Time Setting

NOTE: DO NOT SET THE TIME BY ROTATING “OUTER” DIAL. TO SET THE CURRENT TIME, TURN THE MINUTE HAND CLOCKWISE.

Turn the minute hand clockwise until time of day on the outer dial is aligned with the triangle marker on the inner dial.

Example for 10:30 AM. Turn the minute hand clockwise until 10:30 AM is aligned with the triangle on the inner dial. The hour and the minute dial will show exactly 10:30.

Programming

24-Hour (Timer manual switch position)

The 24-Hour dial has quarter-hour division tabs plus AM/PM indications. Set the required "ON/OFF" times on the programming ring by pushing the tabs away from or towards the center of the ring. Tabs pushed away from the center ring indicate circulator "ON" while tabs pushed towards the center ring indicate circulator is switched "OFF". The circulator will now start/stop according to the settings of the programming tabs.
