The boiler temperature is greater than the [[#Stage 2| Stage 2]] threshold, and [[#Stage 2| Stage 2]] is disabled as a result. This is not a fault condition, though it may indicate sub-optimal operation. Only [[#Stage 1|Stage 1]] heating is enabled. | The boiler temperature is greater than the [[#Stage 2|Stage 2]] threshold, and [[#Stage 2| Stage 2]] is disabled as a result.

The [[#Stage 2| Stage 2]] threshold is the temperature value to the right of the <tt>Stg2</tt> identifier on the display, and should typically be set to TBD.

The boiler has not fired [[#Stage 1|Stage 1]] is response to a <b>Call for Heat</b>. This is an informational fault only; it does not disable either stage. This fault is only applicable if the <b>Call for Heat</b> signal is wired to the controller. | |||

The boiler temperature is less than the low-temperature threshold and both stages are disabled as a result. The low-temperature threshold should typically be set to TBD | The boiler temperature is less than the low-temperature threshold and both stages are disabled as a result.

This is a latching fault and must be cleared via the front panel before the boiler will operate. | This is a latching fault and must be cleared via the front panel before the boiler will operate. | ||
