Our FYTO SWITCH thermostats gonna "regulate" it for you. The FYTO SWITCH Classic marks the start of our series of thermostats and stands out because of its elegance, reliability and his intuitive handling. The two-way regulation enables both automated control of cooling components (e.g. a fan) as well as warming ones (e.g. the FYTO HEAT Deluxe heating mat). This makes the FYTO SWITCH Classic the ideal companion for temperature regulation of indoor greenhouses, grow boxes or other environments
