Option with integrated hydraulic safety components available.) improved system reliability Two-directional communication board complying with Lon Talk Connects the unit by communication bus LON communication gateway protocol to a building management system Easy and high-speed connection by Two-directional high-speed communication using BACnet Ethernet line to a building management BACnet/IP protocol over Ethernet network (IP) system. Allows access to multiple unit parameters "Expands the remote control capacities to External management of the include a boiler on/off control. Control board factory installed on the unit for controlling a boiler boiler Facilitates control of a basic heating system" Expands the remote control capacities to include a maximum of four electric Management of electric heaters outputs enabling up to 4 external heating stages to be managed heaters. Facilitates control of a basic (electric heaters.etc.) heating system Compliance with Russian Compliance with Russian regulations regulations Coating which uses a conversion process to alter the aluminium Protect2 coating which doubles the Protect2 anti-corrosion surface into a coating which forms an integral part of the coil. corrosion resistance offered by protection for micro-channel Complete immersion in a bath to ensure 100% coverage. micro-channel coils, recommended for use coils No thermal transfer variation, tested to withstand more than in moderately corrosive environments 4000 hours of salt spray as per ASTM B117 Flexible, durable polyepoxide coating applied using an electroplating process to give micro-channel coils an anti-UV Protect4 coating gives a fourfold increase Protect4 anti-corrosion top layer. Minimal variation in the thermal transfer, tested to in the corrosion resistance offered by protection for micro-channel withstand more than 6000 hours of constant neutral salt spray micro-channel coils, recommended for use coils as per ASTM B117, improved impact resistance as per in corrosive environments ASTM D2794 Water heat exchanger Water heat exchanger inlet/outlet connection sleeves, Allows unit connection to a screw connection sleeves, screw screw connection connector connection Allows the unit to be installed in a Fan frequency inverter compliant with IEC 61800-3 class C1 residential environment, by reducing frequency inverter electromagnetic disturbance Pump frequency inverter compliant with IEC 61800-3 class C1 Allows the unit to be installed in a residential environment, by reducing electromagnetic disturbance Easy, quick installation (ready to use), and closed circuit protection of hydraulic systems to counter excessive pressure Prevents compressor short cycling and provides stability of the water in the loop Isolates the unit from the building, preventing vibrations and noise from being transmission to the building. Must be used the water side Easy to install. Limits the transmission of vibrations to the water network Prevents fouling in the water network Setpoint adjustable via 4-20 mA signal Free cooling mode drycooler management Connections enabling a 4-20 mA signal input Control and connections for an Opera or Vextra drycooler in free cooling mode equipped with the FC optional control unit the setpoint to be set by a 4-20 mA external signal control capacities to enable the drycooler to be used in free cooling mode
