aube TH146-P-2H1C Programmable Thermostat Installation Guide Overview

Summary of Contents

• Page 1: Installation guide for the programmable 2H1C controller outlines essential components and installation instructions. The TH146-P-2H1C programmable controller is compatible with various heating and cooling systems, including heat pumps and HVAC systems. The control module (CT280-2H1C) should be configured using DIP switches based on the specific heating/cooling system. Devices that can connect to the controller include an air recirculation fan, humidifier, dual-register meter, and remote control device. Supplied parts include the CT280-2H1C control module, TH146-P console, and AC144-03 outdoor temperature sensor. The control module should be installed near the heating/cooling system, away from heat sources. The user console (TH146-P) should be installed centrally, avoiding drafts and stagnant air areas. If replacing an old thermostat, two of the existing wires can be used to connect the user console to the control module. The maximum wiring length for the connection is 30 m (100 ft). Accessories available include the RC845 relay, AC146-410 plenum temperature sensor, CT241 telephone controller, and AC130-12 wall plate.
• Page 2: Install the sensor on the side of the plenum and position it such that its aperture faces the air flow. Choose a location about 1.5 m (5 ft) above the floor on an inside wall. The dual-energy input can be used only with a heat pump equipped with auxiliary heat. If you have an add-on installation, you might need an RC845 relay to connect the furnace and its fan to the controller. To use the unoccupied mode, the controller requires a remote control device such as Aube’s CT241 telephone controller. The outdoor sensor is required for outdoor temperature display, balance points, defrost point, and automatic humidity control. The plenum sensor is required for low temperature limit, high temperature limit, and fan limit if gas heating is used. Access the configuration switches by loosening the captive screw under the console. The keypad can be locked or unlocked to control access to settings. Place the console in Installer mode to access the configuration menu.
• Page 3: Types of heat pump installations include add-on installation and new installation. Add-on installation involves adding a heat pump to an existing furnace, making the furnace the auxiliary heat source. New installation occurs when there is no existing furnace, and the auxiliary heat source is installed simultaneously with the heat pump. Automatic heating/cooling changeover allows the controller to switch modes without manual adjustment. In manual mode, the controller switches modes based on temperature deviations from setpoints. Interstage delay is the time allocated for temperature to return to an acceptable value before activating the next heating or cooling stage. Low and high temperature limits prevent the plenum from becoming too cold or too hot. Balance points disable the heat pump or auxiliary heating based on outdoor temperature thresholds. Smart fan operates under specific conditions to optimize heating and cooling efficiency. Heating during defrost activates auxiliary heat except under certain conditions.
• Page 4: Wiring tables for heat pump configurations are provided. Connect the console between the TH terminals with no polarity. Connect the plenum sensor between the PS and CS terminals with no polarity. Common terminal for the plenum sensor and the outdoor sensor is indicated. Connect the outdoor sensor between the CS and OS terminals with no polarity. Connect the dual-register meter between the DE and CC terminals with no polarity. Common terminal for the dual-energy meter and the unoccupied mode input is specified. Connect a dry contact between the UN and CC terminals with no polarity. Connect the humidifier between the H terminals using a dry contact. Common terminal for the unoccupied mode input is noted.
• Page 5: Wiring diagram for 2H1C heat pump - new installation. Components include compressor, auxiliary heat, and reversing valve. References to AC146-410 and AC144-03. Mention of dual energy and CT241. Includes fan, fault, humidifier, and defrost functions. Model TH146-P-2H1C is specified. Document version dated 5/23/07. Additional reference number 400-280-014-A. Date noted as 5/11.

• Page 7: Wiring diagram for HVAC systems. Cooling unit specifications. Heating unit specifications. Fan specifications. Humidifier specifications. Model numbers listed include AC146-410 and AC144-03. CT241 and TH146-P-2H1C are also mentioned. Document version date is 5/23/07. Additional date noted is 7/11.
• Page 8: Configuration Menu Select the time display format. Early Start applies for periods 1 and 3 (P1 and P3) only. Automatic daylight savings adjustment. Set the bP L limit. Set the bP H limit. Set the defrost point temperature. Set according to the type of heat pump installation. Set the interstage delay for the auxiliary stage. Select the number of heating/cooling cycles per hour. This setting determines the fan operation in automatic mode when the system is in heating mode.
• Page 9: User’s guide for the programmable H/C controller includes important features such as indicator LEDs for system status. The system fault indicator alerts users to any issues, while emergency heat mode and dual energy modes are also indicated. Key settings include time and day configuration, temperature adjustment, and mode selection for both the system and fan operation. The controller allows for indoor and outdoor temperature readings, as well as indoor humidity settings. The display remains lit for 12 seconds when any button is pressed, and it stays lit during configuration. Users can set the clock and date by pressing the clock button and following the prompts to adjust hours, minutes, and days. The controller displays the measured indoor temperature, with the setpoint viewable for a limited time when a button is pressed. System operating modes include heating, cooling, automatic changeover, and off settings, with specific notes for gas-operated HVAC systems. The fan operating mode can be selected, with options for continuous or automatic operation based on heating or cooling activation. Emergency heat mode utilizes only auxiliary heating when needed, applicable for systems connected to heat pumps.
• Page 10: Temperature adjustment allows for manual or automatic settings. In manual adjustment mode, users can set the temperature directly. Automatic adjustment mode follows a programmed schedule for temperature control. A pre-programmed schedule includes heating and cooling setpoints for each period. Temporary bypass allows for a two-hour adjustment while in automatic mode. Unoccupied mode lowers heating or raises cooling temperatures when activated. Programming can accommodate up to four periods per day with customizable settings. Automatic changeover is disabled during unoccupied mode. Users can skip periods in the schedule by using the clear function. The cooling setpoint must always be higher than the heating setpoint by at least 1°C.
• Page 11: Humidity setpoint range: 5 to 60%. Temperature setpoint range for heating mode: 5°C to 30°C. Temperature setpoint range for cooling mode: 15°C to 40°C. Indoor temperature display range: 0°C to 70°C. Outdoor temperature display range: -50°C to 70°C. Warranty period: three years from the date of purchase. Manual adjustment allows the user to set the humidity level. Automatic adjustment is based on outdoor temperature to prevent ice formation. This warranty does not cover removal or reinstallation costs. Aube's sole responsibility is to repair or replace the product within the warranty terms.
