Functions: The module is designed to control the operation of a fan coil unit. The module can be managed from the panel via the MODBUS protocol or from the Sinum application via the Sinum SBUS protocol. The controller can support both 2-pipe and 4-pipe systems. The module supports a fan and valves controlled by a 0–10V signal or by 230V voltage. The control method for the connected device must be selected in the Sinum application or via the P-KL1 / P-KL3 panel. The module firmware can be updated in the Sinum application or via the USB port (in case there is no connection to the Sinum system). The module can work with both wired and wireless window opening sensors. Power supply: 230V AC. The module can operate independently using the PKL panel or together with the SINUM controller via SBUS communication.
