CONTROLLER PROGRAMMING AND SERVICE CODES Section 1
1.1 CONTROLLER PROGRAMMING AND SERVICE CODES
2012 NRCan and DOE Compliance and Operation
Operation of this control may delay the burner operation while the residual heat is circulated
out of the boiler.
The integrated boiler control module provides ignition
sequence, flame monitoring and safety shutoff for
intermittent pilot spark ignition. It also provides limit rated
water temperature control for with two separate sensors in
one casing (3-wire).
The control is located on the front panel inside the boiler.
The control display, along with Up ▲, Down ▼, and “I” keys
may be used to view boiler operating status and program
parameters (Figure 1).
1.1.1 RUN MODE
In the RUN mode, status items and parameters are viewable.
Figure 1 Control Displa
To read settings, press and release the “I” key to find the parameter of interest. Each setting will
alternately flash between the relevant display code listed in the Table 1 and its corresponding value. For
example, press and release “I” key until “HL_” setpoint is displayed, it will then flash a three-digit number,
i.e., 220, followed by ˚F (or ˚C). This indicates that the boiler water temperature of 220 ˚F is set. Other
operating parameters display the settings in a similar fashion.
