ALTERNATE USES FOR AUX 1 INPUT
AUX 1 input accepts any of the listed pressure or temperature sensors and can be utilized for a vari-
ety of purposes.
MONITORING PRESSURE - PRES
Using any of the listed pressure transducers, the user can monitor and display any pressure not
related to the boiler steam pressure. For example, on an oil fired boiler the user may want to install to
monitor burner oil pressure and have that information available to the display screen as well through
modbus communications.
STANDBY WATER - STNDBY WTR
Only AUX 1 can be used for STANDBY WATER. Refer to the previous sections explaining the
operation of STANDBY WATER.
MONITOR TEMPERATURE - MNITR
Using any of the listed pressure transducers, the user can monitor and display any temperature not
related to the boiler water temperature. For example, on an oil fired boiler the user may want to
install to monitor burner oil temperature or in a hot water system the return hot water. This informa-
tion is to the display screen as well through modbus communication.
STACK TEMPERATURE - STACK
A temperature sensor can be installed to monitor the stack temperature of the boiler. A high limit
alarm and marginal high limit alarm can be programmed for that sensor. When the high limit alarm is
exceeded, the BurnerLogix Z system will shutdown and lockout the boiler. The appropriate alarm
message will be displayed. When AUX 1 is selected as Stack Temperature (STACK TEMP), the user
has the option of sensor range, 32-350F or 32-752F. The user then programs in the MARGINAL
HIGH LIMIT (MRGNL STACK) followed by the HIGH LIMIT (LIMIT STACK).
