SmartPID M5 PRO User manual
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
● Check wifi connection status
● Select WiFi connection mode
(AP/client/Auto)
● Check WiFi parameters (SSID/PWD/IP)
● Check Server parameters (MQTT
address/credentials
Profile
● add/edit/delete temperature profiles
● up to 10 different profiles with up to 10
ramp/soak valued
Info
● display SW version
● start SW upgrade over the air (OTA)
● display serial number
● display status of various components
(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
