Setting the High Limit Temperature 

This sub-menu allows you to limit how high the temperature set point may be set. It also serves as a high 
limit safety, alerting you if bath temperature rises above the high limit temperature setting. The High Limit 
value may be set from +40° to +140°C / +100° to +285°F; the factory default is +140°C / +285°F. 

To avoid an unwanted shutdown during regular operation, the High Limit value should be set at least 5° 
higher than the selected control temperature. 

 

To Access:

 This Press the 

 key until HIGH LIMIT appears on the display. 

To Change:

 Press 

 or 

.  

To Accept:

 Press 

 or allow the LCD to return to the main operational display  

(approximately 10 seconds). 

Resetting the Factory Default Values 

You can return your Circulator to all factory-set default as follows: 

1.  Press the 

 

key to turn the Circulator OFF. 

2.  Unplug the power cord from the electrical outlet. 

3.  Plug the power cord back into the electrical outlet while pressing either the 

 

or
