to control heaters, air conditioners, fans, and similar equipment by comparing the current measurement with a reference temperature or programmed thresholds. Such controllers are used to maintain specific room temperatures, water temperatures in tanks, or temperatures of various objects. They can operate fully automatically or in cooperation with other components or adjustment elements operated by third parties( e. g. residents / employees adjusting thermostat settings).
Meters, Protection Devices and Accessories
The Zamel range also includes modules that facilitate supervision of the entire installation. These include energy meters and voltage indicators, essential components in many systems, especially those based on renewable energy sources such as photovoltaic installations or wind turbines.
Power limiters and protection modules are adjustable devices that perform a role similar to traditional fuses( i. e. circuit breakers), but with configurable parameters. Both the trip threshold and the automatic reset time can be adjusted. Such protective devices have numerous applications and help reduce installation downtime and maintenance time.

Other practical Zamel installation modules include useful solutions such as transformers( secondary voltage relative to mains voltage: 8V, 12V, or 14V), audible signaling devices( alarms with various functionalities), and DIN rail-mounted( TH35) switches that can be used, for example, to temporarily disconnect circuits without wearing out the contacts of a circuit breaker.

Building Automation
Most of the products presented above can be used as components of building automation systems, although they have a much broader range of potential applications. Zamel also offers highly specialized modules, such as stairwell timers designed for energyefficient lighting control in corridors and staircases, as
well as dimmers that allow the brightness of various light sources to be adjusted using wall-mounted switches.

Another building-specific installation component is the miniature shutter controller, which enables local or remote operation of window shutters( e. g. security shutters). Other compact automation components designed specifically for buildings include flush-mounted relays – offering functionality and parameters similar to DIN rail-mounted versions, while being easy to install within existing wiring during modernization projects.

The Zamel building automation range is complemented by twilight switches, typically used to control lighting based on ambient daylight intensity. However, the parameters of these switches also allow them to control other loads. Some models are mounted directly in sunlit locations, while others feature connections for externally installed probes, with the switch itself mounted inside the distribution board.
Sensors
The aforementioned light probes are just some of the many sensors available in the Zamel portfolio. The manufacturer supplies products designed to work with the automation components described above, including flood, motion, and temperature sensors. These accessories are intended for use with the supplier’ s modules, enabling both the expansion of existing installations and their maintenance and servicing.
