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 8-13 for 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.
