Miscellaneous item 1 (Group 22) nManagement of an humidifier with proportional or on/off control. nEnergy meter for monitoring of the power consumption of the installation. nEnergy meter and calculation of the cooling and heating capacities. In addition to the energy meter, the unit incorporates mixing and supply enthalpic sensors with RS485 communication that enable cooling and heating capacities to be calculated. nRefrigerant leak detector (in ppm). This allows prompt identification of gas leaks, guaranteeing the safety of any people in the vicinity. This detector allows the number of periodic revisions to the unit to be reduced.
