2Hardware Configuration
SmartPID BBQ PRO hardware configuration is quite simple and consists in connecting temperature
probes included in the kit, PWM 4-wire fan and supply.
2.1 Probes Connection
SmartPID BBQ PRO is equipped with 4 independent channels for the temperature of the grill (1 x PIT)
and of food (3 x FOOD) control.
Type NTC probes use 2.5mm connectors.
From the HW configuration menu, you can select “beta” value for each channel.
Supplied probes in the KIT have a beta value equal to 3950 (default value).
Finally, it is possible to make a temperature calibration, read by the probe with positive or negative
offset up to 5°C independently on each channel.

C2 General
2.2 FOOD Master
SmartPID PRO controller features 3 inputs for temperature probes, one of these inputs assumes the
role of FOOD MASTER. All advanced control functions requiring a “food” temperature value, always
relate to FOOD MASTER.
From HW configuration menu it is possible to determine which of 3 food channels is MASTER to
controller ignition.
During the control process it is always possible to change the assignment of food master, both from
the menu and from the remote control web app.
During run mode, to change default assignment you should press SET button and then select with
Up/Down buttons master probe and confirm again using SET button.

2.3 Fan Connection
SmartPID BBQ PRO supports 12V DC 4-wire fan with speedometer and PWM speed control.
The kit is provided with a pre-configured PWM 4-wire fan.
Fan connector has a direction of insertion, pay attention to tabs without stressing the connector.
It is possible to establish the operating range of the fan by limiting the maximum and minimum fan
speed, acting on Min/Max Fan Speed parameters in “Process Parameter” configuration menu. By
doing so the fan can be adapted to your own system, setting out a “virtual” fan with a limited scope
compared to actual maximum capacity.

2.4 Servo / Aux Configuration
SmartPID BBQ PRO controller also comes with an output for the control of a servomechanism
(mechanical control of fans) and of an auxiliary output 12V DC (for instance to check an electro valve).
In the configuration menu of process parameters, you can define the rotation angle of the
servomechanism.
Please Note: servo assisted valve is provided as an accessory and it is not in the KIT’s initial
equipment.

3Operating Principle
SmartPID BBQ PRO controller operating principle is based upon the control of airflow over coal to
increase or decrease the temperature inside the cooking chamber.
The greater air/oxygen supply, the higher the temperature.
Automatic check is done by constantly tracking the temperature on PIT channel and by continuously
modulating fan speed, thus air flow, from 0% to 100% by means of the PID –PWM algorithm.
Such control allows to keep temperature in the cooking chamber at a constant and predetermined
value in a stable and clean manner.
The PID –PWM algorithm will adjust fan speed always in 0-100% range but the actual value of
rotation speed will be scaled accordingly, depending on MIN/MAX fan speed.
Essential parameters regulating PID algorithm operation are Kp, Ki and Kd constants.
Please refer to a proper tutorial for the calibration process of such values.

4SmartPID BBQ PRO Advanced Features
SmartPID BBQ controller is equipped with an array of advanced features in support of cooking
process, hereafter is the description and guide to related parameters configuration.
4.1 Alarm Thresholds
PIT and FOOD MASTER channels are characterised by a set of temperature thresholds to which
specific alarms and notifications are linked. These values are defined by process parameters and can
be modified during run mode by pressing S/S button and UP/DOWN buttons.
PIT HI Alarm
Indicates a maximum threshold temperature value of channel PIT and in automatic run
mode is the set point target value for PID algorithm.
PIT LO Alarm
Indicates a threshold value on PIT channel that causes an alarm if current temperature drops
below such value (depletion of coal). Such alarm is not triggered if temperature did not
formerly go over cut-off point.
FOOD MASTER HI Alarm
Constitutes the target value of FOOD MASTER channel, namely the achievement of cooking
food temperature. Once is reached, the event is notified and a countdown timer is activated.
If configured, is moreover activated the rest mode (see after).

4.2 Lid Open Function
“Lid open” function enables to automatically intercept lid open with subsequent sudden decrease of
grill channel temperature, preventing unwanted fan speed boost.
The algorithm is ruled by two parameters which indicate percentage variation of temperature and
the term of observation window expressed as sample numbers of sampling window.
In case of % temperature variation over the observation period, fan is brought to MIN FAN speed
value for a configurable period of time (Lid Open Timer).
It is even possible to enable/disable LID OPEN mode manually, by simultaneous pressing of UP+SET.
Once finished the LID open timer (or when is reached the set point) the fan is reactivated and
monitored again by the PID-PWM algorithm.
Lid Open Mode % = 0 disables monitoring.
It is even possible to use this function in manual control mode, in such case as well the fan will be
forced to MIN fan speed in the event of lid opening.
4.3 Stall Function
Stall function is applied on FOOD MASTER channel and enables to detect a potentially harmful
situation in which core temperature does not increase in a predefined observation interval.

User Manual
16
C2 General
Stall function just provides an indication of audible and visual alarm, no action is performed on the
fan. When temperature starts to rise again, it exits stall mode.
Stall function is enabled in all three modes Monitor/Manual/Auto.
Stall function is active before reaching set point on FOOD MASTER channel (FOOD Alarm HI).
Stall function is regulated by hysteresis parameters i.e. a minimum range of temperature variation
and by the duration of observation window. If core temperature does not rise at least by hysteresis
stall, the stall is notified in stall window.
Stall Hysteresis = 0 control is not applied.
4.4 REST Function
With this function, once reached the FOOD channel set point (Set Point HI), fan speed is automatically
brought to MIN fan speed value, despite current temperature value on the grill and related set point.
The function, reached the cooking core optimum temperature, allows to minimise the temperature
in the cooking chamber.

User Manual

C2 General
4.5 Differential cooking function (Control mode Advanced)
“Differential cooking” function enables to track the cooking chamber temperature on the basis of
food’s core temperature.
Therefore, actual cooking programs can be created, with temperature profiles complex at will.
To each FOOD MASTER temperature value, a target value of PIT temperature is associated. Once
you’ve reached the value on FOOD MASTER channel, the set point on PIT channel is automatically
changed.
The fan management by means of PID-PWM happens consequently the change of PIT channel set
point.
It is possible to define a profile with up to 4 temperature steps.
Profiles configuration is essential before starting the advanced control mode by entering the
configuration menu.
4.6 Servo/Electro valve Management
By means of this function, once achieved in AUTO operation mode, the set point on PIT channel and
consequently of PID-PWM = 0% (min fan speed), it is possible to seal the air supply (vent-in) in order
to avoid the chimney effect and thermal drift in the combustion chamber.

User Manual
18
C2 General
To handle the lock of vent-in you need to insert a servomechanism that moves a slider or an
equivalent regularly closed electro valve.
You can set in process parameters the lag between the stop of the fan and the servo/electro valve
closure.
In case of servomechanism usage, it is possible to set the starting and rotation angle of the same, by
means of two parameters in the unit parameter configuration menu.
