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.
