Table 2-22 List of Optional Values for Display on Home/Summary Screen
Value Description
System setpoint Indicates the actual local CH setpoint (i.e. for a CH1 demand); adjusts for outdoor reset.
Operating temp
Indicates the temperature at the sensor used for burner modulation during a local CH or DHW
demand, i.e. boiler inlet, boiler outlet or system/pipe sensor.
Outlet temp Indicates the temperature reading from the boiler outlet sensor.
Inlet temp Indicates the temperature reading from the boiler inlet sensor.
Outdoor temp Indicates the temperature reading from the outdoor sensor.
Delta T Indicates the temperature difference between the boiler inlet and outlet sensors.
LL Operating temp
Indicates the temperature at the sensor used for burner modulation during a Lead Lag demand, i.e.
boiler outlet or system/pipe sensor.
LL System setpoint Indicates the actual Lead Lag setpoint [i.e. for a CH2 (LL) demand]; adjusts for outdoor reset.
Fan speed Indicates the speed that the combustion blower is running at – tachometer reading.
Flame signal Indicates the flame current sensed from the flame probe.
Firing rate Indicates the speed that the combustion blower is being commanded to operate at.
DHW temp Indicates the dhw tank temperature (if used) or OPEN/CLOSED for Aquastat switch status.
Stack temp Indicates the temperature reading from the boiler stack sensor.
4-20mA input
Indicates the input signal from an external 4-20mA source (used for direct burner modulation or
establishing temperature setpoint).
Lead Lag temp Indicates the temperature reading from an optional system/pipe sensor.
