585 series BIC is a family of electronic devices that integrate both flame control and gas appliance regulating functions, implemented on the same card.
585 series BIC is designed for use with combination boilers, floor standing boilers, instantaneous water heaters with forced- or natural-draught atmospheric burners or premix condensing boilers.
The device can be applied to boilers with separate domestic water and central-heating exchangers or to those with integrated exchangers.
The device controls both the delivery temperature of the domestic hot water and that of the central heating circuit, giving priority to the domestic hot water supply.
Temperatures are regulated by means of a direct feedback from temperature sensors placed at the domestic hot water and central heating water delivery outlets.

Three different versions are available:

585.100 BIC (standard)

The 585.100 BIC is designed for mono or bi-thermic heat exchangers. It has an on-board igniter and can be connected to either a LCD or LED display module. For the comfort of the domestic hot water firmware for an external hot water tank program is provided.
The control also includes a modulating fan in order for the efficiency of the boiler to be as high as possible. In order to verify the correct operation of the control a PC-diagnostics port is provided in the control.
The board is configurable for both atmospheric as well condensing appliances.

585.200 BIC (premium)

The 580.200 series BIC is designed for mono or bi-thermic heat exchangers. It has an on-board igniter and can be connected to either a LCD or LED display module. For the comfort of the domestic hot water firmware for an external hot water tank program is provided.
The control also includes a modulating fan in order for the efficiency of the boiler to be as high as possible.
In order to verify the correct operation of the control a PC-diagnostics port is provided in the control. The board is configurable for both atmospheric as well condensing appliances. The difference with the 585.100 series is that this version has more I/O available for thermistors and high voltage outputs.

585.300 BIC (top)

The 585.300 BIC is designed for mono-thermic heat exchangers. It has an on-board igniter and can be connected to either a LCD or LED display module. This board features a special hardware that is used for driving an EC-motor directly instead of using an electronic board on the motor. This allows for the appliance manufacturer extra flexibility with respect to the design. In order to verify the correct operation of the control a PC-diagnostics port is provided in the control. An additional difference to the 585.100 and 585.200 series is that this control has enough inputs and outputs to also allow connection for a second heating zone.
