Summary of Contents

• Page 1: TH150 Series electronic thermostat is designed for low-voltage pressure-dependent variable air volume (VAV) applications. It comes in four different models: TH150-1A, TH150-1F, TH150-1A2T, and TH150-1F2T. Depending on the model, the TH150 thermostat can have up to three outputs connected to various control devices. The designations of the terminals vary according to the particular model of thermostat. Remove the thermostat from its base by unscrewing the captive screw and tilting the bottom of the thermostat up. Pass the wires through the center hole of the base and secure the base to the wall or onto an electrical box. Wire the thermostat according to the terminal designations and typical wiring diagrams. To configure the terminals, refer to the appropriate section in the manual. The installation section includes mounting instructions and terminal designations. The document provides information on accessories compatible with the thermostat.
• Page 2: Typical applications include damper control with electric reheat and auxiliary baseboard heating, as well as hot-water heating. Figures illustrate various damper control setups, including automatic changeover and temperature control of fresh air supply. Caution is advised against connecting common to ground. Different configurations for changeover and NSB inputs are shown, including those sharing the same 24-Vac transformer and those using different transformers.
• Page 3: Configuration Remove the thermostat from its base and set the SW2 switch to MENU. Reinstall the thermostat. The thermostat is now in configuration mode. The first digit flashes to indicate that the first item of the menu can now be modified. To modify the setting, use the up/down arrows. Press Override to save the new setting and go to the next item. When the configuration is done, set the SW2 switch back to NORMAL. Factory settings are inside the shaded cells. Default value is 35°C (95°F) for maximum setpoint and 10°C (50°F) for minimum setpoint. If Output 2 type is set to 0-4, set the SW6 switch to Triac. If the output type is set to 5-8, set the switch to Analog.
• Page 4: The following table shows the different default modes and output types for Output 1, along with their corresponding settings in the configuration menu. The following table shows the different thermostat applications and their corresponding settings in the configuration menu. To control the ambient temperature using the internal sensor. To control the ambient temperature using the AC144-03 temperature sensor. To control the temperature at the air return using the AC146-410 temperature sensor. The minimum damper opening can be set between 0 and 50%. It is not recommended to set the minimum damper opening to 0% when a duct heater is connected to Output 2 or 3. The damper opening time can be set between 80 and 160 seconds. Output 2 controls heating only, regardless of the thermostat’s mode. Output 1 is used to control a damper, heating in heat mode or cooling in cool mode. The default mode is the thermostat’s mode at power-up.
• Page 5: Output types for Output 3 and their corresponding settings in the configuration menu are detailed. Three switches at the back of the control module are used to select various options. Temperature display can be set to either °C or °F. Access mode can be set to NORM for normal display or MENU for configuration. Output 2 type can be set to Analog or Triac, with a warning to ensure the switch matches the connected device type. Upon power-up, the thermostat undergoes a series of tests before displaying the actual temperature. The backlight can be turned on by pressing any button, illuminating the display for 12 seconds. The thermostat displays the actual temperature, with the ability to view and change the setpoint. The temperature setpoint automatically adjusts when switching between heating and cooling modes. The bar graph represents the voltage for an analog output or the duty cycle for a triac output, showing Output 1 power.
• Page 6: Mode changeover allows the thermostat to switch between heat and cool modes. The thermostat operates on 24 VAC with a current consumption of 25 mA. Output ratings include automatic changeover and changeover input with specific maximum ratings for Triac and analog outputs. The setpoint range is from 10°C to 35°C (50°F to 95°F) with a temperature display range of 0°C to 60°C (32°F to 140°F). Automatic changeover detects temperature differences to switch modes accordingly. The Night Setback mode lowers or raises temperature based on the set NSB value. Aube provides a three-year warranty against defects in workmanship or materials. Error codes indicate issues with internal or external temperature sensors. The warranty does not cover removal or reinstallation costs and is limited to repair or replacement. Specific legal rights may vary by province, state, or region.
