A control system is provided having a flow valve, a control valve for controlling flow through the flow valve, a logic circuit for receiving, processing, and transmitting data signals; a central control unit for receiving, processing, and transmitting data signals; and a flow valve actuator. When the flow valve actuator is actuated, the central control unit informs the logic circuit to permit the control valve to allow flow through the flow valve. However, if during a set time period, the flow valve actuator is actuated too often, subsequent actuation is disallowed for a second time period. Also, if during a shut down, subsequent actuation is disallowed. During the second time period or the shut down, any successive actuation is recorded by the central control unit.

The control system of claim 12, wherein the flow valve actuator is a touch sensor. 15. The control system of claim 1, wherein the central control unit further comprises a control module which allows a user to set the first predetermined time period, the second time period, and/or the predetermined allowable activation quantity. 16. The control system of claim 1, wherein the central control unit prevents activation of the control valve upon an input to start a shut down regardless of whether activation of the control valve would exceed the predetermined allowable activation quantity, continues to prevent activation of the control valve until a second input is received to end the shut down or a shut down time period expires, and records any request for activation of the control valve received from the flow valve actuator during the shut down. 17. The control system of claim 16, further comprising a control module which allows a user to send the input to start the shut down, to send the secon d input to end the shut down, or to set the shut down time period. 18. A control system for a fluid piping system, comprising:at least one flow valve having a flow valve fluid inlet and a flow valve fluid outlet;a control valve in fluid communication with the flow valve and configured to control the flow of fluid through the fluid piping system through the flow valve fluid inlet and out the flow valve fluid outlet;a logic circuit in communication with the control valve and configured to receive, process, and transmit data signals through a communication line;a central control unit configured to receive, process, and transmit data signals through the communication line; anda flow valve actuator in communication with the flow valve via the logic circuit and the control valve;wherein, when the flow valve actuator is actuated, an activate data signal is communicated to the central control unit, which communicates an allow data signal to the logic circuit, thereby permitting the logic circuit to communicate an allow to activate data signal to the control valve, allowing the control valve to permit fluid flow from the fluid piping system, through the flow valve fluid inlet and out the flow valve fluid outlet;wherein, if during a first predetermined time period, the flow valve actuator is actuated more than a predetermined allowable activation quantity, the activate data signal is communicated to the central control unit, which communicates a disallow data signal to the logic circuit, thereby not permitting the logic circuit to communicate the allow to activate data signal to the control valve, thereby preventing the control valve to permit fluid to flow through the flow valve, the central control unit continuing to communicate the disallow data signal to the logic circuit for any successive flow valve actuator actuations during a second time period; andwherein, any successive flow valve actuator actuation during the second time period is recorded by the central control unit. 19.
