Помогите пжлста понять, в чем различие между:
Velda I-Tronic и Velda T-Flow Tronic

На сайте производителя это разные продукты:
http://www.velda.com/pond-products/a...lgae/i-tronic/
http://www.velda.com/pond-products/a...t-flow-tronic/

Кто-нибудь сталкивался ? Спс

UPDATE Ответ от производителя:

Dear Eugene,

thank you voor your message. The function of the device is the same in principle. The T-Flow Tronic is an advanced I-Tronic. These differ from the I-Tronic in the housing shape and its operation has been simplified. The biggest difference is that the T Flow Tronic is equipped with a temperature sensor, thereby switching off the appliance at a temperature of 12 ° C. or colder automatically.
