Cleveland Range Convotherm Combination Oven-Steamer Electric 6.20 - Manual (Page 88)

• 220 VAC is sent from terminal 3 of connector X12 on the Control Board
(A10) through the normally closed auxiliary contacts of K2 and K1 to the coil
of Contactor K4 until the cabinet reaches the set temperature as sensed at
probe B6.
◊ The contactor K4 closes and to legs of the 220 VAC is sent to the 18 KW
element (E4)
• 220 VAC is sent from terminal 7 of connector X11 on the Control Board
(A10) to the coil of Contactor K44 until the cabinet reaches the set
temperature.
◊ 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.
d
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.
e
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.
f
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.

With the combi in the Combi 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 combi 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
