Press to check the water level alarms. There is time delay for the burner to reach 1
st

(expansion option 22), allowing the operator to decrease the water level to check the 1
st
low alarm. If the
water does not drop to 1
st
low within this time, the shunt switch test is cancelled, and the MM reverts to
normal operation. There is additional delay (expansion option 23) to allow the operator to decrease the water
to 2
nd
low to check the 2
nd
low alarm. If the water level does not drop in this time, the MM leaves shunt switch
test and the burner will turn off. The timer will display when doing these tests. After reaching 2
nd
low, if the
water level does not rise to control point within 10 minutes, alarms will occur.
