The significant increase in energy prices experienced in 2022, along with concerns about energy supply disruptions and procurement arrangements tied to daily market prices, have raised serious concerns among market participants.

Therefore, as operators (office, hotel, apartment), it is crucial to effectively monitor and control consumption at the building level. This is where our Waddletherm smart thermostat comes into play. Unlike units available in the market, it intervenes on the hot water utilization side, allowing for the creation of an online monitoring and control system with compatibility for FanCoil and other heating and cooling systems.
