 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. 4.4 Types of Heat Pump Installations 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. 4.5 "Smart Fan" 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). 4.6 Interstage Delay 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).

Ad (add-on): Use this setting when the indoor coils are located downstream of the auxiliary heat source. This is generally the case for add-on installations. nr (normal): Select this setting when the indoor coils are located upstream of the auxiliary heat source. This is generally the case for new installations. 6 Cycles per hour 2 to 6 4 Allows you to select the number of cycles per hour. It is recom mended to use the default setting except in exceptional cases. 7 "Smart fan" On / OF OF On: "smart fan" is On (see section 4.5). OF: "smart fan" is Off. 8 Interstage delay 5 to 90 min. 10 min. Set the interstage delay (see section 4.6). 9 Outdoor temperature display On / OF On Select between displaying the outdoor temperature or display ing the indoor humidity level. On: Displays the outdoor temperature. OF (Off): Displays the indoor humidity level. NOTE: To display the outdoor temperature, the outdoor sensor must be connected. 10 Humidifier operating mode HE / Fn HE HE (Heat): The humidifier can operate only when heating is activated. Fn (Fan): The humidifier can operate as long as the fan is run ning. NOTE: The humidifier is disabled when cooling is activated. 11 Automatic humidity adjustment On / OF OF Allows you to place the humidity adjustment to automatic mode. On (automatic): The humidity level is automatically regulated by the controller according to the outdoor temperature to avoid condensation or ice formation on windows (see item 12). OF (manual): The user manually sets the humidity level (see item 12). 12 Humidity setpoint 5% to 60% 5% Set the desired humidity level. This parameter is available only when the humidity control is placed in manual mode (see item 11). Humidity offset -9% to 9% 0% Allows the user to apply an offset to the automatic humidity con trol. For example, the user can enter a negative offset if there is still ice formation or condensation on the windows. This param eter is available only when the humidity control is placed in automatic mode (see item 11). NOTE: Only the humidity setpoint or humidity offset (item 12) is available when the controller is placed in user mode (SW2 switch).

Operation 5.1 System Operating Mode (Heating/Cooling) Press MODE to place the controller in one of the following modes. HEAT The system is in heating mode. COOL The system is in cooling mode. AUTO The system is in automatic changeover. (The system switches between heating mode and cooling mode to main tain the desired temperature.) OFF Both heating or cooling are off. EHEAT The system is in emergency heat mode. Only auxiliary heat ing is used when there is a call for heat. 5.2 Fan Operating Mode (On/Auto) 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. 5.3 Indoor Humidity / Outdoor Temperature Display 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. Outdoor temperatureIndoor 5.4 Temperature Adjustment 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. 5.5 Humidity Adjustment 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. One of the following displays appears: humidity TH146-N-DE 400-280-000-G 9/22/06 7/8 Humidity level set by user Offset set by user Humidity level set by controller 7.
