Operation - Crown Boiler AWR Series Installation Instructions Manual

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.
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.
The boiler's status, as well as all parameters, are viewed and adjusted using the 3 digit LED and three buttons shown in Figure
11.0. The S9361A has four basic modes of operation (also see Figure 11.1):
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 11.2
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 11.0. 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 11.3. Pressing the I button again will display the
next line item shown in Table 11.2. In the same manner it is possible to advance through all of the "parameters" shown
in Table 11.2. 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 XIII of this manual (along with suggested corrective actions).
4) Adjustment Mode - Used to change parameters, such as high limit setting. See Part C for using Adjustment Mode.
