Mounting, removing and wiring of control panel The control panel is wired straight from the electrical connection box. The control panel can also be connected in series with a CO2 sensor or another control panel. (See External electrical connections on page 11.)

Panel address Control panel addresses 1 If two or more control panels are connected to the system, the addresses of the control panels need to be changed. E.g. 3 control panels Panel address • Connect the first control panel to the unit and change its address to 3. 1 • Connect the second control panel to the unit and change its address to 2. • Connect the third control panel and make sure that its address is 1. If control panels have the same address, they go to bus fault state. In this case, remove one of the control panels and change the address of the other panel. The above mentioned situation can arise in connection with the later installation of an additional control panel.

Connecting two or more units (slave unit)

• Connect slave units as specified in the adjoining connection instructions. Slave units do notoperate independently, but follow the instructions received from the HOST UNIT TERMINAL BLOCKSLAVE UNIT TERMINAL BLOCK SLAVE UNIT TERMINAL BLOCK SLAVE UNIT TERMINAL BLOCK host unit. Neither control panel nor sensors must be connected to a slave unit. NOTE! + wire must not be connected to a SLAVE UNIT. SLAVE UNIT must not have a 6K8 resistor in place.

Filtering Efficient filtering of outdoor air (G3 + F7) prevents harmful particles from entering the ductwork and rooms via the unit. Good filtering of extract air (G3) diminishes the contamination of the unit and ensures efficient heat recovery and extract air fan operation. Clogging of the supply / extract air filters and of the ductwork can be monitored by equipping the unit with a pressure difference switch. Heat recovery and heating With efficient heat recovery, most of the heat of contaminated extract air can be transmitted to outdoor air coming inside. The efficiency of the heat recovery cell is circa 80%. If outdoor air does not get sufficiently warm in the heat recovery cells, it can be heated with a water or electric post-heating unit (optional). The unit features an automatic heat recovery bypass function, which eliminates needless heating of outdoor air during summer. The unit also has a water post-heating unit with an automatic defrost function. Defrost The automatic defrosting of the heat recovery cells intermittently stops the supply air fans when the temperature of exhaust air goes under the set threshold value. In order to minimise momentary stoppages of the supply air fans the fan is also equipped with an electric preheating unit.

DESCRIPTION OF OPERATION / Electric post-heating unit Control of operation Heat recovery defrosting If needed, power supply to the unit can be controlled via a contactor in The control centre of the unit controls the operation of the preheating unit the distribution panel with a timer program, for instance. After starting, LP1 on the basis of the measurement data of the temperature sensor TE1, the unit first operates at minimum capacity. After that, capacity is preventing freezing alerts and the stopping of the supply air fan SF. If the adjusted on the basis of the measurement data given by the air quality capacity of the preheating unit LP1 is not sufficient, the control centre sensors, and/or through manual control on the control panel. keeps stopping the supply air fan SF on the basis of the measurement data on the temperature sensor TE1, thus preventing the heat recovery cell from Fan speed adjustment freezing.

INSTALLATION INSTRUCTIONS

A Location of the ventilation unit F • The unit is mounted indoors, in a place where temperature does not fall below +10°C. E B • The unit is to be mounted in a place where the sound pressure level coming through the envelope is not acoustically disturbing (storerooms, corridors, technical rooms, and in some cases rooms where people spend time). F • The unit is equipped with an adjustable base. If the unit is mounted on the wall, attention needs to be paid to the weight of the unit (146 kg) and to vibration isolation. • The unit is splash protected (IP34), and can thus also be mounted in a damp room. C Electrical connections D • The unit is permanently connected to the mains supply. The electrical connection box of the unit is located inside the unit adjacent to the connection outlet of the supply air ductwork. A • The cables connected to the unit are wired through the bushing seals and cable inserts equipped with cable clamps and located next to the connection outlet of Duct outlets the supply air ductwork. B Cable clamps with bushing seals (PK16) C Condensing water tank Installation D Socle • Remove the upper door of the unit (4 door screws). E Cover strip • Remove the cover of the electrical connection box (2 screws 3.5 x 9.5) • Mount and connect the needed cables to the screwed terminal block as specified in F Measurement outlets the connection instructions. • The external connection diagram is shown in these instructions and inside the cover of the electrical connection box. • The internal connection diagram is shown in these instructions and inside the cover of the electrical connection box. Channel outlets of the unit • The unit is equipped with four ø200 external connection outlets. Necessary connecting pieces (e.g. inner or bent connectors) can be attached to external connection outlets. NOTE! LENGTH OF THE CONNECTING HEAD OF THE CONNECTING PIECE NO MORE THAN 35 MM. Fix the ducts steadily and tightly to the relevant outlets. (NOTE! Unit models L/R). Implement duct insulation if needed as defined in the ventilation plan.

Air flow measurement outlets • The fixed air flow measurement outlets are located behind the cover strip. To remove the cover strip, open its straight-slot fixing screws. • Via the measurement outlets, the total pressure of the supply and extract air ductwork can be measured with a differential pressure instrument. Pressure readings and air volume tables (pp. 3 and 4) show volume flow rates at various adjustment positions. • The red measurement hose is on the pressure side and the black hose on the suction side of the fan.

NOTE! Water-circulating heating unit includes a control valve. Pressure difference switches If the unit is equipped with pressure difference switches monitoring the pressure difference between the supply and extract air ducts, they have to be set at their correct values after the installation and adjustment of the ductwork and the related terminal units (valves, outdoor grilles etc.). For more detailed information on adjustments, see the instructions for using the unit.

Condensing water connections • Water condensing from extract air going through the unit can be removed from the bottom tank in two ways. • When the humidity content of extract air is high, as for example in washing rooms, the condensing water is led from the screw-type coupling in the bottom tank to the floor drain via the condensing water outlet (water seal) delivered with the unit. Any pipe connected to the condensing water outlet must not rise. • When the humidity content of extract air is low, as in office rooms, the condensing water can be led from the screw-type coupling in the bottom tank to the condensing water tank delivered with the unit. It is pushed below the bottom tank to the guide posts in the base. In this case, no separate condensing water outlet is used. NOTE! When a condensing water tank is used, it has to be inspected sufficiently often. • The screw-type coupling is located almost in the middle of the unit. This is why the unit has to be mounted level with the horizontal. Location of condensing water connection
