TOPSIDE PANEL DISPLAY MESSAGES
OHH/HTR TEMP LMT/OH/HL (solid or flashing)
Overheat – Spa has shut down. One of the sensors
has detected 48°C (119°F) at the heater.
DO NOT ENTER WATER! Remove cover and allow
water to cool. Reset system by pressing any
topside control panel pad. If system does not reset,
shut off power and call your dealer.
POSSIBLE CAUSES OF OVERHEATING
 filter cycle too long or overlapping (pump
running for extended periods of me)
• isolaon/gate valves parally closed
 extremely hot weather/high ambient
temperatures
• defecve sensor wire
ICE/FREEZE COND
Potenal freeze condion detected. Pumps and
blower will automacally acvate when
temperature drops to 4°C (39°F) regardless of
operaon mode.
SnA/SENSOR A SERVICE RQD
Spa has shut down – sensor plugged into Sensor
‘A’ port not working.
SnB/SENSOR B SERVICE RQD
Spa has shut down – sensor plugged into Sensor
‘B’ port notworking.
SnS/SENSOR SYNC
Sensors are out of balance – If topside display
alternates between temperature and SNS, then
occurrence may be temporary and will correct
itself. The spa shuts down completely when the
SNS message is flashing on the display.
HFL/HTR FLOW LOW
A substanal difference in temperature between
the sensors has been detected – this could
indicate a flow problem. Check water level in spa
and add if necessary, also ensure the filter is
clean. If water level is okay, make sure that pumps
are primed and all gate valves are fully opened.
LF/LOW FLOW
Persistent low flow problem – displays on the fih
occurrence of an HFL message within a 24 hour
period. Heater circuit is deacvated but other spa
funcons connue to operate normally. Check
water level in spa and add if necessary, also
ensure the filter is clean. If water level is okay,
make sure that pumps are primed and all gate
valves are fully opened. Press any topside panel
pad to reset.
