Pump & 3-Way Valve Blockage Protection Function
Blockage protection protects the pump against possible blockage if the pump does not operate for a
long time, this function protects the pump against blockage by operating the pump for 5 seconds every
24 hours, as long as your device is connected to the electrical circuit. The same applies to 3-way valves,
as long as your appliance is connected to the electrical circuit, 3-way valve protection protects against
blockage by providing directional change if the 3-way valve has not changed direction in the last 24
hours.
