Vesta. Roman goddess of the sacred fire and family hearth. Saying "warmth of home" evokes a pleasant feeling of security and safety even today. That is why our vesta is here. So you can enjoy life with your family and pay only for the heat that you have really consumed.

description

vesta is two-sensor electronic heat cost allocator for determination of the consumption of room heating radiators. Simply stated – consumption value is calculated based on temperature of the radiator and room temperature. It allows to determine radiator contribution to the heat consumed in your building and to calculate payment for the heating in accordance with local legislation.

communication

Required data including various statistical items (history) can be obtained in any moment thanks to two-way radio communication. If necessary, you can also remotely change the settings (e.g. the beginning and the length of the measuring period or rating factors) without annoying entering the apartment and reprogramming with special device. All communication is of course coded in accordance with modern trends in the field of radio communications. So your data are safe with us.

displayed data

Each user can check measured data for the current and previous measuring period on the allocator display. But as we know that the demands of various householders may vary, we enable our partners to define the items displayed on the LCD according to their needs.

benefits

  • easy installation, regardless on distance between welded studs on panel radiators
  • possible personalization thanks to easy programming
  • remote reading of any historical values makes resolving of potential disputes easier
  • readings and configuration with the radio reading unit hermes without entering the apartment
