Would you like to be able to operate your patio heater remotely? Then you need a dimmer. If you want to install your terrace heater in the ceiling, for example the Solamagic 2000 Eco + ceiling installation, then you need an external dimmer because otherwise there is too little space. This dimmer must then have sufficient power. For example, you can choose the Solagmagic Somfy Dimmer External. Attention! A dimmer should never be placed with insufficient wattage, because there is a fire risk. If an external dimmer is connected to the patio heater, it can be operated by means of a remote control. If you want to operate multiple patio heaters with one remote control, you can choose a 5-channel remote control. This is a remote control to which a maximum of five channels / patio heaters can be connected. For example the Somfy 5-channel remote control (scroll). Incidentally, you can connect several patio heaters to one group. Then check with an installer if the group can handle it, otherwise the residual current device will always fire out. It is best to choose a fuse of 16A or 20A (depending on the load).
