Abstract

An override control system for an automatic sprinkler system of the type having a control box with a timer for turning on and off at least one sprinkler valve, each sprinkler valve having a valve line which connects to a common line. The override control system includes a probe assembly, having a probe support, a probe having spaced apart electrically conductive members supported by the probe support, and a removable reservoir connectable to the probe support for containing the probe for above ground support while the probe assembly is being used above the ground. The reservoir is removable so that the electrically conductive members are in direct contact with ground dirt when the reservoir is removed and the members are positioned beneath the ground. An electrical circuit is positioned between each valve line and the common line. The electrical circuit includes a relay system so that if moisture between the electrically conductive members is above a predetermined threshold the relay system of the electrical circuit will be activated inhibiting sprinkler operation. If moisture between the electrically conductive members is below the predetermined threshold, the relay system will not energize, thereby allowing said sprinkler system to operate normally.
