Parameter Range Description
BOILER SUPPLY
---, -22 to 266°F
(-30 to 130°C)
Current boiler supply water temperature as measured by the boiler supply sensor. “---”
is displayed if there is a sensor fault.
BOILER TARGET
---, -22 to 266°F
(-30 to 130°C)
The boiler target is the temperature the control is trying to maintain at the boiler supply
sensor. “---” is displayed when no heat is required.
PLANT OUTPUT 0 to 100% The plant output is the combined firing rate of all the boilers together.
SYSTEM INPUTS
CENTRAL HEATING
TARGET
---, 50 to 230°F
(10.0 to 110.0°C)
Central heating target as determined by outdoor air reset. “---” is displayed if there is
not a central heating call.
DOMESTIC HOT
WATER TARGET
---, 50 to 230°F
(10.0 to 110.0°C)
Domestic hot water heating target. “---” is displayed if there is not a DHW call.
SETPOINT TARGET
---, 50 to 230°F
(10.0 to 110.0°C)
Setpoint heating target. “---” is displayed if there is not a Constant Setpoint or Remote
Setpoint call.
OUTDOOR
TEMPERATURE
SENSOR
---, -85 to 149°F
(-65.0 to 65.0°C)
Current outdoor temperature as measured by the outdoor sensor. “---” is displayed if
there is no sensor available or there is a sensor fault.
DOMESTIC HOT
WATER TANK
---, 32 to 266°F
(0.0 to 130.0°C)
Current indirect DHW tank temperature as measured by the DHW sensor. “---” is displayed
if there is no sensor connected or there is a sensor fault.
PRESSURE
SENSOR
0 to 150 psi
(0 to 1034 kPa)
Current system pressure as measured by the pressure sensor.
This item is only available if the Pressure Sensor is ON. “---” is displayed if there is no
sensor connected or there is a sensor fault.
BOILER 1 TO 16 STATUS
FIRING RATE 0 to 100%
Current firing rate of the boiler. Applies to all boiler types except when using the EMS
output signal.
TARGET
TEMPERATURE
50 to 230°F
(10.0 to 110.0°C)
Current temperature target of the boiler. Applies only to boilers using the EMS output signal.
HOURS
0 to 999999
hours
Counts the number of hours that the boiler has fired since the parameter was last cleared.
CYCLES 0 to 99999 cycles Counts the number of boiler cycles since the parameter was last cleared.
