The Cascade is now active. The system supply temperature will be

 

 

displayed. The Cascade set point will be displayed in parenthesis.

 

 

 

 

 

 

 

 

 

Cas: Setpoint Met

The Cascade has met the water temperature set point, but is still

 

 

receiving a call for heat from a remote thermostat.

 

 

 

 

 

 

 

 

 

Cas: No Members

The Leader control could not detect any Member controls to

participate in the Cascade.

 

 

 

 

 

 

 

 

Cas: S6 Not Present

The system supply sensor is not connected to the Leader boiler.

 

 

 

 

 

 

PMP: Off

The Leader control has not received a call for heat from a remote

 

 

thermostat and has not powered the system pump.

 

 

 

 

 

 

 

 

 

PMP: On

The Leader control has received a call for heat from a remote

 

 

thermostat and has powered the system pump.

 

 

 

 

 

 

 

 

 

PMP: Delay

The system call for heat has been satisfied and the system pump is

 

 

running for a fixed time to remove any residual heat.
