Priotomo Abiprojo

A circulator blower controller for a circulator blower of a heating, ventilation, and air conditioning (HVAC) system of a building includes an interface configured to receive a demand signal with an operating mode from a thermostat. A switching circuit selectively connects power to a tap of a motor of the circulator blower. A data store configured to store a mapping from a speed to the tap. For each tap, a processor observes power consumed by the circulator blower while power is connected to the tap by the switching circuit. The processor determines the mapping by sorting the taps based on observed power consumption. The processor selects a first speed based on the demand signal from the thermostat. The processor identifies a first tap from the mapping based on the first speed and generates the tap selection signal to control the switching circuit to connect power to the first tap.

Adaptive control for motor fan with multiple speed taps

A system and method for monitoring a heating, ventilation, or air conditioning (HVAC) system of a building is provided. A monitoring server, located remotely from the building, is configured to receive power consumption data and control signal data from a monitoring device at the building and to receive energy pricing data from a customer device associated with the HVAC system or a database that stores energy pricing data. The monitoring server is configured to determine energy cost data for segments of a selected time period based on the power consumption data, the control signal data, and the energy pricing data. The monitoring server is also configured to communicate the energy cost data to the customer device for display on the customer device.
