◊ The contactor K44 closes and the third leg of 220 VAC is sent to the 18
KW element (E4)
◊ If the reduced power option is chosen then the K44 Contactor is not
energized.
e When the condensate box is heated to 140 degrees F at the B3probe, 220 VAC is
sent from terminal 5 of connector X12 to the condenser valve (Y1) until the
temperature drops.
f If the “Crisp and Tasty” mode is selected
• 220 VAC is sent from terminal 6 of connector X12 on the Control Board
(A10) to the Dehumidification Valve (Y2) to pull the humidity out of the
cabinet down the drain.
◊ In the light and medium modes (one and two drops in the display) the Y2
valve will be energized until the bypass probe (B5) is satisfied.
◊ In the full mode (3 drops in the display) the Y2 valve will be energized
continuously.
g When the timer counts to 0 or the core temp probe (B10) reaches the set amount
the cycle ends and the steam generator reverts to the standby temperature of 190-
degree F.
7 With the combi in the Rethermalization mode with time on the timer, the door closed
and the start switch is depressed
a The front display will include a lighted bar under the Rethermalization symbol
• When the heat circuit is energized the heat symbol will be energized
• The cooking mode symbol will be energized.
• The time display will invert and begin to count down.
b The fan circuit is energized
• If the combi fan is in the normal setting 220 VAC is sent from terminal 5 on
connector X11 through the normally closed auxiliary contacts of contactor
K57 to the coils of contactors K55 and K56
◊ The K55 and K56 contactors close sending 220 VAC through the Q56
overload to the motor and the motor turns at a high speed.
◊ The normally closed auxiliary contacts of both K55 and K56 open
preventing the K57 contactor from energizing.
• If the combi fan is in the reduced setting 220 VAC is sent from terminal 6 on
connector X11 through the normally closed auxiliary contacts of contactors
K55 and K56 to the coil of contactor K57
◊ The K57 contactor closes Sending 220 VAC through the Q57 thermal
overload to the motor and the motor turns at a reduced speed.
◊ The normally closed auxiliary contacts of K57 open preventing the K55
and K56 contactors from energizing.
• For the first 2 minutes 220 VAC is sent from terminal 4 on connector X11
through the normally closed auxiliary contacts of contactor K5 to the K50
contactor coil
◊ K50 contactor closes and the motor turns CW
◊ The normally closed auxiliary contacts on K50 open preventing the K5
contactor from energizing.
