CS7500/CS6500 - ERROR MESSAGES
PRESSURE or FLOW SWITCH ACTIVATED
- This error is an indication the pressure or flow
switch is not opening when the pump is off, the programming is not correct, or low level
programming has just been done with the pump running.
Confirm proper system programming and/or pressure switch calibration
Contact your local spa dealer
PRESSURE or FLOW SWITCH NOT ACTIVATED
- This error is an indication the pressure or
flow switch is not closing when the pump is on. Check for dirty filter, proper water level and
flow, if the error does not clear this is an indication that the pressure or flow switch may need to
be adjusted or replaced.
Contact your local spa dealer
TEMPERATURE SENSOR MALFUNCTION
- This error will occur when a problem with the
temperature sensor exists. This error may also occur if the system is activated while the water
temperature is below 35°F.
Contact your local spa dealer
OVERHEAT or HIGH-LIMIT PROTECTION
- There are three (3) stages of over-temperture:
1 - The spa water has exceeded 112°F. The heater, pump and accessory will be deactivated
until the water cools to 109°F.
Be sure to check the actual water temperature with an accurate
thermometer.
2 - The spa water has exceeded 119°F. The heater will deactivate while the pump and
accessory will still operate. The blower (if equipped) can be activated to help cool the water.
WATER MUST BE BELOW 119°F AND POWER MUST BE RESET TO CLEAR THE “HL”
ERROR
A dirty spa filter can also cause a restricted flow of water, be sure the filter is cleaned regularly
and ensure all water shutoff valves are open.
If the system has been operating normally until now, the pump may be overheating the spa.
Refer to “Programing Filtration” on page X and reduce the duration and/or number of cycles per
day.
3 - If you’ve eliminated items 1 & 2 as problems, the high-limit sensor may have malfunctioned.
Contact your local spa dealer
FREEZE PROTECTION:
SMART WINTER MODE:
This mode will activate any time the ambient/outside temperature falls below
59°F if required. This mode will be active for a period of 24-hours. In this mode, if a pump has not
been activated in the last 2 hours, the system will automatically turn it on for 1-minute every 2 hours to
prevent freezing. The “Filter Cycle” indicator will flash while this mode is active.
