OPERATION
Timed Heating Profile
The oven is provided with a timer system that can run the oven in a steady-state heating profile at the
current temperature set point from 1 minute up to 99 hours, 59 minutes. Allow the oven to heat to
temperature prior to launching the profile. Launching a profile with the temperature set point set to 240°F
immediately after turning on the oven will result in the first 22 minutes of the profile being spent with the
chamber rising from room temperature to 240°F.
When the timer system is on, the oven will not heat unless a profile is running.
Accessory Power Exhaust Outlet
CDO forced-air ovens come with an external accessory power outlet intended to supply electricity to
accessories attached to the oven exhaust vent. The outlet is always powered while the oven is on. The
primary application of the power exhaust fan is to positively vent exhaust out of the workspace around the
oven. The standard receptacle is a 240 volt, North American 6-20R.
The operation of the fan affects the oven chamber temperature, lowering it significantly by boosting the
rate that cooler outside air is pulled in.
The Over Temperature Limit System
The oven is equipped with a heating cutoff system which automatically cuts off electricity to the oven
heating elements when the chamber air temperature exceeds 356°F (180°C). This is intended to help
prevent runaway heating in the event of a controller failure or if an outside temperature source
generates a heat spike in the oven chamber. The Over Temperature Limit heating cutoff is a
mechanical system that operates independently of the main digital temperature control system and
comes equipped with its own hydrostatic temperature probe located in the oven chamber.
