Installer Settings are used to adjust functional operating parameters. To adjust, press and hold the SET button until the Temperature setting appears. Cycle through settings by depressing the SET button and using the Ў and ^ buttons to change the settings. Setting Code Description Range Temperature Domestic hot water setpoint. Default is 120°F 90-150 Differential Domestic hot water temperature drop before call for heat. Default is 10°F. 5,10* Post-Purge Early boiler shutoff prior to hot water setpoint. Circulator runs until setpoint. Default is 0°F. 0,4,8** Priority Temporarily cancels space heat to maxmize available energy for hot water. Default is 'n'. y/n Capacity Water heater capacity; select appropriate size for proper operation. Default is 41 Gallons. 26,41,60,80,120 BTU Transfer Real-time BTU transfer estimate in 1000 BTU/Hr increments. Diagnostic readout only. 0-199MBH/Hr *Available in Standard Mode only. **Available only when Differential setting is 10. Diagnostic Error Codes display a visual indicator and sound an alarm if a fault is detected. Codes clear automatically when corrected or can be reset by interrupting power to the control for 5 seconds. To silence an alarm, depress the Ў on the keypad. Error Code Description Potential Causes*** Temp Sensor Temperature sensor (thermistor) fault. Sensor unpluggedSensor damaged Overheating Domestic hot water temperature has exceeded maximum setpoint. Error in boiler plumbingZone valve stuck openLeak in sensor well Slow Heating Unit has taken over 60 minutes to reach hot water setpoint or cannot reach setpoint. Faulty equipmentFouled heat exchangerNo fuel Water Alarm Standing water detected. Standing water ***See Troubleshooting section for additional information Operating Indicators are used to display operational and functional status. Water sensor temperature may be shown for 30 seconds by pressing the ^ button. Indicator Code Description Startup Test Displayed briefly during intial powerup to test LED display segments. Idle Static numeric [setpoint] readout (factory default shown) indicates domestic hot water setpoint. Heating Alternating On and [Setpoint] is displayed during a heating cycle while the circulator pump contacts are closed. -7 -8- 7.

When installed, domestic water temperature is regulated by the boiler and the HYDROMAX aquastat is not used. 1. Unscrew and remove copper sensor bulb from sensor well. 2. Insert Universal Sensor to bottom of sensor well. 3. Plug Universal Sensor into Extension cable. 4. Connect wire leads to DHW input terminals on boiler control. 8. Startup Procedure 9. Troubleshooting PROBLEM POSSIBLE CAUSES SOLUTION 1. No power to unit 1. Check circuit breaker, boiler emergency switch and boiler reset switch. 2. Circulator air-bound 2. Purge air. Ensure circulator is on Boiler Supply. Check air vents. No hot water 3. Faulty circulator or zone valve 3. Check circulator and zone valve. Repair or replace if necessary. 4. Faulty control 4. Check continuity. Switching circuits should close. If not, replace control. 5. Boiler inoperable 5. Check boiler system. Boiler must operate to generate hot water. 1. Demand exceeds capacity 1. Check sizing based on household size and boiler output. 2. Temperature too low 2. Increase temperature setpoint. 3. Boiler lacks output for simultaneous heat & hot water 3. Set up for priority. If problem persists add storage or increase tank size. Insufficient hot water 4. Fouled heat exchanger 4. Check Boiler Supply/Boiler Return during cold startup. If diff...
