ABSTRACT:
An environmental control system for controlling heating, ventilation, humidification and air conditioning equipment located in plant area of a house includes a kit consisting of a remote control unit located in a living space of a house that is linked by a four wire link to a main control unit located in or adjacent the plant area. The remote control unit has a temperature control device, a humidity control device, and a fan control device. Additionally, the remote control unit may include indicating devices and/or an internal battery charger for a rechargeable battery that may be used to operate electronic circuits and controls in the remote unit. AC power from an AC transformer in the plant area is supplied to each of the control devices via the four wire link. The main control unit has relay coils coupled to the four wires in the wire link via selectively poled diodes. The selective energizing of these relay coils results in the opening and closing of relay contacts in the main control unit through which AC power is supplied to the heating, ventilation, humidification and air conditioning equipment located in the plant area to thereby control the operation of that equipment.
