To establish the setpoint source for a lead lag boiler plant start from the boiler
status screen and select conguration. From the conguration screen scroll to
and select lead lag master conguration and select the box labeled advanced
settings in the bottom right hand corner. Using the left and right arrow keys scroll
to the screen labeled central heat. The row labeled Setpoint Source needs to be
set on S2 (J8-6) 4-20mA. Refer to Figure 61 for factory default settings:
 O Hysteresis: The dierential above setpoint when the boiler is turned o.
 On Hysteresis: The dierential from setpoint when the boiler is turned on.
 4 mA water temperature: The setpoint valued assigned to a remote 4 mA
signal
 20 mA water temperature: The setpoint valued assigned to a remote 20
mA signal
For a standalone boiler the remote signal for setpoint must be congured
through a dierent screen. From the boiler status screen select congure and
scroll to and select central heat conguration. Using the left and right arrow keys
scroll to the screen labeled setpoint.
 Supply Header Temperature Sensor
The supply header temperature sensor is to be congured on the master boiler
only or a standalone boiler that may require a header sensor for modulation. For
further details on a standalone boiler application requiring a header sensor refer
to the supply header temperature sensor section of the electrical connections
and devices section. To congure a header temperature sensor start at the boiler
status screen. Select congure and scroll to and select sensor conguration. The
row labeled “*S5 (J8-11) Sensor” needs to be set at 10K NTC single non-safety. See
Figure 62.
For a lead/lag boiler plant the header temperature sensor will be referenced for
modulation by default. There is no additional conguration for the supply header
sensor in a lead lag boiler plant.
