The Drivaire Ai Plus is an intelligent home ventilation system designed to maintain a healthy indoor environment by managing air flow, temperature, and humidity. This user guide, Version 1 - April 2010, outlines the system's features and operational instructions.

Function Description:

The Ai Plus system is a powerful and intelligent home ventilation solution that dynamically adjusts fan speed, heating elements, and air valves based on environmental conditions. It is designed to be a "set and forget" system, operating in the background to ensure a healthy home. The system can be configured to suit various house sizes and offers a full range of features through the initial Drivaire installer setup. Additional features can be added later using the same base system.

Key Operating Modes and Features:

• Maximum Roof Space Temperature Setting:

  • Purpose: To define the upper temperature limit for air drawn from the roof space.
  • Usage: Press and hold the SET button until "Set Roof Max" appears. Use the arrow buttons to adjust to the desired temperature (between 19°C and 50°C). Release the button, then press SET again to store the setting. If the roof space temperature exceeds this limit, the system will stop drawing air into the house and display "Too Hot."

• Minimum Roof Space Temperature Setting:

  • Purpose: To define the lower temperature limit for air drawn from the roof space.
  • Usage: Press and hold the SET button until "Set Roof Min" appears. Use the arrow buttons to adjust to the desired temperature (between 00°C and 14°C). Release the button, then press SET again to store the setting. If the roof space temperature falls below this limit, the system will stop drawing air into the house and display "Too Cold." If 00°C is selected, the unit will not shut off at any lower temperature.

• System ON/OFF:

  • Purpose: To manually turn the ventilation system on or off.
  • Usage: To turn ON, press and hold the power button for 2 seconds. To turn OFF, press and hold the power button for 2 seconds. In standard "positive pressure" mode, when ON, the unit will display "Air ON" and ventilate the home with any solar-heated air.

• AIR BOOST (Extreme Conditions Mode):

  • Purpose: To activate a temporary boost in air circulation during extreme conditions.
  • Usage: To turn ON, press and hold AIR BOOST for 2 seconds. To turn OFF, press and hold AIR BOOST for 2 seconds. When active, the keypad display will alternate between "AirBoost" and the system's current mode.

• Supplemental HEAT (if heater fitted):

  • Purpose: To activate and adjust the power level of an optional heating element.
  • Usage: Press and release the SET button. Use the arrow buttons to cycle through power levels (25%, 50%, 75%, Max). Release the button at the desired level, then press SET again to store the setting. For example, if a 2kW heater is fitted and 75% is selected, the output will be 1.5kW.
  • Room Thermostat Setting: To set the room thermostat, press and hold the SET button until "Room Heat Off" is displayed. Use the arrow buttons to adjust the desired temperature, release the button, then press SET again to store the setting.

• Heat Transfer (if transfer valve fitted):

  • Purpose: To transfer heat from a source (e.g., woodburner or heat pump) to other parts of the house.
  • Usage: Press and hold the SET button until "Set Warm Tfr" is displayed. Use the arrow buttons to adjust the desired temperature setting, release the button, then press SET again to store the setting. Heat transfer will begin when the temperature at the source rises to this setpoint. This feature allows the air valve to change and move air from the heat source to remote parts of the house.

• Cool Transfer (if transfer valve fitted):

  • Purpose: To transfer cool air from a source (e.g., heat pump in cooling mode) to other parts of the house.
  • Usage: Press and hold the MODE button until "Cool Tfr" is displayed. Then, press and hold the SET button until "Set Cool Tfr" is displayed. Use the arrow buttons to adjust the desired temperature setting, release the button, then press SET again to store the setting. Cool air transfer will begin when the temperature at the source lowers to this setpoint.

• Fresh Air (if fresh air valves fitted):

  • Purpose: To draw fresh air from outside.
  • Usage: Press and hold the MODE button until "FreshAir" is displayed. Then, press and hold the SET button until "FreshAir Off" is displayed. Use the arrow buttons to adjust the desired temperature setting, release the button, then press SET again to store the setting. The system will revert to positive pressure mode (drawing air from the roof space) when the temperature lowers to this setpoint.

• Return to Auto Warm (Normal Mode):

  • Purpose: To return the system to its default automatic warming mode.
  • Usage: Press and hold the MODE button until "AutoWarm" is displayed.

Technical Specifications (Implied):

• Temperature Range:
  • Maximum Roof Space: 19°C to 50°C
  • Minimum Roof Space: 00°C to 14°C
• Heater Power Levels (if fitted): 25%, 50%, 75%, Max (e.g., 1.5kW output for a 2kW heater at 75%).
• Control Interface: Keypad with SET, MODE, AIR BOOST, and arrow buttons.
• Display: Digital display for mode and temperature settings.

Usage Features:

• Intelligent Operation: Automatically adjusts fan speed, heating elements, and air valves based on environmental conditions.
• "Set and Forget" Design: Once configured, the system operates autonomously to maintain desired conditions.
• Expandable: Additional features can be integrated with the existing base system.
• Customizable: Settings for maximum/minimum roof space temperature, supplemental heat, and air transfer can be tailored to user preferences.

Maintenance Features:

The manual does not explicitly detail maintenance features. However, as an intelligent system, it is designed for continuous background operation, suggesting minimal direct user maintenance. Regular professional checks might be implied for optimal performance and longevity, especially given the "initial Drivaire installer setup" mentioned.
