2. Set temperature lock on or off
3. Belt time lock on or off
4. Degrees Celsius shown, or default degrees
Fahrenheit.
Press

screen should appear as below.
Press
until the item you want to change is
flashing, then press
. Now press
until the
setting you desire is displayed, then press

D. Energy Management Information
The X70/X55 oven reduces energy usage in two ways
over most competitive ovens:
−
Modulating gas control (Energy
Management System)
−
BAKING / IDLE mode control (Energy
Saving Mode)
The modulating gas valve within the oven controls
pressure of the delivered gas to the burners to
increase or reduce the energy input as needed to
maintain temperature instead of cycling a gas valve on
and off. This is a most efficient and accurate way of
controlling the temperature and eliminates the heat
losses associated with the ON/OFF cycling control.
The X70/X55 oven, like other Middleby WOW ovens,
has an idle mode that places the blowers at a reduced
speed during non-baking periods. Reducing the
blower speed reduces the volume of air requiring
heating and thus reduces energy usage during these
non-baking times. A photo eye sensor at the entrance
side of the baking chamber detects when food is
placed on the belt and brings the oven up to the higher
(baking) blower speed, increasing the amount of
convection / impingement air needed to cook products
faster. When the product passes the photo eye, the
controller begins a preset timed period that ensures
the product will pass fully through the oven before the
oven returns to the IDLE mode. With this energy
management system, the oven provides the increased
convection / impingement heat transfer into the
products needed for fast, even baking, without the
energy penalty during non-baking times. This
functionality is fully automatic and requires no user
interaction.
