Base load rate adjustment

Description

Electrical Connection(s)

Programming Instructions

•

Upon a call for heat the lead
boiler will fire to the specified
base load rate (80%). If the
temperature is not within
Error threshold (5

F) of

setpoint after Interstage
delay (2 minutes) a lag boiler
will be brought online and
will also fire at the base load
rate specified.

•

Modulation of boilers will
only occur after all boilers in
the Lead Lag system are firing
at the specified base load
rate (80%).
