Seltron ST1B Digital Room Thermostats

Presentation

ST is the new generation of modern room thermostats. They are used for the control of room temperature in smaller houses or for the zone control of room temperature in larger residential facilities. In addition to the room temperature, it also measures the relative air humidity and pressure.

Typical application

• Radiator or convector heating.
• Floor heating (low-temperature control of the supply temperature must be ensured).
• Wall or ceiling heating or cooling.
• Electric floor heating.

Features

• Up to 5 preset applications.
• 2 preset time programmes.
• Simple use and setup.
• Display of the measured and desired temperature.
• PARTY, ECO and HOLIDAY user functions.
• Weekly program timer for time programmes.
• Automatic switchover between winter and summer time.
• No new setup required in the event of power failure.
• Measurement of relative air humidity, air pressure, weather forecast display.
• Simple installation and connection.

Outlined functions

Large backlit display
The ST room thermostats feature a large display that allows the users to read the information from a distance. The ST model is equipped with a light sensor for an optimum visibility, with the help of which the illumination of the display is adapted to the light in the room.

Preset time programmes
ST room thermostats provide the selection between two preset time programmes. The user is able to create the time programmes according to their wishes, or they may use to preset time programmes and adapt them if necessary.

PARTY, ECO, HOLIDAY user functions
The thermostat is equipped with quick buttons through which we enter user functions directly, such as PARTY , ECO and HOLIDAY. By choosing the PARTY function, the daytime room heating is prolonged.
By choosing the ECO function, the heating temperature reduces for a certain period of time.
In the holiday operation mode, we set the heating temperature during our prolonged absence.

Measurement of relative air humidity, air pressure, weather forecast display
ST measures the air humidity and pressure in the room. Based on the air pressure, also the weather forecast is possible.

Installation options
Battery powered room thermostats or thermostats with a standard electrical connection are available. They can be installed into a pre-prepared flush mounted socket or on the wall.
