A. Controls
1. This boiler uses a proprietary version of the
Honeywell S9361A “integrated boiler control”
to manage all boiler functions including
flame supervision, temperature control, and
circulator operation. This control can operate
one or two circulator zones without the use of
additional relays.
2. In accordance with the 2007 Energy and
Independence Security Act, this control first
attempts to use residual heat in the boiler to
satisfy a space heating demand before firing
the burner. In this manual, this function is
referred to as a “thermal purge”. For additional
information see Part C of this section.
B. Reading Status And Using Menu
The boiler’s status, as well as all parameters, are
viewed and adjusted using the 3 digit LED and
three buttons shown in Figure 11.1. The S9361A
has four basic modes of operation (also see
Figure 11.2):
1. Status Mode - This is the default mode of
operation for the control. In it, the display
alternates between StA and a number
indicating the current status of the boiler. A
list and description of these status numbers is
shown in Table 11.3 and is also shown on the
face of the control itself.
2. Operating Mode - Provides additional
information about the current status of the
boiler. Operating mode is entered by pressing
the I button shown in Figure 11.1. When this
button is first pressed in Status mode, the
display will alternately display bt and the
current boiler water temperature as shown in
Figure 11.4. Pressing the I button again will
display the next line item shown in Table 11.3.
In the same manner it is possible to advance
through all of the “parameters” shown in
Table 11.3. To return to Status mode, press I
repeatedly until StA once again appears on
the display. Alternatively, the control will return
to Status mode if no key is touched for 30
minutes.
3. Error Mode - In Error mode, the control
alternately displays Err and an error code. A
list of these error codes is found on the front
of the control, as well as in Section 13 of this
manual (along with suggested corrective
actions).
