Modes of Opera tions [Service se tup setting 5 ]:
Modes of OPERATION - This bo ile r can op erate in 3 d ifferent modes.
HEAT FILL
– Standard operation the boiler will take in water until the
temperature in the tank drops, the in le t will clo se and the heating element is
activated. W hen the temperature reaches the set temperature the in let will
reopen to take in more wate r. This cycle will continue until the Tank is Fu ll.
This mode is used to ensure that the water tempe rature is contro lled within set
va lues.
CONTINUOUS MODE
– In this mode the boiler will take in water and activate
the element until th e tank is full and th e temperature has reached the set
temperature. T ypically used in h igh de mand situations wh ere the temperatu re
stability is not prim ary con cern.
COOL Mode
– In this mode the temperature can be adjusted up or down
[function 1.] wh ile in operation. Depe nding on the wate r le vel in the tan k
selecting a lower temperature will cause either a message to “DISPENSE
WATER TO COOL THE TANK” or will automatically take in cooler water to
reduce the tempera ture to the ne w set temperature. In ap plications where
selectin g d ifferent temperatures fre que ntly is re quired this Cool Mode is best
selected.
