The programmed settings and parameters are shown on the display before the unit switches off. POWER TEMP button The TEMP button is used to set the desired target temperature in 1 °C steps. This setting is not supported in FAN circulation mode.
Press the MODE button to change to another mode. A total of 5 modes are available: MODE button 1. AUTO 2. COOL 3. DRY 4. FAN 5. HEAT MODE Automatic mode, automatic selection of cooling or heating mode Cooling mode, mainly used in summer Dehumidifying mode, used in summer or winter Circulation mode, no cooling or heating output Heating mode, mainly used in winter MODE MODE MODE Press the MODE button once or repeatedly to switch to automatic mode.
REMKO SV Mode Dry Press the MODE button once or repeatedly to switch to dehumidifying mode. Use this mode to dehumidify the room in an unregulated fashion. After pressing the DRY button, select the desired temperature and fin position. It is not possible to set the fan speed. The fan is switched off at certain intervals to lower the temperature at the cooling battery. The low temperature causes the air temperature at the fins to fall below the dew point.
Mode heat Press the MODE button once or repeatedly to switch to heating mode. Use this mode to heat the room air to the desired target temperature. The fan will only start when the fin temperature reaches 38°C. Press the TEMP / buttons to set the desired room temperature in 1 °C steps. If the room temperature falls 1 °C below the set target temperature, heating mode is activated. f the actual temperature rises approx. 1 °C above the set room temperature, the controller switches the heating off.
REMKO SV TIME buttons Switch-on time The TIME-ON/-OFF buttons are used to program the switch-on/off time, the TIME-SET button to set the time. Press the TIME-ON or TIME-OFF button to activate the timer. The clock display then disappears. The timer symbol for the switch-on/off time will flash. Press the TIME-SET button to set the desired switch-on/off time in 10 minute steps. Switch-off time After programming has been completed, the settings are transmitted to the indoor unit.
Shutdown Care and maintenance Temporary shutdown Regular care and maintenance ensure trouble-free operation and a long service life. 1. Let the indoor unit run for 2 to 3 hours in circulation mode, or in cooling mode at maximum temperature, to extract any residual humidity from the unit. 2. Shut down the unit using the remote control. CAUTION Prior to performing any work, ensure the equipment is isolated from the voltage supply and secured to prevent accidental switch-on! 3.
REMKO SV Cleaning the cover on the indoor unit 1. Disconnect the supply voltage to the equipment. 2. Open and fold down the air inlet guard on the cover. The filter is held in place by the flaps screwed in at the side of the guard(Fig 1). 3. Clean the guard using a soft, damp cloth. 4. Switch the supply voltage back on. 5. Any dirt can be cleaned off using lukewarm water and mild cleaning agents (Fig 4). The dirty side should be face down. 6.

Installation instructions for qualified personnel Important points prior to installation ■ Transport the unit in its original packaging as close as possible to the installation location.This avoids transportation damage. ■ Check that the packaged contents are complete and inspect the unit for any visible signs of transportation damage. Immediately notify any deficiencies to the contractual partner and forwarding agent.
REMKO SV Installation material Rain Snow The indoor unit is fastened using 4 threaded rods (provided by the customer). The unit should be at least 10 cm off the ground when mounted on the roof or ground. An optional floor bracket is available as an accessory. The unit should be wall-mounted in areas of heavy snowfall.
Installation inside buildings ■ Ensure there is adequate heat dissipation when placing the outdoor component in cellars, attics, adjoining rooms or halls (Fig 5). ■ Install an additional fan with a rated flow comparative to that of the outdoor component being installed in the room. This is used in conjunction with ventilation ducts to compensate any pressure losses (Fig 5).
REMKO SV Installation Installation should only be performed by authorised specialists. Installing the unit The indoor unit is mounted face down on four threaded rods. Take into account the ceiling grid and any other installations. 1. Use the dimensions of the ceiling cassette (Fig 8) to mark the fixing points for the threaded rods on structural parts approved to support the static load above the suspended ceiling. 2.
2. Remove the factory-fitted protective caps and union nuts on the connections. These should be used during installation. 3. Before flanging the refrigerant pipes, ensure that the union nut is fitted on the pipe. 4. Prepare the laid refrigerant pipes as shown below (Figs 11+12). 5. Verify that the shape of the flange is correct (Fig 13). 6. First connect and hand-tighten the refrigerant connections to ensure they are correctly seated. 7.
