6) If the unit is heating water, it won't stop until set point is
reached or heater is stopped.

5 TIME CLOCK

This heater can work aside a time clock. Just set the desired
temperature on the heater and switch it on.
While the pump is idle, so will be the heater. When the
filtration pump starts working the heater will detect it and will
heat the water if needed.
6 TROUBLE SHOOTING
UNIT SCREEN DOES NOT LIGHT UP
CAUSE #1: Power failure external to the heater.
SOLUTION #1: Check and fix power supply.
UNIT WORKS INTERMITENTLY
CAUSE #1: Water flow near minimum value.
SOLUTION #1: Check water flow and increase it if
necessary.
UNIT IS SWITCHED ON BUT IT IS NOT HEATING WATER
CAUSE #1: Check if temperature set point has been reached.
If so, the unit is not heating water since water already has
desired temperature:
CAUSE #2: Check if there is water flow. If water flow is not
detected by the heater, the unit is not allowed to heat water:
CAUSE #3: If thermal cut out has tripped: the unit will remain
auto-off and wait until inlet & outlet temperatures fall below a
normal value and a manual reset.
SOLUTION #3: Just wait until reset temperature is reached
and power back on the unit.
If this is proved to be the case, it has to be further investigated since thermal cut out only takes
place at high water temperatures. For example, check for air bubbles on the system.
CAUSE #4: Flowswitch failure.
SOLUTION #4: Check if flow switch is working properly and replace if necesary.
RCD SWITCHS IMMEDIATELY AFTER POWERING ON THE HEATER
CAUSE: One or more triacs failure due to a high voltage peak from electrical supply.
SOLUTION: Replace triacs.
UNIT IS SWITCHED ON AND WORKING BUT AFTER MANY TIME NO WARMER WATER APPRECIATED
CAUSE: Heating elements out of order.
SOLUTION: Check resistance between the poles of the heating elements. Replace if necessary.
DISPLAY SHOWS INCORRECT TEMPERATURE: -32ºC / -25ºF
CAUSE: Temperature flow connector is incorrectly connected.
SOLUTION: Check that all pins in the connector are correctly
connected. Check images Nº13.
CAUSE #2: Power PCB or logic PCB failure.
SOLUTION #2: Check and replace if necessary.
CAUSE #2: Water flow near minimum value due to
dirt in filter.
SOLUTION #2: Back wash the filter to restore flow.
