Beckett 7600 manual Changing Domestic Hot Water Priority Dhwp Setting

c.To change the call for heat source that the circulator is activated from (see Figures 8 - 13 for examples), press the “▲” and “▼” keys until the following screen is displayed:





Press “ENTER (RESET)” to toggle the circulator source between ON TT, ON ZR, and ON BOTH.

4.Press “CANCEL (BACK)” to exit.

D.Changing Domestic Hot Water Priority (DHWP) Setting

The Domestic Hot Water Priority function temporarily overrides the HeatManager Dynamic Temperature Reset functionality when there is a call for domestic hot water. This ensures that hot water will be produced when needed. It also temporarily turns off either the C1 or ZC outputs (depending on the DHWP and circulator source settings) to give priority to the DHWP zone when it calls for heat. See Figures 8-13for examples of how to use these settings for maximum benefit.

F.Changing Low Water Cut-Off (LWCO) Setting

The Low Water Cut-off function is active when the 2-in-1 sensor is used with the AquaSmart control to prevent the burner from firing without sufficient water present in the boiler. The DELAY OFF time can be selected to delay the response of the control to a low-water condition. The DELAY ON time can be selected to delay the response of the control when the boiler water returns to a sufficient level. The RESET function can be set to AUTO or MAN (manual) to control how the AquaSmart will return from a LOCKOUT LOW WATER condition when the boiler water returns to a sufficient level. In AUTO, the AquaSmart returns automatically. In MAN (manual), the ENTER(RESET) button must be held for 5 seconds.
