Abstract: Systems, methods, and circuitries are provided for a controller for a fuel oil burner system that controls a fuel oil burner to perform intermittent ON cycles. In one example, a controller includes a memory configured to store a value for one or more burner control delay periods and a processor. The processor is configured to perform an auto-set procedure in a first ON cycle. The auto-set procedure includes detecting an oil valve in the fuel oil burner; determining that the value for a burner control delay period is a default value; and in response, storing a valve-present value as the value for the burner control delay period in the memory.

Abstract: Methods, systems, and circuitries are provided for detecting flame in a fuel oil burner. In one example, a method includes receiving a series of one or more light samples, each indicative of a level of light. When the fuel oil burner is operating in the flame expected mode, the method includes determining whether the values of the one or more of the light samples exceed a flame threshold; determining whether the values of the one or more of the light samples meet secondary criteria; determining that a flame is present when the values of the one or more light samples exceed the flame threshold and meet the secondary criteria; and determining that a flame is not present when the values of the one or more light samples are below the flame threshold or do not meet the secondary criteria.

Abstract: A tank adapter has a body with first and second ends and an axial hole. A hollow cylinder of the body has an external tapered thread from the first end toward the second end of the body. A flange between the first and second ends has a flat face extending radially outward from the hollow cylinder to a flange outer diameter. A gage mount portion has a gage mount outer diameter that is less than the flange outer diameter and extends from the second end toward the first end and has gage mounting features for securing a level gage. A gasket mates with the flat face. In a first configuration, the external tapered thread engages an internal tapered thread of a first tank opening. In a second configuration, a collar nut compresses the gasket between the flange and a top rim of a second tank opening.

Abstract: Some aspects of the present disclosure relate to a sensor probe kit that has an electrical connection that ensures a sensor probe has been properly positioned in a boiler well. In some embodiments, the sensor probe kit has a seating mechanism that positively positions a sensor probe at a predetermined position within a boiler well. In many instances, the seating mechanism provides tactile feedback to an installer when the sensor probe is properly positioned within the boiler well. These features can help ensure the sensor probe is properly installed, and helps keep the sensor probe electrically connected to the well at all times after installation.

Abstract: One embodiment relates to a method for temperature regulation of a medium to be circulated through a plurality of zones of a facility. In this method, a call for heat is received. The method identifies a zone within the plurality of zones from which the call for heat originated. The medium is then heated to a first temperature range if the identified zone is a first zone within the facility and is heated to a second temperature range if the identified zone is a second zone within the facility. The first and second temperature ranges differ from one another. Other methods and systems are also disclosed.

Abstract: Some embodiments of the present disclosure relate to a mobile battery module for high power applications. The mobile battery module includes a case having a chamber therein, wherein one or more engagement elements are disposed on an inner surface of the case. A number of blocks removably engage the one or more engagement elements, wherein each block includes a pair of opposing sidewalls. Within each block, a number of end caps extend from the opposing sidewalls to cooperatively hold a number of respective cells there between.

Abstract: The present disclosure relates to an apparatus for automatically shutting down a boiler system when it is not needed (e.g., during warm weather) based upon calls for heat output by a temperature control element (e.g., thermostat) within a facility. The apparatus has a temperature control element that provides calls for heat to a controller when a temperature within a facility is below a setting value. The controller controls operation of a boiler, having a medium with a temperature between a low limit and a high limit, in response to the call for heat. A monitoring element determines a prevalence of calls for heat and selectively adjusts the low limit based upon the determined prevalence of calls for heat. Therefore, when calls for heat are less frequent the monitoring element will reduce the low limit to reduce fuel consumption of the boiler.

Abstract: A system and method is presented for a multi-sensor component for an HVAC system. The multi-sensor component comprises a sensor assembly, having a temperature detector for measuring a temperature of an object or medium, a presence detector to detect the presence of the object or medium against the sensor, and a pressure detector for measuring a pressure of the medium. The temperature, presence and pressure detectors may also be affixed within a single sensor housing. In a heating mode the multi-sensor component is heated by a heater, and in a cooling mode the multi-sensor component cools toward a temperature of the object or medium, and the temperature detector provides temperature data indicative of a temperature response comprising one of a temperature change, a rate of change and a time constant of a thermal decay rate of the multi-sensor component and the presence of the object or medium.

Abstract: An economizer component of a controller used for fuel efficient temperature regulation of a medium circulated through a zone within a hydronic and steam heating system is disclosed.

The control signal has an adjustable high limit, and the dynamic adaptation module is configured to increment the adjustable high limit by an increment value, to a value no greater than a maximum high limit, if it is determined that the system requires heat, and decrement the adjustable high limit by a decrement value, to a value no lower than a minimum high limit, if it is determined that the system does not require heat.

A first battery module current limiter is configured to monitor a current flowing to or from the plurality of rechargeable cells of the first battery module. The battery module current limiter is further configured to selectively limit the current flowing to a non-zero current that is less than a predetermined current threshold, wherein the selectively limiting is based on whether the monitored current is approaching the predetermined current threshold.
