The Countdown timer is programmed in increments of 5 minutes from "Manual On/Off" (0 minutes) to a maximum of "21:00" (21 hours). When "Manual On/Off" is displayed, the countdown timer is disabled and the output will be manually controlled. When a countdown timer is equal or greater than "0:05", pressing the appropriate output button will turn the output on and start the timer. Pressing the button again will turn the output off or, when the programmed time has elapsed, the output will automatically turn off.

For pool/spa combination systems with spillover enabled, the valves will automatically switch to spillover mode at the start of the filtration period. For all other systems, the valves will switch to the pool-only position. Refer to the text above for general notes regarding timeclock programming. For two speed or variable speed pumps, this setting will be the period of time when the pump runs at high speed (the word "Filter T1" in the display will be replaced with "Filter Hi"). There is a separate timeclock for the low speed operation (see "Filter T2" below). If the high speed and low speed periods overlap, then the pump will operate in low speed during the overlap period. There are several reasons the filter pump may be running at times other than the timeclock period set above. These include super chlorinate, spa operation, manual operation, heater cooldown, freeze protection and "solar-extend".

If the filter pump was off prior to the start of this time period, the filter pump will first turn on at high speed for 3 minutes to prime and establish water flow. Afterwards, it will drop down to low speed for the remainder of the programmed low speed time period. While this time clock will override the high speed timeclock (see above), there are several reasons why the pump will automatically switch to high speed operation during this programmed time period. These include manual operation, spa operation, or heating operation. Refer to page 11 for general notes regarding timeclock programming. 12 USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
