You can turn on or turn off your air conditioning system remotely with iSocket only if your appliance has a plug. Most air conditioning systems are wired directly to an electric cabinet and have a remote controller to regulate the temperature. You cannot connect the remote controller of such an appliance to iSocket, but if the equipment has a plug you can connect this plug to the iSocket, and set up your air conditioning system to the desired temperature and shut it down (turn off the power supplied through the iSocket to the plug of the appliance). You can then switch it on remotely before arrival. Please note, this option might not be recommended by the manufacturer of the equipment. You do this at your own risk.
