Abstract
An electric heater is provided with an identifying resistor associated with a connection between the heater and a fan control. When the electric heater is connected to the control, the identifying resistor provides information with regard to the capacity of the particular electric heater that is being attached to the control. The control then utilizes this particular capacity to control both the electric heater and an associated fan motor.
Claims13
An electric heater and fan combination comprising:
- an electric heater having any one of several available capacities, and having an identifying characteristic to be automatically reported to a control, said identifying characteristic being associated by said control with said one of said available capacities;
- a fan for delivering air over said electric heater, said fan also being under the control of said control;
- and
- said control receiving said identifying characteristic from said electric heater, and associating said identifying characteristic with said one capacity, and using said one capacity to provide control over said heater and said fan.
A method of providing heated air into an environment comprising the steps of:
- (1) providing an electric heater, and a fan for delivering air over said electric heater, and ten into an environment to be heated, and providing an electronic control to control said electric hearer and said fan;
- (2) connecting said electric heater to said fan, and providing information from said electric heater to said control of a capacity of said electric heater;
- (3) associating said provided information with a capacity of said fan from information previously stored at said control;
- and
- (4) utilizing said control to control said fan based upon said determined capacity.
A heating, ventilating and air conditioning system, comprising:
- a utility device having any one of several available capacities, and having an identifying characteristic to be reported to a control without manual intervention, said identifying characteristic being associated by said control with said one of said available capacities;
- and
- said control receiving said identifying characteristic from said utility device, and associating said identifying characteristic with said one capacity, and using said one capacity to provide control over said utility device.
