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 [[#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. To adjust this threshold, see the [[#Threshold Adjustment|Threshold Adjustment]] section below. | ||
If this state is active, adjustment of the recirculation valve position should be considered. Since operating only in [[#Stage 1| Stage 1]] produces less heat, the ability to heat the pool is reduced. This is primarily an issue where the amount of heat loss in the pool exceeds the capability of [[#Stage 1| Stage 1]] heating (i.e. the pool cools faster than it can be heated). Consult with [[Board_Building_and_Grounds Building and Grounds]] if needed to properly adjust the valve positions. | If this state is active, adjustment of the recirculation valve position should be considered.
