Heat Mode—Ready vs. Rest
In order for the swim spa to heat, a pump needs to circulate water through the heater(s).
The pump that performs this function is known as the “heater pump”.
The heater pump can be either a 2-speed pump (Pump 1) or a circulation pump.
If the heater pump is a 2-Speed pump 1, Ready Mode will circulate water every 1/2 hour,
using Pump 1 Low, in order to maintain a constant water temperature, heat is needed, and
refresh the temperature display. This is known as “polling”.
Rest Mode will only allow heating during programmed lter cycles. Since polling does not
occur, the temperature display may not show a current temperature 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 o.
Circulation Mode
If the swim spa is congured for 24HR circulation, the heater pump generally runs continu-
ously. Since the heater pump is always running, the swim spa will maintain set temperature
and heat as needed in Ready Mode, without polling.
In Rest Mode, the swim spa will only heat to set temperature during programmed lter
times, even though the water is being ltered constantly when in 24HR circulation mode.
Ready-in-Rest Mode
Ready in Rest Mode appears in the display if the swim spa is in Rest Mode and the Jets 1
Button is pressed. When the heater pump has come on automatically (for example for heat-
ing) you can switch between low speed and high speed but cannot turn the heater pump
o. After 1 hour, the System will revert to Rest Mode. This mode can also be reset by select-
ing the Heat Mode line on the Screen shown on the previous page.
