Frequently Asked Questions

• How exactly does a manual (simple) thermostat work? It measures the temperature at its installation location and, when it drops below the set value, closes a contact that switches on the heat source (boiler, pump, radiator) - once the set temperature is reached, the contact opens again. Unlike programmable thermostats, it has no weekly or daily schedule; the temperature is set manually using a rotary or slide control.
• Where should the thermostat be placed? In a location that best represents the room's typical temperature - away from direct sunlight, draughts, radiators, or other heat/cold sources that could distort the measurement.
• Must installation be carried out by an electrician? Connecting the thermostat to the electrical circuit of the heating source should be done by a person with electrical qualification, as it involves working on the electrical installation and switching a load.
