TANK SETPOINT 

 

The  Tank  Setpoint  parameter  allows  the  setpoint  of  the  water  heater  to  be  adjusted  when  a  flow  temperature 
sensor is not used.  Lochinvar Limited recommends that a flow sensor is always used with this appliance. 
 

The setpoint should be adjusted to ensure that the water is stored at 60°C and distributed at 50°C within 1 (one) 
minute at all outlets.  Care is needed to avoid much higher temperatures because of the risk of scalding.  At 50°C 
the risk of scalding is small for most people, but the risk increases rapidly with higher temperatures and for longer 

exposure times.  The risk to young children and to those with a sensory or mobility loss will be greater.  Where a 
significant scalding risk has been identified, the use of thermostatic mixing valves on baths and showers should be 

considered to reduce temperature, these need to be placed as close to the point of use as possible. 
 

The default value is 60

C.  To modify the temperature setting, the 

Up

 or 

Down

 button should be used and the 

Enter/Reset

 button pressed to store the desired setting. 

 

3.6

 

EXITING USER SETTINGS MODE 

 

To  exit  the  user-setting  mode,  the 

Menu/Exit

  button  should  be  pressed  whilst  in  the  Main  Menu  screen.  

Alternatively, if no button is pressed for 60 seconds, the water heater will revert to its  normal operating screen.  

Once this has occurred, the 

Enter/Reset

 button should be pressed to switch the unit on.
