The regulating range is between 22 °C and 26 °C. It can be increased or decreased by 1 °C with buttons /. The fan speed cannot be changed. MODE Cooling mode In cooling mode, the air in the room is cooled down to the adjusted nominal temperature. The desired room temperature is set with buttons / in 1 °C increments.
REMKO ATY DEHUMIDIFICATION mode In the dehumidification mode, the room temperature can be adjusted between 18 °C and 30 °C. Due to the low temperature of the refrigerant, the dew point of the air on the condenser is lower. The excess moisture in the air is condensed on the condenser, the room is dehumidified. The fan speed cannot be changed. MODE FAN button The fan speed can be adjusted with this button. A selection can be made between low, medium, high and automatic fan speed.
SLEEP button (covered) With the button a programming function is activated, which causes the nominal temperature in the cooling mode to increase after one hour by 1 °C and after 2 hours by 2 °C . In the heating mode, the nominal temperature is decreased after one hour by 1 °C and after 2 hours by 2 °C.
REMKO ATY Programming TIMER OFF TIMER Unit out of operation Programming TIMER ON/OFF SET Programmed time reached The regulation turns the unit on or off after programming. In operation, all settings are visible on the display. Out of operation, only the timer settings are visible. Unit On Unit Off Example: The regulation turns on at 9:00. The unit is in operation until 16:30. TIMER OFF (Covered) This button is used to program a decremental turn off timer.
I FEEL button (covered) The unit determines the actual temperature inside the wall unit. The temperature near the remote control may deviate from that setting. With the button, the temperature measured on the remote control is transmitted to the wall unit, the nominal temperature does not change. A continuing temperature reconciliation with the actual current temperature of the remote control is made approx. every 5 minutes as long as the function is turned on.
REMKO ATY Taking the unit out of operation Care and maintenance Time-limited shut down Regular care and maintenance ensure problem-free operation and long service life of the unit. 1. Let the interior unit run for 2 to 3 hours in air circulation mode or in cooling operation at maximum temperature setting to remove any residual moisture from the unit. 2. Take the unit out of operation with the remote control. 3. Turn the power supply of the unit off. 4.

REMKO ATY Installation instructions for technicians Important notes before installation NOTE The assembly and installation of the units and components may only be carried out by especially trained technicians. ■ Locate the unit in original packaging as close as possible to the installation point to avoid transport damage. ■ Check the contents of the packaging for completeness and check the unit for visible transport damage. Report any damage immediately to your contracting party and the shipping company.
Wall openings ■ A wall opening of at least 70 mm diameter and 10 mm slope from the inside to the outside must be made for each interior unit. ■ We recommend to pad the hole inside or to cover it for example with a PVC pipe to avoid damage to the lines. ■ After installation, the wall opening should be closed off on the building side with a suitable sealant.
REMKO ATY Set up inside a building ■ Make sure there is sufficient heat discharge, if the exterior unit is set up in the basement, the attic, in secondary rooms or hallways (Fig. 7). ■ Install an additional fan with the same air volume flow as the exterior unit installed in the room, which can compensate for any possible additional pressure losses through air channels (Fig. 7). Ensure a continuing unimpaired air supply from outside, if possible through opposite, sufficiently large air openings (Fig. 7).
Installation Oil return measures NOTE If the exterior unit is located at a higher level than the interior unit, then suitable oil return measures must be made. This is usually done by fabricating an oil lift fitting, which is to be installed for each 2.5 ascending meter. max. 5 m exterior unit 3. Remove the front of the unit by lifting the front in the lower area from the body approx. 10 cm and folding it upward (Fig. 10). 10 Release the unit front 11 Pull off the plug 4.
REMKO ATY Connection of refrigerant lines The on site connection of the refrigerant lines is made inside the unit. If necessary, a reducer or expansion fitting must be installed on the interior units. These fittings are part of the accessory kit provided with the interior unit. After assembly, the connections must be insulated impervious to vapor diffusion. CAUTION The units have been filled at the factory with dry nitrogen to check for leaks.
Leakage test 12 Deburring the refrigerant line Refrigerant line When all connections are made, the pressure gauge station is connected to the corresponding Schrader valve connections, if present: red Deburrer 13 = small valve = Injection pressure blue = large valve = Suction pressure Flanging the refrigerant line Flanging tool After completed connection, the leakage test is carried out with dry nitrogen.
REMKO ATY Condensation connection Electrical connection Due to the dew point shortfall on the evaporator, condensation is created on the interior unit during the cooling operation and on the exterior unit during the heating operation. Below the evaporator is a catch pan, which must be connected with a drain. ■ ■ ■ ■ 11 The building side condensation line must be routed at a down slope of min. 2 % (Fig. 11). If necessary, prepare a vapor proof insulation.
