The
TO-751B
controller has been developed for automation of baking processes by controlling the
temperature and the process of dough proofers. The instrument allows the configuration of the type of process
and the start and end times for the fermentation cycle using an internal RTC (real time clock), providing
temperature control for both heating and refrigeration in dough proofers.
The
TO-751B
offers the possibility of controlling the humidity by using a temperature and humidity sensor
(SB56, sold separately), or using only a temperature sensor and setting a cyclic timer to activate the humidity
output, by adjusting the on and off times. It has a digital input used as a door opening sensor and another
dedicated digital input for the level sensor input (float ball), which monitors the oven's water tank, while also
allowing the activation of a solenoid valve when the water level detected in the tank is below the indicated level. It
offers an output to activate the ventilation, internal audible alarm (buzzer) or an output that can be used as
external audible alarm, selection the language of the main messages, and easy interface. It offers a function
access lock feature to prevent third parties from changing the parameters, airtight front panel that provides high
protection against the entry of dirt and moisture, and much more.

6.1 Operating modes
The
TO751B
controller can operate in two basic operating modes: Automatic mode (observing the
configuration of times and type of cycle) and manual mode of refrigeration or heating (configured by the user).
You can also turn off the control modes and keep the controller only indicating the temperature and time, i.e. the
outputs will not be activated according to the times or setpoints. The keys
,
, and
are used to select
AUT RE
HA
these operating modes.
When these keys are pressed, a message will be displayed to inform the selected operating mode, according to
the example:
Assuming that the current mode is auto mode and the user presses
intending to switch to manual refrigeration
RE
mode, the message
[mod]
[,OFF]
, will be displayed, indicating that the previous mode has been disabled.
Pressing
again will cause the message
[mod]
[rEFr]
, to be displayed, indicating that the manual
RE
refrigeration mode has been activated, i.e. when a mode is already active and you want to change to another
mode, press the corresponding key once to switch off the current mode and a second time to activate the desired
mode.
AUT
6.2 Indications of the operating modes
- When the controller is in automatic mode, led
will remain active, indicating the selected mode
AUT
- When the controller is in refrigeration mode, the indication will be as follows:
The led
will remain on while the refrigeration output is active;
RE
The led
will remain flashing when the refrigeration output is off but the refrigeration mode is selected,
RE
regardless of whether the process is automatic or manual;
- When the controller is in heating mode, the indication will be as follows:
The led
will remain on while the heating output is active;
HE
The led
will remain flashing when the heating output is off but the heating mode is selected, regardless of
HE
whether the process is automatic or manual.
AUT
6.2.1 Automatic mode
When the automatic operating mode is activated, the message
[mod]
[,Aut]
. will be displayed. In this mode
the controller will act in accordance with the times configured by the user for starting and ending the fermentation
cycle, observing the adjustment configured via function
[F13]
– Process Mode, where you can configure
which action will be taken by the controller after the fermentation cycle ends. Function
[F13]
– Process Mode
has three possible configurations:
-
[Cont]
Continuous mode: It allows keeping the controller controlling the fermentation cycle in continuous
mode in accordance with the configured times for starting and ending the fermentation cycles and with the days
selected to perform the fermentation cycles, which are configured in the function
[CYC]
in the user's menu. After
the fermentation cycle ends, the automatic mode will be maintained, keeping the refrigeration of the oven until
reaching the time to start a new fermentation cycle;
-
[SnG1]
Single mode without refrigeration at the end of the cycle: The controller will control the refrigeration of
the oven until reaching the time to start the fermentation cycle and the temperature control and the automatic
mode will be switched off after the end of the fermentation cycle;
