WARRANTY -----------------------------------------------------------09
• In the event of defective operation or fault please ensure that the unit is turned off from the power
mains and contact your nearest authorised service agent.
• Ensure ALL valves are open before turning ON power to the pump and the Digiheat.
IMPORTANCE OF WATER CHEMISTRY
The DigiHeat has been carefully designed to withstand the harsh environment of a spa system,
and non metallic materials are used extensively. Where metals parts are used however such as
heater elements it is important that the water is chemically balanced to ensure that the water is
not corrosive or scale forming. Waterco will not be responsible for damage caused be corrosion or
scaling.
The chemical balance of water is a relationship between its pH, total alkalinity, calcium hardness
and temperature. Your professional pool or spa shop can test the water to ensure it is chemically
balanced in accordance with the Langelier Saturation Index. The water must be maintained at all times as per the following:
pH level : between 7.2 & 7.8.
total alkalinity : between 80 & 150ppm.
calcium hardness
: between 150 & 300ppm.
And within these tolerances to be balanced to the Langelier Saturation Index within a range of :
-0.2 to +0.2

HYDRAULICS & REQUIRED FLOW RATES
This equipment must be installed and serviced by a qualified technician.
Improper installation may result in property damage, serious injury or death.
Improper installation and/or operation will void the warranty.
1. The electrical wiring must be permanently hardwired by qualified electrician in accordance with
all the local wiring rules.
2. The appliance shall be supplied through a residual current device (RCD) having a rated residual
operating current not exceeding 30mA.
3. The DigiHeat must be installed within an area not accessible by any water or persons from within
the spa or pool.
4. The External Earth Bonding point is available for connection to alleviate cathodolitic corrosion of
the element.
5. A properly rated isolating switch must be connected from the supply to the DigiHeat with a
minimum rated power circuit as specified on the table below.
6. Parts incorporating electrical components except remote control device must be located or fixed
so that they cannot fall into the spa or pool.
This equipment must be installed and serviced by a qualified technician.
Improper installation may result in property damage, serious injury or death.
Improper installation and/or operation will void the warranty.
!
• Water must flow from left to right (when facing the DigiHeat).
There are arrows marked on the housing to assist in
determining the correct direction.
• The DigiHeat should be positioned upstream from any
chemical dosing or chlorinator and a check valve should be
installed to prevent corrosive water from flowing back into the
DigiHeat.
• In the event of DigiHeat being installed more than 1.8m below the pool water level the
adjustable pressure switch will not work. A flow switch must be installed in place of the pressure
switch.
• Required flow rates table
7. To access and carry out the electrical connections the front cover with the digital controller needs
to be removed. The front cover of the DigiHeat is hinged from the bottom to make it easier to
remove and replace it.
To remove the front cover :
i) remove the 6 spring loaded quarter turn locking pins first
ii) pull the cover gently from the top

To adjust the pressure switch:
• Switch OFF the power to the DigiHeat.
• Remove front cover of DigiHeat.
• Ensure the filter is clean & run the pump with the filtration system as normal (FILTER MODE) until
all the air has been bled from the system.
• Turn the pump OFF and check that the pressure switch turns OFF immediately or after a short
delay (1 to 2 secs). If it is not possible to hear the pressure switch operate, connect an Ohmmeter
across the Pressure Switch terminals.
• If the pressure switch remains ON after the pump stops, increase the operating pressure by
turning the small adjusting screw slowly clockwise until the switch turns OFF.

OPERATING THE DIGIHEAT
TEMPERATURE CALIBRATION (bias)
After familiarising yourself with the layout and settings of the touch pad (see previous section), fill the
spa or pool with water and follow the instructions below.
It is possible to have a temperature variation between the water in the spa or pool and the DigiHeat
controller. This is also referred to as the “Bias” adjustment setting. This adjustment can only be
carried out whilst the controller is set for “C” (centigrade).
We suggest that you instruct all the people who will use the spa or pool fitted with the DigiHeat on
how to operate it by either by giving them this manual or by showing them yourself.
Example: if the water in the pool or spa is 26º C and the DigiHeat control displays 24ºC.
Reading, understanding and following this guide should lead to trouble free operation of the DigiHeat
spa and pool heater.
To calibrate the temperature variation, set the bias to +2 with the following procedure:
1. Fill the spa or pool with water and then switch on the water pump.
2. With the use of an accurate thermometer read the pool or spa water temperature (e.g.: 26˚C).
2.Switch on the power to the DigiHeat. The controller will then display “OFF” or the water
temperature. If the pump is not running or if there is insufficient water flow, “nFL” will be displayed.
(Please refer to troubleshooting section of this manual for “nFL”)
3. If the display reads “OFF” press the on/off button to switch on the Digiheat, the temperature will
then be displayed.
4. Press and release the Up or Down button and the set temperature will be displayed with either
the ˚C or oF indicator LED flashing.
• To increase the desired set temperature press and hold the up button which will allow the
set temperature to be raised up to a maximum of 40˚C (104˚F). Release the button when the
desired temperature is displayed on the screen.
• To decrease the desired water temperature press and hold the down button. Release the
button when the desired temperature is displayed on the screen.
1. Switch on both the pump and the Digiheat.
3. Next read the temperature displayed on the DigiHeat control (eg: 24˚C).
4. To determine the bias setting subtract the pool or spa water temperature from the DigiHeat
Temperature.
Eg : 26 - 24 = 2˚C. Therefore we must compensate for the variation by setting the bias to +2.
If the temperatures were reversed eg; the water temperature was 24 and the Digiheat control was
26 we would require a bias setting of -2.
Eg : 24 - 26 = -2. Therefore we must compensate for the variation by setting the bias to -2.
5. Enter the programming mode by simultaneously pressing on the UP and DOWN arrows.
6. Once the temperature display is flashing press on the ON/OFF button.
7. Using the UP and DOWN arrows, enter the calibration value, (+2). In this case, by pressing the UP
arrow twice.(if the down arrow is used the bias will be a negative figure)
8. Once the bias has been entered wait until the calibrated temperature appears back on the display.
5. With an accurate thermometer check that the actual water temperarture in the pool or spa is the
same as the temperature displayed on the Digiheat.
If the displayed water temperature is different to the actual water temperature the controller will need
to be calibrated. This can only be done whilst the temperature is shown in ˚C. Refer to the following
section “temperature calibration”.
LOSS OF POWER
If the power supply to the Digiheat is lost, either by disconnecting it from the power supply or from
a “blackout”, when power is restored the DigiHeat will operate as follows,
1. If the Digiheat was “ON” prior to the power interruption, it will continue heating if the pump is
running and the set temperature is higher than the displayed temperature when the power is
restored. If the pump is not running the display will show nFL.
2. If the Digiheat was switched “OFF” prior to the power interruption, it will remain “OFF” when
power is restored.
EMPTYING THE SPA
If you intend emptying the water from the spa, disconnect the Digiheat and pump from the power
supply (isolating switch) to ensure the Digiheat will not be accidentally switched on while the spa is
empty. The pump can be damaged if it is run without water. Serious damage or injury may result.
