Parameter and Description
Master Enable/Disable
The Sequencer Master Enable/Disable is used to "turn on" the Multiple Boiler Controller. Warning! enable
ONLY one Sequence Master.
indirect Water Heater (iWH)
Boiler Piped Sequencer to respond to an Isolated DHW demand that is piped to a single boiler. The
individual boiler goes on "Leave" from the Sequencer Master and goes to DHW Service.
Primary Piped The Sequence Master responds to the DHW Call For Heat. This allows one or more
boilers to provide heat to the IWH.
DHW Two Boiler Start
The Sequencer to immediately start two boilers for a DHW call for heat. Used when DHW is the largest
demand. Only visible when primary piped IWH is selected.
Stop all Boilers Setpoint
When this temperature is reached all boilers are stopped. This setpoint allows the Sequencer to respond to
rapid load changes.
Parameter and Description
Boiler address
Each boiler must be given a unique address. When "Normal" slave selection order is used, the boiler address
is used by the Master Sequencer as the boiler start order. The boiler address is also the Modbus Address
when a building automation system is connected.
Slave Selection Order
"Use Boiler First"; places the Slave in the lead.
"Normal"; firing order follows boiler number (1,2,3,..) order.
"Use Boiler Last"; places the slave last in the firing order.
Response Speed
This parameter adjusts the Sequence Master temperature controller Proportion Integral Derivative (PID)
values. A larger Response Speed value results in tighter, more active, PID control. This speed is used
whenever the Sequencer is released to modulate.
