Abstract
An actuator having two or more potentiometers for setting an address for use with a communications bus or the like. An adjustment or setting of the potentiometers may be accessible at two or more sides outside of a housing enclosing the actuator. One potentiometer may be set to a direction of control and a range of addresses. Another potentiometer may be set to one of several addresses within a range of addresses and direction of control selected on the first potentiometer.
Claims20
An actuator system for a heating, ventilating and air conditioning (HVAC) setup, comprising:
- an electromechanical mover;
- a processor connected to the electromechanical mover;
- and
- a first potentiometer, having a set of directions of control and a plurality of ranges for addresses, connected to the processor;
- a second potentiometer having a plurality of addresses connected to the processor;
- and
- a housing that encloses the actuator;
- and
- wherein:
- access to the potentiometers for selecting or changing an address for the actuator is available on at least two sides of the housing;
- an address for the actuator comprises:
- a direction of control selected from the set of directions of control on the first potentiometer;
- a range of addresses selected from the plurality of ranges on the first potentiometer;
- and
- an address selected from the plurality of addresses on the second potentiometer within the range of addresses selected from the plurality of ranges for addresses.
A method for establishing an address for an actuator in a heating, ventilating and air conditioning (HVAC) system, comprising:
- providing an address for an HVAC actuator on a communications bus by providing an input to the processor;
- connecting the processor to an electromagnetic mover;
- and
- connecting the electromagnetic mover to an HVAC actuator shaft coupling;
- and
- wherein:
- the input to the processor comprises an address for the HVAC actuator provided by selections made on first and second potentiometers;
- the first and second potentiometers have a plurality of selections for providing inputs to the processor;
- an address for the actuator comprises a selection of a direction of control from the set of directions of control, a range of addresses from the plurality of ranges on the first potentiometer, and an address from the plurality of addresses on the second potentiometer;
- the inputs comprise different addresses for the actuator on the communications bus;
- and
- the actuator shaft coupling can mechanically operate an apparatus in an HVAC system.
An actuator for a heating, ventilating and air conditioning (HVAC) system, comprising:
- an output shaft coupling;
- an electromagnetic mover mechanically connected to the output shaft coupling;
- a processor connected to the electromagnetic mover;
- a first potentiometer, having a set of directions of control and a plurality of ranges for addresses, connected to the processor;
- and
- a second potentiometer having a plurality of addresses, connected to the processor;
- and
- wherein:
- an address for the actuator comprises a selection of a direction of control from the set of directions of control, a range of addresses from the plurality of ranges on the first potentiometer, and an address from the plurality of addresses on the second potentiometer.
