SmartPID M5 PRO basic concept
Designed for the industrial and pro market to manage any thermal regulated
application bridging the gap between complex and expensive industrial controller
(PLC) and simple on/off thermostat.
The flexibility, feature richness and smartness make smartPID M5 PRO a unique
product on the market that can replace legacy thermostat and manage any
application in a smart way !

Bluetooth temperature sensor pairing
● Navigate to the BT Sensor config menu (HW setup)
● Select “Pairing” menu then perform sensor scan
● The BT-05 sensors must be powered on (press central button)
● Select the BT05-xxxxx sensor and confirm
● Check the pairing status in the “status” menu
● In the BT config menu you can configure
○ Sample Time
○ Transmission Power
● Once paired the sensor BT05-xxxxxx will be available in the
HW config/sensor type menu as any other wired sensor

(wifi,cloud server)
Start
select standard or advanced mode (profiles), select
the set point and start the control process
Monitor
temperature on both channel is monitored. With
up/down button is possible to select the output (DC or
relay) and with SET activate the output
Setup
●HW setup --> the HW resources are
configured and assigned to I/O process
●Unit Parameter--> the main parameter that control
the PID process behavior are configured in this
menu
●Process parameter--> smart thermostat process
specific parameter are configured in this menu
●PID auto tune--> this is a special section to
configure and run the auto tune process to help
end user to calculate critical parameters Kp,Ki,Kd
that regulate PID behavior

SmartPID M5 PRO - process parameter
Parameter Description
Set Point 1 & 2 Default temperature set point for CH1 and CH2
Timer 1 & 2 Default countdown timer for CH1 and CH2
PID 1&2 Kp Ki Kd Define the proper constant value for the PID algorithm tuning for CH1 /CH2
Reset DT 1 & 2 Define temperature variation from set point to reset the count down timer
Fridge delay 1 & 2 Define the duration of the fridge protection timer (0 means no delay logic)
Sample Time Define the sample time of temperature in ms
PWM Period Define the PWM period/window size for PWM control in ms
Ramp/Soak Define if the control logic is dynamic or static (see proper section)
Sound Alarm Define for each alarms if the buzzer is activated or not

SmartPID M5 PRO - profile definition
In the menu “profile” it’s possible to create/modify/view/delete temperature profiles
to be selected in the advanced running mode.
For each point of the profile user should define:
SP X that is the starting set point temperature
Ramp Time Y that is the time to move set point from X to X+1
Soak time Z that is the time the temperature is kept constant
If the ramp time = 0 the set point is moved instantly (step)
If the next step has soak time=0 (or is the eight steps) the SP
is moved to that value and is kept constant until the process
abort by user

SmartPID M5 PRO - ramp/soak
Ramp/soak = STATIC
Soak time start when ramp time finish independently from
temperature. Each soak period is predefined and is
independently from the current temperature and set point.
After each soak period a new set point is defined and a RAMP
time defines the time needed to reach the new set point. SP is
moved linearly from SPx to SPx+1 with increment of 1c/40f
If the next step hast soak time=0 (or is the eight steps) the SP
is moved to that value and is kept constant until the process
abort by user
Ramp/soak = DYNAMIC
Soak time start when temperature reach the set point. When
the temperature reached the SPx the soak period is started.
After each soak period a new set point is defined and a RAMP
time defines the time needed to reach the new set point. SP is
moved linearly from SPx to SPx+1 with increment of 1c/40f. If
the next step hast soak time=0 (or is the eight steps) the SP
is moved to that value and is kept constant until the process
abort by user.
