When activated, the Fogger Single Cycle Controller starts fogger operation immediately and runs for a predetermined period of time — up to 2.84 hours — then switches off. The run time is set by selecting toggle switches that total the number of seconds of desired application time. The total air CFM requirement of all the foggers connected to this controller must be less than 460 CFM, which is the air CFM capacity of the controller's 3/4 inch solenoid. (For a lower air capacity requirement of 180 CFM and below, see controller model #950800.)
