Ouman Optiflexiot is a product developed for the energy optimisation of electrically heated buildings. The device uses smart and advanced algorithms to generate forecasts of future heating demands based on spot prices of electricity and weather forecasts. Forecasts help choose the most affordable hours for heating to make significant savings in heating costs. If necessary, heat is stored during the cheapest hours so that no heating is required during the most expensive hours.
The device can simultaneously control four different electrical loads independently of each other. You can select separate control methods for each:
> Cheapest hours on demand
> Hours cheaper than the average price
> Fixed price limit, cheaper hours
> PWM control by price
