The Aprilaire 8800 and legacy 8870 thermostat systems provide comprehensive HVAC control. In addition, they can be connected to a wide network of remote temperature and humidity sensors.

Driver Features

  • Supports up to 64 Aprilaire 8800 and/or 8870 thermostats connected to Aprilaire 8811 protocol adapter(s), with or without 8819 and/or 8818 distribution panels.

  • Supports the new thermostatV2 features available with OS 2.7 or later, including Humidity, Humidifier functions, Presets and Schedule.
  • Ability to fully support a mix of 8800 and 8870 thermostats on the same serial port.

  • Supports all 8081 and 8082 Aprilaire remote sensor modules as well as onboard temperature and humidity sensors, including remote temperature sensors connected to 8800 thermostats.

  • Supports all 8061 and 8062 Aprilaire remote sensor modules connected to 8870 thermostats.

  • Can display the temperature of any thermostat or remote sensor on the Navigator interface for any room in the project.

  • Supports schedules, hold modes and vacation mode for 8800 thermostats.

  • Regularly broadcasts time and date to all thermostats.

  • Captures and broadcasts Outdoor temperature to 8800 thermostats.

  • Optionally monitors and forces FAN ON for 8870 thermostats (this thermostat setting is often lost during power outages).

  • Provides reporting of relative humidity though variables available in programming and simulated rH display in some circumstances.

  • Provides a comprehensive set of thermostat commands available in programming.

  • Provides programming commands and variables to manage the 8800 and 8870 as humidistats.

  • Includes the Domosapiens Inter-Devices Facility (DIDF) to allow other drivers to monitor and control individual thermostats through this driver (see detailed section in the documentation)

Additional Improvements over the Aprilaire Legacy Serial Drivers

  • A single set of drivers to support both 8800 and 8870 systems (although there are two versions of the thermostat driver itself).

  • A DriverWorks-based driver set for the 8870 thermostats, allowing for future adaptation and support if required.

  • Enhanced thermostat support, including presets and scheduling, through new thermostatV2 companion drivers compatible with OS 2.7 or later.  The previous drivers remain available for pre-2.7 systems.
  • Ability to broadcast a thermostat's presets and/or schedule to all other thermostats.
  • Automatic detection of the installation’s scale (Fahrenheit or Celsius) and adjustment of the Navigator interface accordingly.

  • Advanced functions to ensure integrity of the project Aprilaire thermostat and modules configuration.

  • An action to print the topology of the Aprilaire network as defined in the project.

  • Support for Emergency Heat mode in programming.

  • A property (Control Scope) to identify thermostats via a message display.

  • 8800 programmable mode (schedules) may be enabled or disabled by the user through the Navigator interface or from the thermostat install menu.

  • New programming variables available to report current thermostat (8800) or remote sensor (8062 or 8082) humidity levels.

  • Ability to send any Aprilaire command to the thermostat from the thermostat driver itself.

  • Ability to display and clear permanent or temporary messages on any or all thermostats.

  • Action (“Print Status Report”) with significant operational information to simplify reporting of issues.
