AUTOMATIC MODE In automatic mode, the controller autonomously selects between heating and cooling operation when the unit is first turned on. A nominal temperature of 24 °C is preset. MODE Cooling MODE AUTOMATIC In cooling mode, the air in the room is cooled down to the set nominal temperature. The desired room temperature is set with the ▲/▼buttons in 1 °C increments. If the room temperature is 1 °C above the selected nominal temperature, the indoor unit starts to cool the air in the room.
REMKO ATY Heating MODE In the heating mode, you can heat the room in spring or fall. The desired room temperature is set with buttons / in 1 °C increments. If the room temperature is 1 °C below the selected nominal temperature, then the indoor unit starts to warm up the air in the room. If the adjusted room temperature is exceeded by approx. 0.5°C, then the controller turns the heater function off.
Dehumidification MODE In dehumidification mode, the room temperature cannot be set. Due to the low temperature of the refrigerant, the dew point of the air at the condenser is undercut. The excess moisture in the air is condensed on the condenser, the room is dehumidified. The fan has four speeds. Neither the ion generator nor turbo mode can be selected in this mode.
REMKO ATY SWING Button (covered) The oscillating function of the air discharge fins can be adjusted with this butto. This makes it possible to switch directly between a fixed position and the oscillating function. The air distribution in the room is improved using the swing function. SLEEP Button This button activates a programming function, which causes the nominal temperature in cooling mode to increase after one hour by 1°C and after two hours by 2 °C.
PROGRAMMINGTIMER ON The controller turns the unit on after programming. During operation, all settings can be seen on the display. Out of operation, only the timer settings are visible. Timer on PROGRAMMING TIMER OFF 30 sec. The controller turns the unit off after programming. During operation, all settings can be seen on the display.

REMKO ATY INDOOR UNIT DISPLAY SET TURBO C By pressing the "ION" button several times, the "ION" function, the "Turbo" function, or both can be set at the same time. Ion function The unit is equipped with an ion generator to generate negative ions. A high concentration of negative ions is found for example in mountains, near waterfalls and in forests and people perceive this inhaled air as "clean". Only a slight ion concentration is found in interior rooms.
Shutdown Care and maintenance Temporary Shutdown Regular care and maintenance serves to ensure trouble-free operation and long service life of the unit. 1. Allow the indoor unit to run for 2 to 3 hours in air circulation mode or in cooling mode at the maximum temperature setting in order to remove any residual moisture from the unit. 2. Shut down the unit using the remote control.

REMKO ATY Installation instructions for qualified personnel Important notes prior to installation NOTE The assembly and installation of the units and components may only be carried out by especially trained technicians. ■ Transport the unit in its original packaging as close as possible to the installation location. You avoid transport damages by doing so. ■ Check the contents of the packaging for completeness and check the unit for visible transport damage.
Wall openings Selection of the installation location Wind ■ A wall opening of at least 70 mm diameter and 10 mm slope from the inside to the outside must be made for each indoor unit. The indoor unit is designed for horizontal wall installation in the upper wall area (at least 1.75 m from the upper edge - floor). However, it can also be used in the upperwall area above doors. If the unit is being installed in windy areas, ensure that the warm outlet air discharges in the main wind direction.
REMKO ATY Installation inside buildings ■ Ensure that heat can dissipate adequately when placing the outdoor component in cellars, attics, adjoining rooms or halls (figure 7). ■ Install an additional fan with a rated flow comparative to that of the outdoor component being installed in the room.
Installation Oil return measures NOTE If the outdoor unit is installed at a higher level than the indoor unit, we recommend that suitable oil return measures are taken. Usually an oil pump bend is installed for every 2.5 metres of height difference. Outdoor component max. 5 m Oil pump bend in suction pipe to outdoor component 1 x every 2.5 metres of rise in the line Open display cover 9 Remove screws Installation may only be performed by authorised specialists.
REMKO ATY Connecting the refrigerant lines The on-site connection of the refrigerant lines is undertaken inside the unit. It may be necessary to fit a reducer or flared adapter to the indoor unit. These fittings are included with the indoor unit as an accessory kit. Once installed, the connections should be sealed to prevent vapour diffusion. CAUTION The units are factory filled with dry nitrogen to check for leaks. The pressurised nitrogen is released when the union nuts are loosened.
Monitoring for leaks 12 Deburring the refrigerant line Refrigerant line Once all the connections have been established, the pressure gauge station is attached as follows to the Schrader valve (if fitted): red Deburrer = small valve = injection pressure blue = large valve = suction pressure 13 Flanging the refrigerant line Flanging tool After completed connection, the leakage test is carried out with dry nitrogen.
REMKO ATY Condensate drain Due to the dew point shortfall on the vaporiser, condensation is created on the indoor unit during the cooling operation and on the outdoor unit during the heating operation. Below the vaporiser is a collection tray, which must be connected to a drain. ■ The condensation line is to be installed with a minimum slope of 2 %. (figure 11). If necessary, fit vapour diffusion tight insulation. ■ Lead the condensation line freely to the run-off line.
Connecting the outdoor component Connecting the indoor unit Figure 17 Proceed as follows to connect the cable: 1. Remove the cover from the unit. 2. Remove the side panel next to the terminals. Terminal bar / control bar 3. Feed the cables through the ferrite core supplied in the delivery (figure 17+18). Mains cable Figure 18 4. Feed the cable through the edge protection ring of the fixed connection plate. 5. Connect the cable as shown on the electrical connection diagram. 6.
