Abstract

A programmable electronic controller that provides multiple command and control instruction for an air curtain being integrated therewith. The controller includes operational controls for fan speed, time adjustment duration including time delay, start time, stop time with internal selectable timer clock provisions. The temperature imputable parameters for on demand heat and a variety of remote sensing and actuation output and input provisions.

Claims

1. An integrated programmable electronic controller for air handling equipment comprises in combination, an air curtain apparatus to establish an airflow stream as an effective environmental barrier between temperature divergent environments, and multiple sensor interfaced with air curtain command and control,

said controller having an integrated central microprocessor, a control data input group and a control element group;

a communication network interconnecting said air curtain and respective control data input and control element groups with said central microprocessor,

said control data input group comprising, a first temperature sensor for obtaining an internal temperature value,

a second temperature sensor for obtaining a remote temperature value of said temperature divergent environments,

a fan motor speed sensor for adjusting air velocity of said air curtain,

a threshold motion sensor,

contact threshold sensor and a remote control sensor,

said control element group comprising an air curtain fan motor assembly and air conditioning units, input data control values as functional control messages including a full speed start for said fan motor assemblies and operational time delay for said air curtain controller, means for communication with additional controllers, threshold control mode settings of said control data input group comprising an off setting, an on setting and an auto setting and a clock control for an event based control of said threshold control mode settings, network for transmitting data from said data input group and intercommunication transmission with said control element group and display means.

2. The integrated programmable electronic controller set forth in claim 1 wherein said means for communicating with additional electronic controllers comprise,

serial inputs and output links.
