ELECTRICAL CONNECTION OF THE HVAC UNITElectrical connection can only be implemented by the qualified electrician in accordance with the applicable international and national electricalsafety requirements and requirements for installation of electrical devices.Use only power source which meets the requirements specified on the device label.Power supply cable should be selected based on the electrical specification of the device. If the device power supply line is far from the unit, thedistance and voltage drop should be considered.Device must be earthed.Install the control panel at the designated place.Install the supplied connection cable(FLEX controller) between the control panel and the HVAC unit. It is recommended to install the control panelseparately from the power cables.Note: If cable is used together with other power cables, shielded control panel cable with earthed shield should be used.Connect the plug (RJ10 type) to the RS485-1 socket of the unit. Connect the other end to the control panel.RS458_1 RS458_2NOTE: The remote control panel can be connected and (or) disconnected only after disconnecting the power supply for the HVAC unit.Switch on the mains voltage, switch on the blade switch Q, see Fig. 5 (actual appearance of the blade switch can be different from the given photobased on the model of the product).OFFONSelect the desired fan rotation speed and the supply air temperature using the remote controller.
