TO CHECK OR ADJUST THE PRESET OUTLET TEMPERATURE SETTING 

The temperature settings will be displayed on the LED display. The preset outlet temperature settings are: 

 

244 series 

 

38°C, 40°C, 42°C, 43°C, 45°C, 50°C, 55°C, 60°C, 70°C, 75°C 

 
It  is  necessary  to  have  the  electrical  supply  to  the  water  heater  switched  on  during  stages  of  checking  or 
adjusting the preset outlet temperature setting procedure. 
 

  Warning:

  The  removal  of  the  front  panel  will  expose  240 volt  wiring.  Take  care  not  to  touch  wiring 

terminals. The adjustment must be carried out by a qualified person. 
 

 Warning:

 This procedure  will involve the adjustment of dip switches.  Adjustment of a dip switch should 

only be made with an insulated tool. 
 
To check or adjust the preset outlet temperature setting: 

1. 

Switch off the electrical supply at the power outlet to the water heater. 

2. 

Remove the screws holding the front panel to the jacket. 

3. 

Gently disengage the front panel and pull forward to remove from the 
water heater. 

4. 

Switch on the electrical supply at the power outlet to the water heater. 

5. 

Switch dip switches 3 and 4 to the on (up) position on the DIP 1 set of 
DIP switches on the I.C. Board. 

The  current  preset  outlet  temperature  setting  will  show  on  the  LED 
display. 

If the temperature displayed on the LED  display  is the desired  preset 
outlet  temperature  setting,  then  proceed  to  step 7,  as  no  further 
adjustment is necessary. 

6. 

Press  the  MAX  button  to  increase  or  the  MIN  button  to  decrease  the 
preset outlet temperature setting. 

Each  press  of  the  MAX  or  MIN  button  will  increase  or  decrease  the 
preset temperature by one increment. 

The  MAX  and  MIN  buttons  are  located  underneath  the  DIP 1  and 
DIP 2 set of DIP switches. 

The increments are 38, 40, 42, 43, 45, 50, 55, 60, 70, 75. 

7. 

Switch dip switches 3 and 4 to the off (down) position. 

The  temperature  display  will  go  blank.  The  preset  outlet  temperature 
setting is now set. 

8. 

Switch off the electrical supply at the power outlet to the water heater. 

9. 

Refit the front panel and screws to the water heater.
