The last thing which you want to do is to sit in front of a wall air conditioner and wait for your room to cool when you are suffering in heat waves. Being greeted with a uniformly cooled and dehumidified house is what you dream of when you come back home from the office. To generate the cool air from a compressor/condensing unit which sits outside of your home connected to an indoor fan coil unit which is located within the roof cavity of the house is what the mechanism of ducted air conditioners are.
In Sydney household and offices, ducted air conditioners are among the most common type of central cooling and heating which is used. When it comes to cooling and heating, the ducted air conditioning Sydney is the ultimate. To operate, more energy efficient and offering cheaper running costs than the other systems and are also generally clean and quiet.
In knowing how to operate a ducted system, the following are the points which you can follow:
- Ensuring that all external doors are shut and curtain/blinds on windows are drawn before operating your air conditioner in any mode. To improve the efficiency this helps to reduce the heat load.
- Close the door to the room and switch off the zone to that area if you have rooms which do not require air conditioning. This will reduce your cooling/heating costs and will also reduce the area that the air conditioner has to cool.
- Inverter ducted units should be set and left to run for the best results. They will ramp down and maintain that temperature to stabilize since the heat energy is stored in all the walls/floor finishes and fittings once obtaining the set temperature.
Operating your air conditioner in the summer
- On the thermostat, select “COOL” mode of operation.
- As the suggested temperature is between 24 and 26 degrees C, you need to set the thermostat temperature control to the “DESIRED TEMPERATURE”
- Fan operation to be set on high.
- For the zones to be conditioned setting the zone switches to the zone.
Until the air cools down to the temperature which is set by the thermostat, the air conditioning system will now operate on COOLING.
The fan will continue to circulate conditioned air when the set temperature has been reached and COOLING will stop.
COOLING will automatically commence and continue until the set temperature has been reached when the temperature rises above the thermostat setting.
Operating your air conditioner in the winter
- On the thermostat, select “HEAT” mode of operation.
- As the suggested temperature is between 21 and 24 degrees C, you need to set the thermostat temperature control to the “DESIRED TEMPERATURE”
- Fan operation to be set on low.
- For the zones to be conditioned setting the zone switches to the zone.
Until the air passing the thermostat rises to the temperature which is set by the thermostat control, the air conditioning system will not operate on HEATING and will continue to HEAT. Both HEATING and FAN will stop operating and will remain out of operation until the temperature at the thermostat commences to fail when the control temperature has been reached. To avoid circulating the air that is not being heated, which may be sensed as cool air and cause discomfort, the FAN remains out of operation.
Winter Cycle Defrost
The unit may go onto a defrost cycle in the winter months when the outside temperature drops below 7 degrees. The system will stop heating for several minutes as it will blow cold air during that period during defrost. On the wall controller, this is indicated by a flashing 3 point symbol.
When the system is allowed to cycle off as it should be, the need for defrosting is reduced.
Follow these operating procedures to minimize the need for defrosting:
- For economical and comfortable conditions set your thermostat correctly. 21 to 24 degree Celsius is what is suggested.
- Don’t keep your thermostat too high. You will not be allowing your system to cycle off and this will increase the likelihood of frost foaming by setting the thermostat too high.
- From the unheated rooms, close the doors. Causing the system not to cycle off enough, this will result in the thermostat being influenced by the cold air from the unheated rooms. As the thermostat is set too high the same problem lies.
- Allow the system to complete the defrost cycle.
- If it is defrosting, don’t turn the system off. Reducing the efficiency and increasing the running costs this will make the problem worse.
