The Leader control has been turned off by the Enter/Reset button on

 

 

the Smart System display.

 

 

 

 

 

 

 

 

 

Cas: Standby

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

 

 

thermostat.

 

 

 

 

 

 

 

 

 

Cas: 127.4F (130)

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

#9

 

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.

boiler called on. The second percentage shows the total power

 

available to the Cascade.

 

 

 

Shows the number of boilers connected to the Cascade. The Leader is

 

designated as 0. Members will be designated 1 - 7. If a “-“ is used in

Present: 01234567

place of a number, that boiler is either not connected, or in a lockout

mode and not available for the Cascade. If a “d” is used in place of a

 

Example:

number, that boiler is handling a DHW demand and is not available

for the Cascade. If the number is flashing, then that boiler is providing

Present: 23----d1

heat to the Cascade. As the lead boiler is changed from day to day, that

 

 

boiler’s address will be shown first in the string of numbers. In the

 

example, boilers 0 - 3 are present, boiler 2 is the lead boiler, and boiler

 

0 is heating an indirect DHW tank.

Press the Next ￿ arrow key on the SMART SYSTEM display to roll back to Screen #1. At any point if you wish to access an earlier screen, press the Previous ￿ arrow key on the SMART SYSTEM display.
