Comparison Vaillant sensoHOME VRT 380f vs Vaillant sensoHOME VRT 380

How to connect the controller to the controlled device.

— Wired. Connecting with wires is the most common option. It is due to its main advantages — simplicity, reliability and low cost. On the other hand, the wiring itself can be quite troublesome and time-consuming.

— Wireless. Wireless connection — usually by radio channel. To do this, the kit usually provides an external transceiver connected to the controlled device. The main advantage of wireless models is obvious — they are much easier to install because no need to run extra wires. On the other hand, such a technique is much more expensive than wired, and communication has a limited range, which is further reduced if there are obstacles (such as thick walls) in the signal path.

— DIN rail. The phrase "on a DIN rail" traditionally refers to the method of installing the device (see "Mounting"); the connection is usually carried out by wire. However, this option is taken out separately for the reason that DIN devices are standardly mounted in a distribution cabinet — unlike conventional wired thermostats, installed directly in the room. However, sometimes it is an advantage: the distribution cabinet can be locked with a key, restricting unauthorized access to the thermostat. Models with such a connection usually refer to professional equipment used in industrial...facilities, warehouses, etc.
