Systems with higher GPM ratings will require a bypass around Heater or
2 way valve to reduce water fl ow if required. This would be necessary if
a high velocity pump is employed in the system.
Add water softener for longer heater life.

“PSI” (Pressure Switch)
LOW or NO water pressure is detected; “PSI” needs to be
adjusted by turning small wheel on Pressure Switch up or
down. Up = increases water pressure; Down = decreases
water pressure.
“LO”
Low water temperature is detected; meaning that the
temperature is below the range of the thermostat. Heater is
still running. Follow point 3 instructions to correct this error
code.
“HI” (HAUT) + “LOC”
High water temperature is detected; meaning that the water
temperature goes above the range of the thermostat (see point
3 for highest temperature setting). The Heater will turn OFF
for safety. The display will show “HI “until the temperature
decreases to the original programmed temperature setting
(customer’s setting).
As a built-in safety feature, the heater will automatically go into
“lock” mode, once the programmed temperature has been
reached. This is to avoid any manual temperature adjustments
at that time.
The display will now show “LOC” and the heater is turned
OFF.
The thermostat will remain in this condition (OFF) even if
power is turned off and on again.
To clear the lock (LOC) condition, press the UP or DOWN
button (to decrease or increase desired temperature) .
Notes:
Heater will show “OFF” on display, if temperature is below
the lowest set point (70 degree. F / 20 degree. C). Therefore
the heater is in the off-position. Start to follow point 3 for Pool
or Spa application to turn heater on and to set it to desired
temperature.
