Heat pump HVAC Install the control module near the heating/cooling system, away from any heat source. 2.2 User Console (TH146-P) Install the console in a central location. Avoid locations with 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 old thermostat, any two of the wires that were connected to the thermostat can be used to connect the user console to the control module. The maximum wiring length is 30 m (100 ft). TH146-P-U 400-280-010-B 5/24/07 1/12 ■ Choose a location about 1.5 m (5 ft) above the floor on an inside wall. □ Loosen the captive screw under the console. 🞐 Detach the console from its base by pulling the bottom section. ❑ Secure the base using the wall anchors and screws. ❒ Connect the console to controller terminals TH and TH (no polarity). 2.3 Heating/Cooling System The terminals used to connect the heating/cooling system depend on the type of system. See the appropriate wiring table on page 4. 2.4 RC845 Relay If you have an add-on installation, you might need an RC845 relay to connect the furnace (auxiliary heating) and its fan to the control ler. Install the relay near the control module and connect the wires as follows: • relay terminals W, G and C to controller terminals W1, 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. If you have a 3H1C or 4H2C heat pump, a second RC845 relay might be required to connect the second auxiliary heat. 2.5 Humidifier Connect the humidifier in series with the power supply between controller terminals H and H (dry contact). 2.6 Dehumidifier / Air Exchanger Connect the dehumidifier or air exchanger in series with the power supply between controller terminals D and D (dry contact). 2.7 Outdoor Sensor (AC144-03) The outdoor sensor is required for the following: • outdoor temperature display • balance points (heat pumps only, see section 4.2) • defrost point (heat pumps only, see section 4.3) • automatic humidity control (see section 7.2) • use of an air exchanger (see section 4.10) 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 wiring length is 30 m (100 ft). 2.8 Plenum Sensor (AC146-410) The plenum sensor is required for the following: • low temperature limit inside the plenum (HVAC only) • high temperature limit inside the plenum (HVAC only) • fan limit if gas heating is used (HVAC only) • high pressure protection during defrost cycle (This protection is generally needed for add-on installations 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 wiring length is 30 m (100 ft). 2.9 Dual-energy Input NOTE: The dual-energy input can be used only with a heat pump equipped with auxiliary heat. The dual-energy input can be connected to the dual-register meter equipped with a normally open (NO) dry contact. Connect the con troller terminals DE and CC to the meter terminals (yellow and red wires). The contact closes when the outdoor temperature drops below the temperature setting on the meter. 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 CT241 telephone controller equipped with a normally open (NO) dry contact placed between terminals UN and CC of the controller. The unoccupied mode is activated when the contact closes. (See section 6.4.) 3.

TH146-P-U 400-280-010-B 5/24/07 2/12 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 condition. The controller switches automatically between heating mode and cooling mode to maintain the desired temperature. Manual Mode When the controller is in manual mode, the heating/cooling mode changeover occurs as follows: • The controller switches to cooling mode when the indoor temperature is higher than the setpoint by more than 1.5°C (2.5°F) for 15 minutes. • The controller switches the heating mode when the indoor temperature is lower than the setpoint by more than 1.5°C (2.5°F) for 15 minutes. Automatic Mode When the controller is in automatic mode, it follows the programmed sched ule. Two temperature settings (heating setpoint and cooling setpoint) are programmed for each period of the schedule. The heating/cooling mode changeover occurs as follows: • When the controller is in heating mode, the indoor temperature is main tained at the heating setpoint. However, if the temperature rises and remains above the cooling setpoint for 15 minutes, the controller will switch to cooling mode. • When the controller is in cooling mode, the indoor temperature is main tained at the cooling setpoint. However, if the temperature drops and remains below the heating setpoint for 15 minutes, the controller will switch to heating mode. 4.2 Balance Points (heat pumps only) Balance Points are used to disable the heat pump or the auxiliary heating when the outdoor temperature is below or above a set 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 8, item 5). • When the outdoor temperature is above the Balance Point High (bP H), the auxiliary heat is disabled and only the heat pump can be used (see page 8, item 6). NOTE: Balance Points cannot be used if the AC144-03 outdoor temperature sensor is not connected to the controller. 4.3 Heating During Defrost (heat pumps only) The auxiliary heat is activated during defrost except under the following con ditions: • When the outdoor temperature is above the defrost point (see page 8, item 7). Note: This condition will not apply if the AC144-03 outdoor sen sor 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 controller. 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 8, item 8). • 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 installa tion, the indoor coils are usually installed downstream of the auxiliary heat source. When the controller is configured for an add-on installa tion, the heat pump is disabled during auxiliary heating to prevent over pressure. • 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 Interstage Delay Interstage Delay is the time allocated for the temperature to return to an acceptable value when it deviates too far from the setpoint. If this time has elapsed, the next heating or cooling stage is activated. The heating or cool ing stage will be deactivated when the temperature returns to an acceptable value. The Interstage Delay is fixed at 4 minutes if the controller is config ured for an HVAC system and is user-adjustable if it is configured for a heat pump (see page 8, item 9). 4.6 Low and High Temperature Limits Low Temperature Limit (LLMT) and High Temperature Limit (HLMT) are used to keep the plenum from becoming too cold or too hot. During cooling, if the plenum temperature is lower than LLMT, a cooling stage is deactivated starting with the one that was last activated. If, after a while, the temperature is still too low, another cooling stage is deactivated and so on. Likewise, dur ing heating, if the plenum temperature is higher than HLMT, a heating stage is deactivated starting with the one that was last activated. If, after a while, the temperature is still too high, another heating stage is deactivated and so on. (see page 8, items 10 and 11.) WARNING: LLMT and HLMT can be used in parallel with an UL353- approved device but they do not replace such device. NOTE: LLMT and HLMT cannot be used if the plenum temperature sensor is not connected to the controller. 4.7 Smart Fan When Smart Fan is enabled (see page 8, item 15), the fan operates as fol lows: • During periods 2 and 4 of automatic mode and during the unoccupied mode (i.e., when you are away from home or sleeping), the fan oper ates only when heating or cooling is activated. • The fan operates continuously the rest of the time. NOTE: For Smart Fan to work, set the fan to On (see section 5.3). 4.8 Automatic Humidification / Dehumidification Changeover If a humidifier and a dehumidifier are both connected to the controller, the controller will automatically switch between the two devices to maintain the desired humidity level. The changeover occurs when the humidity deviates from the setpoint by more than 3% for 30 minutes. 4.9 Dehumidification by Droop Dehumidification by droop is a method of dehumidification without using a dehumidifier. This method is possible only if your system has a cooling stage. When this feature is enabled (see page 8, item 18), if the humidity level is too high, the temperature is temporarily lowered below the setpoint to reduce the indoor humidity level. NOTE: Dehumidification by droop can cause overcooling. 4.10 Dehumidification by Air Exchanger Dehumidification using an air exchanger will not be efficient if the outdoor temperature is too high. When an air exchanger is used, the controller will disable dehumidification if the outdoor temperature is NOT lower than the indoor temperature by more than 5°C (9°F). When this occurs, the message HIGH TEMP is displayed.
