using the FG Finder app.
BEFORE INSTALLING THE CONTROLLER, WE RECOMMEND THAT YOU FULLY READ THE INSTRUCTION
MANUAL TO PREVENT POSSIBLE DAMAGE TO THE PRODUCT.

THIS CONTROLLER IS NOT RESPONSIBLE FOR SAFETY WITH RESPECT TO ANY FLAME SENSOR, GAS
VALVE, OR SPARK IGNITER OF WHICH NEED TO HAVE SAFETY CERTIFICATES (RECOGNIZED IGNITION AND
GAS MODULE) IN ITS APPLICATION FOR FINAL USE. THE FLAME SENSOR, THE GAS VALVE OR SPARK
IGNITER IN THIS CONTROL WILL BE CONSIDERED SEPARATELY FROM THE THERMON CONTROLLER.

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-712B 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.

6. OPERATION

6.1 Oven: electric

In this operating mode the controller keeps the heating output on until the oven reaches the oven temperature
setpoint (SP). The heating output will be activated again when the temperature drops below the setpoint minus
the hysteresis [F04].

6.2 Oven: gas

In this operating mode the controller automates / monitors the flame ignition and thus the heating of the oven
through the activation of the gas output, ignition module, and flame sensor input. The controller keeps the heating
on until the oven reaches the oven temperature setpoint (SP).
Heating will be activated again when the temperature drops below the setpoint minus the Hysteresis [F04]. The
controller permanently monitors the flame sensor to ensure the safe operation of the gas-fired oven. In this way, if
there are any abnormalities, errors [Er4] - Flame Sensor shorted with the burner and [Er5] - Lack of Flame
are indicated. For more information, check item 9 (Signaling).

6.3 Oven: wood

In this operating mode the heating output works as an upper threshold alarm, indicating when the temperature
exceeds the value adjusted in Oven Temperature setpoint (SP). The audible alarm is also activated to warn the
user about the overheating. The output and audible alarm are switched off when the temperature drops below the
Oven Temperature setpoint (SP) minus the Hysteresis [F05] or when the
is pressed.

6.4 Default Mode (standard)

In this operating mode the controller performs the gas type control, however the flame sensor is ignored and the
controller will not monitor flame presence. The controller will not detect errors [Er4] - Shorted flame sensor and
[Er5] - Out of gas, resulting in an operation with less safety. Note: The Default Mode (standard) of operation is
available only when the type of oven is adjusted as gas. To execute this operating mode, check item 7.4 Enable
Default (standard) Mode of operation.
IN THIS OPERATING MODE THE FLAME SENSOR IS IGNORED AND THE CONTROLLER WILL
NOT DETECT THE PRESENCE / LACK OF FLAME, BEING ESSENTIAL FOR THE OPERATOR TO
PAY SPECIAL ATTENTION TO THE CONTROL OF THE OVEN IN ORDER TO PREVENT GAS
ACCIDENTS.

DESCRIPTION
Required when you want to change
installation setup parameters.
Selects the control type of the oven:
[ELE,]= Electric Oven
[GAS,]= Gas-fired Oven
[LEN,]= Wood-fired Oven
Defines the type of temperature sensor to
be used with the controller.
Selects the temperature unit the controller
will use for its operation.
Selects the language the controller will use
to display messages:
[Port]= Portuguese
[,EnG]= English
[,ESP]= Spanish
Enables or disables the external audible
alarm (buzzer). If enabled, the internal OFF
audible alarm (buzzer) will be disabled.
Selects the sound intensity of the internal
audible alarm (buzzer).
[Min,]= low volume
[Med,]= medium volume
[HiGh]= high volume
[,NO,]- normally open contact (NO)
[,NC,]- normally closed contact (NC)
Allows you to configure whether the digital
input will be used as an input for a door
sensor or as a digital input for high
temperature alarm:
[door] = Door sensor input;
[ALAr] = High temperature external alarm
input.
NOTE: When configured as a high
temperature alarm input, the other
functionalities related to the door sensor
consider that the door is always closed.
Enables stand-by mode (switching off
control functions).
