"How Does It Work?"
System checks for DC power relay (master control relay) activity. Code dCP
is displayed if error is found. Usually the board must
be replaced. Could be low current to spa or transformer problems.
Water Temp-Hts-Water Temp,
tS-0-ts, or tS-255-Ht-Oht-tS-
System checks the integrity of the water temperature sensor. If the
temperature sensor has failed, one of these errors will show on the topside.
Usually needs a new temp sensor. Sometimes the board
itself has failed.
System checks for water
flow through the circulation/filtration and heater plumbing. During this
process, the system checks to see if the circulation pump has input current. If
an error is detected, the topside control displays the code
Heater is deactivated. Filter pump may have lost prime and is overheating
and stopped running or the filter pump cord is disconnected. Automatic reset
will occur if this condition is fixed faster than ~ 5 minutes. Manual reset is
requested if this condition has been in place more than 5 minutes. Check for
proper water level, pump is primed, leaks and/or clogged filter. Check for
filter pump cord connection. Usually means circ pump has
System checks the
pressure switch for switch open with the circulation pump off. System checks
automatically for this condition every 96 hours. If the error is detected, the
topside control displays the code PS2-Water
Temp-PS2. Heater and
circulation pump are deactivated. Automatic reset will occur if this condition
is fixed. Pressure switch may need to be adjusted or
replaced or water level is too high.
System checks the
pressure switch for switch closure with circulation pump on. If an error is
detected the topside control displays PS1-Water
Temp-PS1-. The heater is deactivated.
Automatic reset will occur if this condition is fixed in less than ~ 5minutes.
Manual reset is required if this condition continues for more than 5 minutes.
Try removing the filters and restarting system. If PS1
discontinues, replace filters. If you do not see water movement, circulation
pump likely failed. Replaced. If you see water movement and filters are out but
PS1 is still present, replace pressure switch.
Freeze condition. System
checks the water temperature for a reading at or below 60deg F. If below, the
topside control displays the code FC-Water Temp-FC-.
A potential freeze condition has been detected (60 deg F or below). No
action required. The system will automatically energize the heater. The heater
will be energized even in the ECO mode. The spa will automatically bring the
water temperature up until the spa is out of danger. When the water
temperature in the spa is equal to or less than 50 deg F both pump relays are
energized for 5 minutes (heater is deactivated during this time), heater is
energized for 20 minutes again (pumps are deactivated during this time) and this
cycle is repeated until the water temperature is equal to or above 60 deg F.
High temperature condition. System checks for
the spa water temperature equal to or above 110deg F. If a water temperature
equal to or above 110deg F is detected, the topside control LED readout flashes
between the spa water temperature and
Ht. The Air Blower (if equipped) is
automatically energized to assist in lowering water temperature. The blower will
be deactivated after the spa water temperature drops below 107deg F. This case
may be due to excessive single speed pump(s) operation, i.e. resetting the
Jets1, Jets2 (if equipped) continuously after each 20 minute shut down cycle
until the spa water reaches this temperature. Allow time for the system to reset
the spa. If Ht returns and topside temp is correct,
usually means board must be replaced.
condition/watchdog. System checks for the spa water temperature equal to
or above 120deg F or the heater enclosure temperature is equal to or above
125deg F. If either the spa water temperature is equal to or above 120deg F or
the heater enclosure temperature is equal to or above 125deg F, the topside
control display flashes Oht-Water Temp-Oht
and the entire system is disabled. Oht condition requires
Manual Reset action either by pushing the WARMER and COOLER buttons
simultaneously, or by turning the main power off and then back on. The heater or
water high limit switch cannot be reset until the heater enclosure temperature
drops below 123deg F or water temperature in the spa drops below 117deg F. If actual water temp is same as topside, likely must
