This kit includes everything required to connect the device to an already existing remote control seen in the picture. Requires that you have a remote control that can control your heater, and you can locate the receiver module and understand how to connect the unit according to the schematic below. The remote controllers in the picture is not included.
When the unit is connected this way, they work together, i.e. if you turn on with your phone, you can then turn off with the remote control and vice versa!
If you have the vehicle manufacturer's logo on the remote control or if it looks different from the ones in the picture, you need to send a picture of the receiver module so we can confirm that it works with your installation, which is not always the case when the heater and remote control are factory installed. The receiver module sits somewhere inside the car's cabin behind a panel or so. Sometimes you can try to follow the antenna. Contact us if you are unsure!
