AUTOMATED FEATURE FUNCTIONS
POWER UP/BOOT UP DISPLAY SEQUENCE
Once power to your Eco Spa has been turned on, each of the following parameters initially
appears in the Topside Controller Display for 2 seconds in this sequence:
AUTOMATIC DRY-FIRE PROTECTION
After the above sequence of parameters has appeared at power up, the Topside Controller’s
Display will show “- - -“ and the pump starts on Low Speed for 2 minutes as the Eco Spa’s
System performs a flow check to verify a proper water flow rate to the heater of 18 GPM to
protect the heater from firing prematurely (“dry fire”). Once proper water flow rate is verified,
the current water temperature will then be shown in the display, toggling with the current
time.
AUTOMATIC WATER TEMPERATURE REGULATION
Every 15 to 90 minutes the pump will come on at Low Speed to ensure accurate water
temperature as well as to avoid heater activation in “dry fire” conditions (inadequate or absent
water flow through the heater element). Over time, the system will “learn’ your spa’s water
temperature variations and thus at what time interval it needs to check and adjust it.
After verifying water flow, pump activation on Low Speed and taking a water temperature
reading, if the water temperature has fallen below the Set Point, the system automatically
turns the heater on to reach and maintain water temperature at Set Point. Once the water
temperature has reached the Set Point value plus 0.8° F the heater is turned off.
The Set Point icon flashes when taking water temperature reading. To override this mode
and immediately turn on the heater simply press the WARM button.
AUTOMATIC HEATER ELEMENT COOLDOWN
If the Heater has been On, the pump will continue to run on Low speed for 2 minutes to cool
the heater element and help prolong its useful life. If the water temperature is below the
desired set point, the pump will stay on Low speed to operate the heater until the desired
temperature set point has been reached, and then run an additional 2 minutes to cool down
the heater element.
