What should I do before connecting the chronothermostat to ensure safety?
Before connecting the chronothermostat, make sure that the load (pumps, valves, boiler, etc.) are not powered-up and are within the rating of the contact. The installation and assembly of electrical equipment must be performed by expert personnel.
