Assembly Instructions

This page explains the main control board interfaces, module connections, and basic assembly checks. It is recommended to verify each item after soldering.

Main Control Board

Connector Map

No.	Connector	Description
1	MX1.25 2P	Connect the main control board cooling fan. Pay attention to the polarity (+/−).
2	MX1.25 4P	Connect the AHT20 sensor module. Pay attention to the wire order.
3	MX1.25 2P	Connect the heater plate NTC thermistor. Polarity does not matter.
4	MX1.25 3P	Connect the PIR motion sensor module. Pay attention to the wire order.
5	PH2.0 2P	Connect the heater fan. Pay attention to the polarity (+/−).
6	ZH1.5 2P	Connect the LED strip. Pay attention to the polarity (+/−).
7	XH2.54 2P / 2510 4P	Connect either a 2-wire or 4-wire exhaust fan (choose one). 4-wire fans use PWM speed control, 2-wire fans use DC voltage control, 4-wire fans are recommended.
8	XT30	Connect the heater plate. Polarity does not matter.
9	XT60	Power input. Pay attention to the polarity (+/−).
10	LED strip supply voltage	12V/24V selectable. Solder the corresponding jumper pads according to your selected voltage.
11	Exhaust fan supply voltage	12V/24V selectable. Solder the corresponding jumper pads according to your selected voltage.

Voltage Selection Pads

Do not solder both voltage pads at the same time.
After soldering, use a multimeter to check whether the 12 V and 24 V lines are short-circuited.

Post-Assembly Checks

Power the board with USB only and confirm the screen turns on.
Enter the settings page and test touchscreen input and the EC11 encoder.
After connecting 24V, confirm the LED strip and fans rotate normally.
Before testing the heater plate, ensure over-temperature and over-current protection values are set correctly.

PIR Module

Set the jumper to H mode.
Turn the sensitivity adjustment clockwise to the maximum.
Turn the delay time adjustment counter-clockwise to the minimum.
