AquaSmart Circulator Configuration Error

Products affected:

Beckett AquaSmart Part Numbers 7600A and 7600B manufactured between 4/21/14 and 7/7/14 contain an error in the default configuration for the circulator. Only controls manufactured during this period have the error.

Results of problem:

The controls were configured to energize the circulator on a call for heat from the zone relay (ZR) instead of energizing the circulator on a call for heat from the thermostat (TT). As a result, when the thermostat calls for heat, the burner will fire, but the circulator will not be turned on. Water temperature will safely be controlled to the setpoint temperature, but no heat will circulate through the heating system.

Corrective Action:

Beckett has reconfigured inventory in our stock. An orange dot near the label and on the box indicates the control has been corrected. In the field, the default circulator setting can easily be changed using the display. During the installation of the boiler, please verify that the circulator is programmed correctly for the application (ON TT or ON ZR). Make sure the circulator turns on for the appropriate call for heat.

Please see below for step by step instructions for checking or changing the circulator setting.
