They are reversible and can be used for heating and for cooling in summer. They can also be equipped with an optional «insulation kit» for air conditioning using fan coil units. They are composed of an outdoor «Inverter» unit, which is connected to the inside module by cooling connections. The indoor module comes fully equipped and includes, in particular: • DIEMATIC Evolution control panel with control system that can be programmed according to the outside temperature that communicates with the outdoor unit and, depending on the options connected, can be used to manage up to 3 heating circuits, direct or with mixing valves and a domestic hot water production circuit. Option of connecting HPI heat pumps and boilers with DIEMATIC Evolution control system in cascade; • High energy efficiency pumps (EEI < 0.23); • Hydraulic filter with isolating valve. This module is available in 2 versions: • MIT-S /E for auxiliary heating by integrated electrical heater, which can be wired as either 2 or 6 kW single-phase, 4 or 12 kW three-phase (cannot be installed without the heat pump) • MIT-S /H for auxiliary heatin

PRESENTATION OF THE RANGE The HPI S range of air/water Inverter heat pumps comes in models of 4.6 to 24.4kW (heating output at +7/+35°C in accordance with the EN 14511-2 standard). They comprise an outdoor unit and a MIT-S indoor unit. AWHP OUTDOOR MODULE TECHNICAL DATA The AWHP 4.5 MR to 27 TR outdoor modules are used in our current split air-to-water ranges. The outdoor module comprises: • a modulating compressor, an aluminium fin heat exchanger • 1 to 2 axial fan(s) (depending on the model) • a liquid separator and power reserve • a 4-way reversal valve • a HP pressure switch and a pressure...
