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 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 as 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 heat-
ing) you can switch between low speed and high speed but you cannot
turn the heater pump off.
CIRCULATION MODE
If the spa is congured 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
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 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.
