PART 6. START-UP PROCEDURES
D. INI PROCESS AND SERVICE PROCEDURES (continued)
To force an INI to run
(this can be done by all appliances in the cascade or individually):
1) Enter Setup menu
2) Press the back and down arrow simultaneously for 3 sec., to
enter the password screen, and enter password level 1 (there is
an advanced Level 2 with more options, available if you have
attended training at the Manufacturer's factory).
• Installer level – EAZ1LVL
3) The setup screen will now have additional selections, scroll
down to start INI (be sure only to select Zero if you have had a
commissioning issue and need an updated proper baseline to
work from), and select it.
4) The INI is now in progress, and will end after a few minutes at
which point normal operation will resume. A scrolling message
across the bottom of each appliance (if in a Cascade) will indicate
it is in process.
Note that the INI process normally occurs in the background, during
no call for heat and is rarely noticed. Subsequent INI’s happen on
a pre-determined basis; they are based on parameter IN1 setting
of 1 – 30 days and therefor can be adjusted to fit the environment
of the installation. If, you have an operation that requires heat 24
hours a day, when the system setting of days between INI’s has
been reached, and there is a burn cycle in process, the controls will
look to parameter IN2; waiting hours of burn time before a forced INI
occurs; default setting of 2.5 hours. When that quantity of hours has
been reached after the days between setting, a forced INI will occur.
A forced INI occurs like this; the burners of all appliances in the
Cascade (or the stand alone appliance) are shut down, the pump is
run until the gradient (moving temperatures) between the Inlet (T2)
sensor and the outlet (T1.2) sensor is less than parameter IN3; with
a default setting of 0.36°F/second ∆T. At the moment that setting
has been reached, the INI process begins and will take a minimum
of 3 minutes for a stand-alone or dual appliance system, and 7 – 8
minutes for up to 8 appliances in the Cascade.
The Cascade operating control remembers the settings of all running
appliances prior to the forced shut down and immediately following
the INI, it returns to those firing rates to minimize any drop in
system water temperature.
From the Home screen, you can navigate to the HISTORY tab,
select it and tab down to INI DATA, there you can view the recorded
INI data from record 00 (Z-INI) through the last 9 that have been
recorded. This is the data that decisions and notifications (if opted
for) will be sent based on.
