The AutoPilot Pool Pilot Digital DIG-220 features an optional internal pump relay that allows the controller to act as your pool's digital time clock. This eliminates the need for a separate external timer and synchronizes your chlorine production perfectly with your pump's runtime.
How the Relay Works with Your Pump
The relay behaves differently depending on the type of pump you have installed:
-
Single-Speed Pumps: The DIG-220 can be programmed for 1 or 2 cycles per day. For example, you can set a single 12-hour block (7 am–7 pm) or two separate blocks (7 am–12 pm and 3 pm–10 pm).
-
Two-Speed Pumps: The controller toggles between High and Low speeds. When the timer signals "On," the pump runs on high; when it signals "Off," the pump drops to low speed. In this configuration, the pump never completely powers down.
-
Variable Speed Pumps: Since VS pumps have their own integrated computers, they require constant power. The AutoPilot relay is not compatible and not necessary for these models. Some customers do choose to use this feature with variable speed pumps however we advise against it as the variable speed pump should be directly wired from the breaker and rely on its own controls.
Step-by-Step: Programming the Relay
By factory default, the DIG-220 is set to "External Timer." Follow these steps to "tell" the controller it is now in charge of your pump:
-
Enter the Installer Menu: Press MENU, scroll to INSTALLER MENU, then PRESS AND HOLD SELECT for 15 seconds.
-
Configure Pump Type: Scroll to PUMP CONTROL. Change the setting from "External Timer" to either One-Speed or Two-Speed. Press SELECT to save.
-
Set Your Schedule: Scroll to PUMP PROGRAM 1. Follow the prompts to set your On and Off times. You can optionally set a second cycle in PUMP PROGRAM 2.
-
Sync the Clock: Go to SET TIME OF DAY and ensure the internal clock matches your current local time.
-
Exit: Scroll to EXIT MENU and press SELECT.
