Module Introduction
The system consists of power box (GH21-PB), control module (GH21EE), Bluetooth module (GH21-BT) and steam module
GS08-HW. Power box (GH21-PB) provides 14v DC.
The keypad controls the system and there are two temp sensor connectors: internal temp sensor and external sensor.
When the external sensor is connected, the internal sensor will not work.
Then using the internal temperature probe, there will be 30 to 60 second delay.
Steam generator: controls steam function, water filling and draining.
Reset Introduction
Removing or adding of any modules, the steam generator will not work properly, unless power box is unplugged before
any changes and reconnected after the change.
Wiring:
The power module provides 14V DC and there are 6 connectors. If the wire isn’t long enough, user can extend it
with extension wire. All modules should be connected to the power module.
