Heater

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 valve, 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 OnCommand 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 or variable 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.
