First Claim
1. A kit for a heating, ventilating, air conditioning and humidifying system that includes heating means, ventilating means, air conditioning means and humidifying means in a plant area comprising:
- a remote control unit located remotely from said plant area and including;
a temperature control means for controlling the operation of said heating and air conditioning means,a ventilating control means for controlling the operation of said ventilating means, anda humidity control means for controlling the operation of said humidifying means independent of said ventilating control means;
a main control unit located adjacent said plant area and including;
heat responsive means responsive to said temperature control means for activating said heating means,cool responsive means responsive to said temperature control means for activating said air conditioning means,ventilating responsive means responsive to at least said ventilating control means for activating said ventilating means, andhumidity responsive means responsive to said humidity control means for activating said humidifying means;
a connecting link means for coupling said remote control unit to said main control unit consisting essentially of first, second, third and fourth wires extending from said main control unit to said remote control unit, said first wire coupling AC potential to said remote control unit, said second wire coupling said temperature control means to said main control unit, said third wire coupling said ventilating control means to said main control unit and said fourth wire coupling said humidity control means to said main control unit; and
connecting means extending from said main control unit to said plant area to thereby have said heat, cool, ventilating and humidity responsive means control the operation of said heating means, said ventilating means, said air conditioning means and said humidifying means in said plant area.

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.
