8. 7. Tighten draw nut until mounting clamp is firmly attached to well spud and wires are held securely in place. CAUTION Do not secure draw nut so tightly that mounting clamp collapses tubing. Fig. 8. Immersion well fitting for sensor. Wiring Disconnect power supply before installation to prevent electrical shock or equipment damage. All wiring must comply with local codes and ordinances regarding wire size, type of insulation, enclosure, etc. SENSOR WIRES M23086A HEAT-CONDUCTIVE COMPOUND (OPTIONAL) BOILER IMMERSION WELL SENSOR OPERATION AND CHECKOUT Operation The S9360A, S9361A, S9370A and S9371A continuously monitor the temperature of the boiler water and enable or disable the burner based on this temperature data. In general, when a “Call for Heat” occurs, the ignition portion of the control module proceeds through the steps necessary to start the burner and heats the water in the boiler until the setpoint temperature is achieved. At this point the burner is de-activated, the ignition module completes the heating cycle, returns to idle and waits for the temperature to drop again. The circulator is turned on throughout the “Call for Heat.” See Fig. 9 for a graphical representation of a simple control cycle. Note that the setpoint differential may vary based on OS number. High Limit Controller All models include a 3-wire temperature sensor interface, “Sensor 1,” which is utilized for High Limit functionality in addition to the thermostatic control of the water heater burner. If the temperature sensor ever indicates a temperature above the maximum limit then the control enters over temperature mode. In over temperature mode no heating will occur. 200°F (93.3°C) GAS VALVE OFF SETPOINT 15°F (8°C) DIFFERENTIAL GAS VALVE ON 70°F (21°C) M27000 Fig. 9.
