PRODUCT DATA COMFORT 1200 BY NILAN Ventilation & passive heat recovery Commercial Passive heat recovery Ventilation < 1400 m3/h COMFORT 1200 The Comfort 1200 is a ventilation unit suitable for central ventilation of residential buildings, schools, offices and business facilities with a ventilation requirement of up to 1400 m3/h. Every component has been carefully selected with a view to unsurpassed quality and each component is tested throughout the entire production process, as are the finished units before leaving the factory. This quality control reflects our high standards, which not only exceed market requirements but also take them several steps further. Modulating bypass An automatic bypass valve directs the fresh air past the heat exchanger when waste heat recovery is not necessary, thus conserving energy. Automatic control The Comfort 1200 is supplied with an integrated CTS 602 control, which is operated by the enclosed control panel. The modern CTS 602 control communicates Modbus RTU RS485. A CTS system using this type of communication can easily be connected to the device. Filters The Comfort 1200 is supplied with bag filters. An M5 filter in the air exhaust and an F7 filter for fresh air are supplied as standard. The CTS 602 control has a built-in timer controlled alarm for change of filter. It is possible to install a pressure controlled filter monitor (accessorie). Doors The large doors allow easy access for the changing the filters, as well as for servicing of the unit. Frost protection An electric heater can be purchased for frost protection. This prevents the formation of ice in the counterflow heat exchanger in the event of long periods of frost. 2 COMFORT 1200 BY NILAN Counterflow heat exchanger Heat recovery is achieved by two counter flow heat exchangers made of highly corrosion resistant marine aluminium. The counterflow heat exchangers have an energy efficiency of more than 80% and prevent odours being transferred from the extracted air to the supply air. The CTS 602 control allows for cooling recovery. Plug fans The two fan sections consist of energy-efficient EC motors with built-in motor controllers operated by a 0-10V signal. The efficient fan wheels haverear facing impellers and are extremely quiet. Construction The Comfort 1200 is housed in a strong frame structure of Aluzinc with 50 mm insulation. Base The Comfort 1200 is delivered with a robust, built-in base. Heating elements External water or electric heating elements, regulated by the CTS 602 control, can be purchased. Pressure control The extraction and/or supply fan can be operated with the aid of a pressure transmitter. The water-heating surface can be built into the unit. 3 COMFORT 1200 Technical specifications Dimensions (W x D x H) 1815 x 825 x 970 mm Weight 230 kg Min. Airvolume 400 m3/h Max.

The operating panel must be placed in a dry, frost-free location, at least 1.5 m above floor level and at least 0.5 m from any corner. Avoid placing the panel on an external wall or in areas in direct sunlight. Operating instructions for the CTS 602 can be found in a separate user manual supplied with the unit. External communication The CTS 602 control unit communicates by default with Modbus RTU RS485 communication. A CTS system using this form of communication can easily be connected to the unit. Nilan units have an open Modbus communication, i.e. not only can the unit be monitored, but its operation can also be set in the same way as it can via the operating panel. CTS / Computer Konverter Modbus The protocol is set up by default for a Modbus RTU 30 address, but can be set to a value between 1 and 247. A Modbus converter allows you to connect one or more units to a computer to monitor and control the unit. 10 COMFORT 1200 BY NILAN Functional overview + Standard - Accessories 3 levels The control function is divided into 3 levels: User/Service/Factory with various options at each level + Weekly plan There is an option for you to set your own weekly programme. + User option 1 This allows you to override the operating mode in the main menu via an external potential-free contact or PIR sensor. + Alarms Alarm log featuring the last 16 alarms. + Filter monitor Filter monitor with timer (factory setting of 90 days).

Temperature efficiency The extracted air condenses when it is cooled down during heat recovery. The high temperature efficiency will slowly turn the condensate to ice, which will block up the counterflow heat exchanger unless action is taken to remedy this. With pre-heater tAußen > -3°C tAußen < -3°C Defrost function Operation Ice building In homes which are occupied at night, it would be advisable to protect the unit against frost when the outdoor temperature is coldest by using a pre-heating element. On the other hand, if the ventilation is for an office, it may be acceptable to decrease the operating level at night. Defrost Ice building Defrost The energy used for the preheating is not wasted, as it ensures a constant high temperature efficiency Frost protection No Normal operation After 30 min.

Pressure transmitter The extraction and/or supply fan can be operated with the aid of one or two pressure transmitters. Water heating element incl. regulation The supply temperature can always be raised to the required level using a water heating element. The water heating element is designed to be built into the unit and must be connected to the primary heating supply. Supplied with two-way adjustment valve, temperature sensor and frost thermostat. Electrical heating surface incl. regulation When you fit an electrical heating surface, you can raise the fresh air temperature to the desired level at any time. The electrical heating surface is supplied ready to fit into the fresh air duct and, for easy fitting, the device is pre-fitted with all the required sensors. Electrical pre-heating element (Frost protection) An electrical pre-heating element heats up the outdoor air before it enters the unit. This avoids having to defrost the unit, resulting in a loss of power. There are temperature sensors supplied to be fitted in the ducts. Expansion PCB The expansion PCB provides additional functions for the CTS 602 control unit, e.g., controlling the EM-box (see list of functions on page 7). Installationset Vibration absorbers and a water trap for the condensation outlet. Heating cable To protect the condensation outlet against frost, a 3 metre-long self-regulating heating cable can be ordered. 14 DELIVERY AND HANDLING COMFORT 1200 BY NILAN Ø 315 414 Transport and storage Comfort 1200 comes in factory packaging that protects it during transport and storage.
