This parameter represents the lead lag firing rate when frost protection is enabled.
5-19 Lead Lag Advanced Setting: WWSD Parameter
5-19.1 To Enable Or Disable Lead Lag WWSD
ConfigureLead Lag Master Configuration Advanced Setting WWSD Enable Textbox (Default: Disabled)
x Select Disable to disable WWSD
x Select Shutdown after demand ended to allow any current CH demand that is present prevents WWSD from
becoming true
x Select Shutdown immediately to allow WWSD to become true immediately causing CD demand to end
5-19.2 To Change WWSD Setpoint
ConfigureLead Lag Master Configuration Advanced Setting WWSD Setpoint Textbox (Default: 90ͼF)
x Type in desired temperature between 32ͼF and 240ͼF (0ͼC and 115ͼC)
When the outdoor temperature is greater than Warm Weather Shutdown setpoint then it will cause the CH demand to
end. If there is no outdoor temperature then WWSD is disabled.
5-20 Lead Lag Advanced Setting: Algorithms Parameter
5-20.1 To Change Lead Selection Method
ConfigureLead Lag Master Configuration Advanced Setting Algorithms Lead Selection Method
Textbox (Default: Lowest measured run time)
x Select Sequence order to sequence the lead boiler according to their sequence order or Modbus address if this
value is zero
x Select Measured run time to sequence the lead boiler according to reported run time.
5-20.2 To Change Lag Selection Method
ConfigureLead Lag Master Configuration Advanced Setting Algorithms Lag Selection Method Textbox
(Default: Measured run time)
x Select Sequence order to sequence the lag boiler according to their sequence order or Modbus address if this
value is zero
x Select Measured run time to sequence the lag boiler according to reported run time.
5-20.3 To Change Lead Rotation Time
ConfigureLead Lag Master Configuration Advanced Setting Algorithms Lead Rotation Time Textbox
(Default: 1h0m)
x Type in desired time
This parameter is used to trigger the rotation of lead boiler. Note the rotation does not occur until the next heat
demand cycle.
5-20.4 To Change Forced Lead Rotation Time
ConfigureLead Lag Master Configuration Advanced Setting Algorithms Forced Lead Rotation Time
Textbox (Default: 24h0m)
x Type in desired time
This parameter is used to trigger the forced rotation of lead boiler. Action is forced and is independent of the heat
demand cycle.
5-21 Lead Lag Advanced Setting: Rate Allocation Parameter
5-21.1 To Change Base Load Common Rate
