High wall-mounted an coil units FM 2 4 kW New Galletti hydronic indoor unit which combines quiet operation, a refined design and comfort control FM stands out for its advanced technological features, including a BLDC motor, incorporated adjustment valve and serial communication. Automatic control of the fan speed is managed through a proportional, integrative and derivative logic capable of ensuring stability, precision and rapid intervention, respectively. The serial communication enables the interaction of up to 32 units, thus guaranteeing a global management with automatic adjustment of the parameters on all units coordinated from a single point. With the WALLPAD accessory it is possible to control the units connected in the system one by one. FM can be interconnected with a supervision system with Modbus communication. On the one hand the valve already installed on the unit and the system of hoses permits fast, safe installation, and on the other hand the BLDC fan motor technology and coil providing an optimized heat exchange offer the user a quiet, high-performance, energy efficient indoor unit. BLDC motor High wall mounting Infrared remote controller Electronically controlled BLDC motor Compact dimensions, identical or the whole range Incorporated 2- or 3- way ON OFF valves PID regulation Construction o global addressable networks with an external supervisor 23/33/43 models These models are characterized by the presence of a 3-way valve installed on the unit which allows it to be integrated into any type of installation, in particular in the presence of ON OFF pumps. 22/32/42 models The models with a 2-way valve already installed on them can be perfectly adapted to systems which include a modulating circulator or another means for varying the water flow.

MAIN COMPONENTS Heat exchanger Valve assembly The nned block heat exchangers consist o copper tubing and aluminium ns. The hydrophilic treatment on the ns assures an optimal heat exchange even in the presence o sur ace condensation. Two- or three-way ON/OFF valves already wired and installed inside the indoor unit. The connection to the system is made with hoses located on the rear o the unit. Without any increase in dimensions or complications in installation, the valve closes on reaching the set point, recirculating the ow o water and preventing it rom entering the heat exchanger.
