DIP Switch Settings 

The DIP switches are pre-set at the factory and should not need to be adjusted. However, 
sometimes during installation they get changed accidentally.  

1.

 

The Dual Set Point controller is designed to operate as either a wind alarm or temperature 
alarm. The DIP switch marked "Wt" determines which mode is selected. Set this switch to 
ON for temperature alarms. 

2.

 

The "Wu" switch sets the wind speed units. This is not relevant to the temperature alarms, 
so it doesn't matter how this switch is set. 

3.

 

The "Tu" switch sets the temperature units. Set the "Tu" switch to OFF to display 
temperature in degrees Fahrenheit (°F). Set the switch ON for degrees Celsius (°C). 

4.

 

The "Si" (silent) switch determines whether the internal buzzer operates. The normal 
setting is OFF which allows the buzzer to operate. The ON setting silences the buzzer. 

The controller checks the positions of the DIP switches when the unit initializes during power-up. 
Disconnect the AC Adapter for a few seconds and then re-connect power to change modes after 
changing any switches.
