Servicing should only be performed by a Qualified Service Agent
NOTE: When the installer proceeds with the safety parameter configuration, the control unlocks the safety parameters in this group
and marks them unusable. Failure to complete the entire safety configuration procedure leaves the control in an un-runnable state
(lockout 2).
All safety configuration parameters in the group should have the same access level. If this condition isn’t so, the user is asked to enter
another password when a higher access level is needed.
Successful login is noted by the lock icon, which changes to “unlocked” on the page. The installer may begin to change safety
parameters (or any other parameters) at that time (see Figure 39). If the Burner Control is in an unconfigured (or new) state, then this
warning doesn’t appear. All parameters that need changes should be changed during the login.
If the safety configuration session is terminated after it has started (in the Edit or Verify stages), the Burner Control is left in an
unconfigured (unrunnable) state.
The installer can terminate the session by pressing the Menu button or by attempting to leave the Verification page with the Home or
Back buttons (top-left and top-right screen corners, respectively). However, leaving the session at this point leaves the control in an
unrunnable state and confirms whether the installer still wants to do so.
The settings of all parameters in each safety block must be verified to save them in the control.
When the installer is done changing safety parameters, pressing the Verify button on the configuration screen begins the Verification
process. The settings for all safety parameters in each changed block are presented and Verified by the installer (see Figure 40).
Press the Yes button to confirm each safety parameter block. If the No button is selected, the safety parameter block remains
unconfirmed and the Configuration menu page is displayed. The control remains in an unconfigured state in this case.
After all safety parameter blocks have been confirmed, the installer is asked to press and hold the Reset button on the Burner Control
to complete the safety verification session (see Figure 41).
When the Reset button is pressed and held for 3 seconds the confirmed safety parameters are saved in the control. The above Reset
dialog box automatically closes when this step is completed. If this step is not performed, the control remains in a safety lockout state
until the installer resolves the unverified safety parameters.
