The plug of the USB cord is pulled out of the board, the tulle in the shelf on the left side of the unit. after which it can be pulled through the tulle. ATTENTION! The T1 sensor, which is located in the shelf on the right side (together with the USB connector), must be pulled down through the tulle. -
Page 14: Electrical Installation
Electrical installation Safety ATTENTION All work must be carried out by qualified persons and in compliance with existing legislation and regulations. ATTENTION It is important that the power is off, if you do work to the electrical components of the unit. It is important to check that wires are not damaged or squeezed during connection and use. -
Page 15: Electrical Pre-Heating Element
Electrical pre-heating element If the unit is purchased as a Polar version, the electric preheating surface is mounted on top of or on the side of the unit in the outdoor air duct before the unit with the required temperature sensor. 1. -
Page 16: Connecting A Gateway
Connecting to the internet Using an RJ45 cable, you connect the gateway to a router with internet connection (cable not supplied by Nilan). Once the gateway is connected to a power supply and connection to the router has been established, you will have a secure cloud con- nection. -

(according to the wiring diagram), where the wires from the front-connection are removed. Nilan offers a connection cable with RJ12 plugs of 10 m and 20 m, respectively. It is also possible to customize a cable up to 50 m in length. -
Page 18: Electrical Connection Accessories
Electrical connection accessories User selection 1 User selection 1 is connected via the 8-pin plug mounted on top of the unit. The user selection functions are used to override normal operation. 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 19: External Electrical Pre-Heating Element
External electrical pre-heating element It is possible to purchase an external electrical pre-heating element for frost protection of the ventilation unit. The electrical pre-heating element is mounted in the outdoor air duct before the unit with the necessary temperature sensor. If it is desired to see the actual outdoor air temperature on the control panel, the temperature sensor T1 / T8 must be led out into the duct before the pre-heating element. -
Page 20: External Electrical Pre-Heating Element For Mounting On Top Or Side
External electrical pre-heating element for mounting on top or side If your ventilation unit is not a Polar version with an integral pre-heating element, it is possible to purchase an external electrical pre- heating element for frost protection of the ventilation unit. The electrical pre-heating element is mounted in the outdoor air duct on top or side before the unit with the necessary temperature sensor. -
Page 21: Electrical After-Heating Element
Electrical after-heating element An after-heating element is necessary if you want to control the supply air temperature. The electrical after-heating element can be purchased for installation in the supply air duct. The required sensor, Expansion PCB and connectors to the ventilation unit are included.. ATTENTION The T7 temperature sensor is mounted after the heating element. -
Page 22: Co2 Sensor
sensor If there is a large load change in the home / building, it is advantageous to install a CO2 sensor to control the air exchange. The CO2 sensor measures the CO2 level in the exhaust air, and regulates the ventilation level accordingly. The CO2 sensor is mounted in the unit as illustrated below: 1. - Page 23 7. Connects as shown in the electrical diagram below 8. Reinstall the counterflow heat exchanger. Remember to reinstall the T4 sensor. Mount cover plate again and afterwards front plate. Remember to reconnect RJ12 plug in control panel. For SW version 2.00x or less, the resistor must be mounted in series with a black signal cable For SW version 2.01x and above, do not mount a resistor.

5. Connect the wires up in accordance with the wiring diagram. ATTENTION The expansion PCB and the connections must be installed by a certified electrician. The expansion PCB is an accessory for the CTS602 circuit board. Nilan does not supply external components. -
Page 25: User Selection 2
User selection 2 With User selection 2, the same options are achieved as with User selection 1. In addition, you get the option of a relay output that can control e.g. a damper or whatever need one may have to control an external function. User selection 2 potential-free input is connected to TF13 and User selection 2 output is connected to relay R7 on the PCB board. -
Page 26: Dtbu (Damper Option)
DTBU (damper option) If it is desired to run the cooker hood over the ventilation system, it may in some cases be difficult to get enough air for the cooker hood. To solve that challenge, an EM-box solution can be used. However, if there is not enough space in the installation for an EM box, you can alternatively connect a DTBU damper in the duct system, which has the same function, except that it does not have a built-in dirt filter. -
Page 27: Joint Alarm
Joint alarm It may be difficult to notice alarms if the unit is located in a place where access is difficult or infrequent, and if the control panel is located in the same place. An external alarm indicator in the form of an electric bulb or an acoustic signal can be connected to the ventilation unit and announce when an alarm occurs. -

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 32: 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 33: 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. -

Emergency mode Emergency mode domestic hot water If an error occurs in the control system or components in the Compact S, 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. -
