UT 1018 Series Hot Surface Ignition

Status Indicator Error Conditions

The status indicator LED will not be lit with power applied to the board and the control operating properly.
However, if the control is not operating properly, the status indicator LED will flash in one of the following error
codes.

1. Status Indicator Flashing One Time

When the status indicator LED shows the error code of a single repeated flash, the control is in lock-out,
because the sail switch was stuck closed.

2. Status Indicator Flashing Two Times

When the status indicator LED shows the repeating error code of two flashes, the control is in lock-out
because the control circuits did not receive the “closed” signal from the sail switch within the required amount
of time.

3. Status Indicator Flashing Three Times

When the status indicator LED shows the repeating error code of three flashes, the control is in lock-out due
to either a failed ignition attempt, a gas valve error, or a false flame sensed during the pre-purge of warm-up
periods. If false flame has been sensed, the control will return to normal operation, and begin a new ignition
sequence when the false flame is no longer present.

4. Status Indicator Flashing Four Times

When the status indicator LED shows the repeating error code of four flashes, the control has gone into lock-
out due to a failure within the control board.
