The temperature of the boiler's manifold is shown as the largest value on the display, in degrees Fahrenheit. A graphical bar below the measured shows the value relative to the typical minimum and maximum operating thresholds. | |||

The simulated screen captures below show various operating conditions that the user may encounter. The measured temperature and thresholds shown may vary. | |||

The OP1 and OP2 beacons at the top of the display indicate that both [[#Stage 1| Stage 1]] and Stage 2 | The <tt>OP1</tt> and <tt>OP2</tt> beacons at the top of the display indicate that both [[#Stage 1| Stage 1]] and [[#Stage 2| Stage 2]] heating are enabled. At this time, no feedback is provided to the temperature controller to identify if either stage is active; external conditions/faults may prevent firing stages. | ||
==== No Stage 2 ==== | |||
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. | |||
If this state is active, it may be desirable to adjust the recirculation valve positions. 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. | |||
