MODES OF OPERATION 

 
 

To Change Between Pool and Spa Setpoints Manually: 

This is the default factory setting (jumper on pins 1-2) and allows the user to change between the pool 
and spa setpoints by using the mode button located on the front control panel.  The use of an external 
water pressure switch 

IS

 

NOT

 required for this mode of operation.   

 

To Change Between Pool and Spa Setpoints Automatically: 

This change can be done automatically as the water flow is directed to either the pool or spa.  The use  
of an external water pressure switch in the spa piping 

IS

 necessary.  A two-wire control circuit must be 

connected from the water pressure switch to the terminals 9 and 10 on the terminal strip located in the  
electrical control enclosure.  The mode jumper must be on pins 2-3 for this mode of operation.  See  
figure 1 below for pin settings. 
 

Remote Thermostats and Controllers:  

If a remote thermostat or another control system is to be used to operate the heater, a normally open  
dry contact can be made at terminals 11 and 12 on the terminal strip located in the electrical control  
enclosure.  Remove the red jumper from terminals 11 and 12 on the terminal strip and install the  
remote control system.  The mode jumper must be on pins 3-4 for this mode of operation.  See figure 1 
below for pin settings.
