Abstract: A Heating, Ventilating Air Conditioning (HVAC) fan control method to detect an HVAC fan is controlled by at least one fan-on duration control selected by a user and provide at least one fan-on alarm message prior to overriding the at least one fan-on duration control. The method monitors an occupancy sensor signal to determine an occupancy in a conditioned space served by an HVAC system and automatically overrides the at least one fan-on duration control to save energy when the conditioned space is unoccupied. The overriding may comprise operating the HVAC fan based only on a thermostat call for cooling or a thermostat call for heating, operating the HVAC fan for less time than the at least one fan-on duration control selected by the user, and operating the HVAC fan for less frequency than the at least one fan-on duration control selected by the user.

The sealing material is selected from the group consisting of: an adhesive tape sealant, an adhesive sealant, a mastic sealant, a caulking material, and a weatherstripping. The method comprises: disconnecting an electrical power to the HVAC system, removing an economizer hood, locating and cleaning the metal services on both sides of the gap between the economizer frame and the HVAC cabinet, applying the sealing material over or into the gap, reinstalling the economizer hood, and reconnecting the electrical power to the HVAC system.

Abstract: A method for controlling a Heating, Ventilation, Air Conditioning (HVAC) fan based on at least one Fault Detection Diagnostic (FDD) output wherein a previously monitored HVAC parameter is compared to a current HVAC parameter, and if a fault is detected, and impacts energy efficiency performance, then the FDD output is used to perform at least one action selected from the group consisting of: turning off a fan accidentally left on, and determining and providing a variable fan-off delay at the end of a heating or cooling cycle to improve energy efficiency, where both actions are based on HVAC parameters including, for example: a heating cycle duration, a cooling cycle duration, a conditioned space temperature and the rate of change of the HVAC parameters with respect to time. The method may be embodied in a fan controller, forced air unit control board, thermostat, or fan motor.

Abstract: A solid-state common-wire adapter combines two Heating, Ventilating, Air Conditioning (HVAC) control signals on a single pre-existing wire to allow another pre-existing wire to be used as a common-wire to provide reliable power to a Smart Communicating Thermostat. The solid-state common-wire adapter may comprise a thermostat element with at least one diode and an HVAC element with at least one device selected from the group consisting of: a solid-state TRIode for Alternating Current (TRIAC), a capacitor, a microprocessor, a power supply, an optoisolator, and a load resistor. Smart Communicating Thermostats require continuous power for communicating with a wireless network, providing a Liquid Crystal Display (LCD) display, and controlling an HVAC system. Some Smart Communicating Thermostats use power stealing which is unreliable. The solid-state common-wire adapter is reliable, small, low-cost, and easy to install.

Abstract: A method for controlling heater ventilation fan operation increases fan speed from low to high after a short delay after turn-on, and continues fan operation for a period of time based on duration of operation, after turn-off. The higher fan speed improves heat transfer and efficiency while the heating system is operating. Continuing fan operation after turn-off maximizes recovery of additional heat from the heat exchanger. Known methods do not provide sufficient air flow to efficiently transfer heat from the heat exchanger to the air, and leave high temperature air (i.e., 110 to 200° F.) in the heat exchanger after turn-off.

Abstract: An efficient fan controller for Heating Ventilating Air Conditioning (HVAC) systems including at least one electrical signal input from thermostat or equipment control terminals with a microprocessor to control a switching device connected to a signal output to control a fan relay and operate a system fan. The microprocessor is configured to monitor a thermostat call for cooling/heating duration and determine a variable fan-off delay based on the cooling cycle or heating cycle duration, and at an end of a cooling/heating cycle energize the fan relay to operate the system fan for the variable fan-off delay. The fan controller can include a heat pump detection signal input and electrical signal inputs to connect to a thermostat heat terminal, heat pump reversing valve terminal, or compressor terminal. The fan controller can also include a normally-closed relay connected to the switching device to maintain continuity between the fan signal input and output.

Abstract: Apparatus and methods are disclosed for a fan controller. The fan controller determines HVAC system type and heating or cooling mode for gas furnace, heat pump, electric resistance, and hydronic heating, ventilating, and air conditioning (HVAC) systems. For gas furnace heating systems, the apparatus and methods include energizing the blower fan from a lower fan speed used for heating by the furnace-fan controller to the high-speed used for cooling by the fan controller after fan-on delay time P1 to increase delivered heating capacity, satisfy the thermostat sooner and save heating energy. For heat pump, electric resistance, and hydronic heating systems the apparatus and methods include energizing the fan relay after a short fan-on delay time P0 based on previous off-cycle duration P11. For all these HVAC systems, the apparatus and methods vary extended fan-off time delay P2 as a function of cool-source operational time P4 or heat-source operational time P3.

Abstract: A method for efficient control of a heater ventilation fan. The method includes switching the heater ventilation fan from low speed to high speed after a brief period P1 following starting, and continuing heater ventilation fan operation for a variable period of time P2 after the heat source has stopped. The period P1 is preferably about four minutes, and the period P2 is determined by the duration of heating and is generally between two and four minutes. Operating the heater ventilation fan at high speed improves heat transfer and efficiency while the heating system is operating, increases warm air movement to the space, satisfies the thermostat set point temperature in less time, reduces heating system operation, and reduces energy use. Continuing heater ventilation fan operation after turn-off maximizes recovery of additional heat from the heat exchanger to improve overall efficiency, extend the off cycle time, and save energy.

Abstract translation: 一种有效控制加热器通风扇的方法。 该方法包括在启动后的短暂时间段P1之后将加热器通风扇从低速切换到高速，并且在热源停止之后持续加热器通风扇在可变时间段P2内运行。 期间P1优选为约4分钟，期间P2由加热持续时间确定，通常为2至4分钟。 在加热系统运行时，加热加热器风扇高速运转，提高了传热效率，增加了暖空气的运动，在较短的时间内满足了恒温器的设定点温度，减少了加热系统的运行，减少了能源消耗。 关闭后继续进行加热器通风风扇的操作可最大限度地提高热交换器的附加热量的回收率，从而提高总体效率，延长关闭循环时间，节约能源。
