Hoval TopTronic E

The Hoval TopTronic E (TTE) is an operating system for Hoval district heating, Air/Water, Brine/Water and Water/Water heat pumps, as well as gas, oil and wood heat sources, which can be used standalone or combined into hybrid systems for heating and cooling.
It can also operate a Hoval ventilation system.
In addition, the TopTronic E (TTE) can communicate with the Hoval PV-Heater.

This DDF defines the device’s inputs and outputs, provides visualization and error checking within the DEVICE system, and sets the ventilation mode to Constant.
