Page 4: General Information
General information Important information CAUTION Do not turn on the power supply for the unit until the hot-water tank and central heating circuit is filled with water. WARNING The electric boiler for the central heating must not be activated until the system has been filled with water and the cen- tral heating circuit has been vented. -
Page 5: Water Quality Requirements
Requirements to quality of water The hot water tank in the Nilan units is made of steel, which has been given a double enamelling, to ensure an extra long service life. In addition, the tank is equipped with a sacrificial anode as extra protection. It is important that the sacrificial anode is replaced regularly. -

The input signal must come from a potential-free switch. When closed, the function is activated with the settings selected in the control panel under Service / User selection. -
Page 15: Modbus
Modbus The CTS602 controller has an open Modbus RS485 communication, that allows you to communicate with it and control the ventilation unit via external control systems. We refer to the software manual and the Modbus protocol for further information about settings and registers. Connection via the 8-pin plug: Modbus is connected in following pins: 1. -
Page 16: External Heat Supply
External heat supply The unit can control an external heat supply, such as electric radiators or an underfloor heating system. This feature is used in the cases where the unit contributes to the heating of the house via a heat pump and/or a after-heating element. -

This is to avoid vibrations from the unit being transmitted to the duct system. It will also make it easier to move the unit, which may be necessary during future services of the unit. Nilan can supply Soundflex tubes that you can use as flexible connections between the ventilation unit and the duct system. They will also reduce sounds from the system considerably. -
Page 24: Extract Air
Extract air Install the extract air valves in high-humidity rooms and place them strategically where they can extract humid and vitiated air from the dwelling/building most efficiently. High-humidity rooms are, for example: • Bathroom • Lavatory • Kitchen • Utility room Supply air Install supply air valves in living areas. -
Page 25: Balancing
Balancing Important information ATTENTION To ensure the ventilation system operates optimally, it is important that it is balanced correctly. We recommend that ex- perts do this. It is important to measure the total supply air and the total extract air. The system must have a minimum vacuum, which means it draw out more air than it blows in. -
Page 26: Troubleshooting
Troubleshooting Emergency mode Emergency mode domestic hot water If an error occurs in the control system or components in the VP18 M2, and the unit therefore stops, it will not be able to produce do- mestic hot water. If the installer is not able to come right away or the error happens outside the opening hours, and you therefore cannot contact the in- staller, there is a possibility to get hot water by setting the unit into emergency mode. -
