THE SETTINGS SCREEN
Heat Mode – Ready vs. Rest
In order for the spa to heat, a pump needs to circulate
water through the heater. The pump that performs this
function is known as the “heater pump.”
The heater pump is a 2-Speed Pump 1, Ready Mode and
will circulate water every 1/2 hour, using Pump 1 in Low,
to maintain a constant water temperature, heat as need-
ed, and refresh the temperature display. This is known as
“polling.”
Rest Mode will only allow heating during programmed filter
cycles. Since polling does not occur, the temperature display may not show a current tem-
perature until the heater pump has been running for a minute or two.
When the heater pump has come on automatically (for example for heating) you can switch
between low speed and high speed but you cannot turn the heater pump off.
Circulation Mode
(See Pumps, for other circulation modes)
If the spa is configured for 24HR circulation, the heater pump generally runs continuously.
Since the heater pump is always running, the spa will maintain set temperature and heat as
needed in Ready Mode, without polling.
In Rest Mode, the spa will only heat to set temperature during programmed filter times, even
though the water is being filtered constantly when in 24HR circulation mode.
Ready-in-Rest Mode
Ready-in-Rest Mode appears in the display if the spa is in Rest Mode and the Jets 1 Button
is pressed. When the heater pump has come on automatically (for example for heating) you
can switch between low speed and high speed but you cannot turn the heater pump off. After
1 hour, the System will revert to Rest Mode. This mode can also be reset by selecting the Heat
Mode line on the Screen shown here.
