Abstract
This disclosure relates to a fresh air ventilation (FAV) controller. The FAV controller may include multiple input devices for setting a target fresh air ventilation flow rate (FAVFR), an operating FAVFR for an air handler, an operating FAVFR of a first ventilation appliance, an operating FAVFR of a second ventilation appliance. The FAV controller further includes electric interfaces adapted to couple to the air handler and a thermostat for controlling the air handler, a sensor for monitoring an operation of the first ventilation appliance, the second ventilation appliance, a thermometer for monitoring temperature of fresh air in a ventilation path to the air handler, and a motorized damper disposed in the fresh air ventilation path. The FAV controller may be configured to monitor operation times of the air handler, the first ventilation appliance, the second ventilation appliance, and the thermometer via the electric interfaces, and to control the air handler and the motorized damper, and/or the second ventilation appliance via the electric interfaces.
