CONFIGURATION
8.D.4.a Cascade CH
To navigate to the Cascade CH Conguration Screen, touch the Cascade Icon on the Conguration Screen, then
touch the Cascade CH Icon on the Cascade Conguration Screen.
The Cascade CH Conguration Screen allows
adjustment of the following parameters:
•
Address – When manually addressing each boiler/heater for cascade operations, this parameter is used to set the
local boiler/heater address. Each boiler/heater must have a unique address. A boiler/heater with a value of 0 is the
Lead boiler/heater. Lag boilers/heaters use values 1 through 7. When automatically addressing each boiler/heater, set
the Lead boiler/heater to a value of 0. With a value of 0, the Cascade Auto-Cong button is available to use, refer to
this parameter below for instructions for automatic addressing the Lag boilers/heaters.
•
Dynamic Address – This reects the address of the local boiler/heater after it has been manually or automatically
addressed. After a boiler/heater has been manually/automatically addressed, setting this parameter to -1 will remove
the boiler/heater from cascade operations.
•
Lead Settings – This button is only selectable when congured as the Lead boiler/heater. When congured as the Lead
boiler/heater, touching this button navigates to the Lead boiler/heater settings. See Section 8.D.4.a.1 on page 75
•
Lost Lead Backup Setpoint – When congured for Cascade Redundancy - Boiler Internal Set Point, this parameter
is the maximum outlet temperature the local boiler/heater is allowed to supply the system.
•
Lag On Hysteresis - The value below the Max Lag Temp (Max Lag Temp – Lag On Hysteresis) that the boiler/heater
will turn on to satisfy an active cascade demand based on the local boiler/heater outlet water temperature. Max Lag
Temp is set at the Lead boiler/heater.
•
LagOHysteresis- The value above the Max Lag Temp (Max Lag Temp + Lag O Hysteresis) that
the boiler/
heater will turn o when satisfying an active cascade heat demand based on the local boiler/heater outlet water
temperature. Max Lag Temp is set at the Lead boiler/heater.
•
CascadeAuto-Cong – This is only adjustable at the Lead boiler/heater. Once congured as the Lead boiler/
heater, pressing this button will initiate the Lead boiler/heater to nd and address all Lag boilers automatically.
•
Cascade Release Demand - When communications with the Lead is lost and the Lag units continue to satisfy the
cascade heat demand, pressing this button will remove the heat demand.
NOTE: This only applies when congured for cascade - Boiler Internal Set Point Control. See Section 8.D.4.d on
page 78
NOTE: All boilers/heaters must be wired for cascade operations
prior to performing Cascade Auto-Cong.
