38ºF (3ºC) is default. This threshold will be used for all outputs that have freeze protection enabled.

When enabled, the filter pump will be forced off when the external input is active. Note that freeze

If the heater is "Enabled", the heater relay will turn on when the water temperature is less than the desired
temperature setting and the filter pump is running. The desired temperature is in the "Settings Menu". If
applicable, the homeowner will be prompted to enter separate "pool" and "spa" settings. Depending on
the position of the pool/spa suction valves, the proper temperature setting will be used.
Heater Cooldown
This feature ensures that the heater cools down before water circulation is stopped. When enabled, the
Aqua Plus will continue to run the filter pump for 5 minutes after the heater turns off. During this period the
filter pump LED will flash and also a "Heater Cooldown, X:XX remaining" message will scroll on the
display.
When the filter pump is running and the heater is on: Pressing the "Filter" button once will cause the
heater to turn off, but the filter pump will continue to run for heater cooldown (filter LED flashing and
message on display). Pushing the filter button a second time will override the heater cooldown operation
and turn the filter pump off.
Heater Extend
If "Enabled", the filter extend logic keeps the filter pump running beyond the normal turn-off time until the
pool (or spa) is heated up to the desired temperature setting (see Settings Menu). Heater extend will NOT
cause the filter pump to turn on, it will only delay the turn off time when the heater is operating.
Allow Low Speed
This menu only appears if the filter is configured for 2-speed operation. During default operation, high
speed mode is used whenever the heater is on. If Allow Low Speed is enabled, low speed will be allowed
even if the heater is on.
Minimum Speed
This menu only appears if the filter is configured for variable speed operation. This is the minimum speed
the pump will run at when the heater is on. The selection is from Filter Lowest to Filter Highest speed.
