APOLLO Pool Flow Switch

APOLLO Pool Flow Switch

Proves whether liquid is moving in the pipe. The setpoint is adjusted on the unit, and six LEDs show where the flow sits relative to that point. The relay provides normally open and normally closed contacts.

The LEDs are one red, one yellow, and four green. Red means the flow is below the setpoint: the normally closed contact is closed and the normally open contact is open. Yellow means the flow is at or above the setpoint: the normally closed contact opens and the normally open contact closes. Above the setpoint, one to four green LEDs show how far the flow is above it, in steps of about 20% of the full-pipe flow.

Power is 24 V DC on pins 1 and 3. The five wires are 1 brown, 2 white, 3 blue, 4 black, and 5 grey. Normally closed is pins 2 and 5. Normally open is pins 4 and 5.

The setpoint is an internal potentiometer under a sealing screw. Turn it clockwise to raise the setpoint. During setup, run normal flow for 3–5 minutes before adjusting, then wait 1–3 minutes for the switch to store the setting.
