1. DESCRIPTION
Thermostat and timer for the automation of forced convection ovens. This model provides control over gas, electric, or wood
powered ovens, configured through the setup menu. TO-712F controls steam injection and lighting in the oven, and has an
internal audible alarm (buzzer) that signals, for example, the end of the roasting process. It also allows for the use of an
external audible alarm and the language selection of your main messages, improving the user experience. The ThermON
line is developed and produced with high-quality raw materials and stands out for its unique and differentiated design and
intuitive, user-friendly interface to facilitate operation and configuration. It offers a functions lock feature to prevent third
parties from changing the parameters, air-tight front panel that provides high protection against the entry of dirt and moisture,
and more.
