The boiler temperature controller provides [[Low Operator]] and <b>High Operator</b> interlocks for the pool boiler. The role of each interlock in boiler operation is described in detail [[Pool_Boiler#Operation|here]]. | The boiler temperature controller provides [[#Low Operator|Low Operator]] and <b>High Operator</b> interlocks for the pool boiler.

The system described from hereon was created to enhance control and monitoring over the Johnson Controls C450CCN-3, which was in service prior to 2022. During the 2021 season, there were multiple observed instances of the boiler operating at a sub-optimal temperature. To prevent condensation, the boiler should operate at about 120 degrees or higher. This is achieved by mixing inlet water (ideally at 80 degrees or warmer) with water recirculated from the boiler outlet. This circulation pump is shown in the <b>Boiler Loop</b> section on page 2 of the [[Process Flow Diagram]]. | The system described from hereon was created to enhance control and monitoring over the Johnson Controls C450CCN-3, which was in service prior to 2022.
