Relay or Control Outputs, Intermittent Sampling Control Mode
ONLY AVAILABLE IF HVAC MODES ARE ENABLED IN CONFIG MENU – GLOBAL SETTINGS

a timed schedule, and the relay responds to maintain the conductivity value at the set point by activating for a
programmable amount of time that varies with the deviation from the set point.
