Modern design

terneo srz thermostat is characterized by a unique minimalistic design. Its compact size, touch buttons and white display screen will be an elegant addition to any interior.

Useful functions

Calculate the power consumption of your equipment using the built-in load time counter!

You can also set the switch-on time delay from 0.5 to 99 hours. This allows you to start heating exactly when you need, while saving on electricity, and not on comfort.

Easy operation

The thermostat is adjusted using touch buttons. They have a spectacular appearance and serve longer. Digital screen makes it easier to navigate the menu.

Temperature measurement accuracy

Temperature sensor is located on the thermostat housing. You can adjust the value of the displayed temperature according to thermostat location and internal heating.

Simple installation

To start work, just insert the thermostat into the socket. The heating device is connected to the thermostat accordingly.

Safety and reliability in use

You can lock the control buttons so that you don't accidentally change the control settings. This is especially convenient when there are children at home or the device is installed in a public place.

The thermostat is equipped with thermal protection. If the temperature inside the housing rises above 80 ° C, heating will stop for safety reasons. Resumption of operation will occur after cooling the device to 60 ° С and pressing any of the buttons.

To increase the service life of the thermostat, the switching of the relay load is carried out as close as possible to the time when the voltage sinusoid passes through zero.
