If the hot tub water is more than 20°F cooler than the
temperature setpoint, jets pump #1 and heater will
automatically activate to provide freeze protection. The
hot tub will stay in this mode until the water
temperature reaches 15 degrees below the set
temperature then turns off. No corrective action is
necessary.

water is inhibited or a ow switch has malfunctioned.
Check for proper water level and for clogged lter
(pages 42-43). Contact your Sundance Spas dealer or
qualied service technician.
*Note: This message can also appear if the pump has
not regained prime after the hot tub has been drained
and relled. If you suspect that this is the case, see the
instructions on page 52 under “pump does not
operate and icon does.”
Circuit board temperature has exceeded acceptable
limit. This message will disappear when the circuit
board temperature drops below acceptable limit. If

when the hot tub is rst lled because tap water is
often very cold.

or remote control panel and circuit board is faulty.
Contact your Sundance Spas dealer or qualied
