Each module in the airQrate has one CaliControl board, this maintains the heater, the valves and does the interface to the ozone generator. It also includes Rs485 converters for the mass flow sensors. On some setups we use a I2C interface to communicate with other boards, connecting or disconnecting cables with power on gives you a 50:50 chance to destroy the boards! Always power off the unit!
