To reset the AERMEC VMF-E5 to auto mode for fan coils:
1. Press the C key to enter modification mode. 2. Press the B key to highlight the current setting. 3. Use the A or B key to change the setting to ON (this enables automatic changeover based on the thermostat). 4. Press the C key to confirm the new setting.
This enables the automatic changeover function, allowing the system to switch between heating and cooling based on detected temperature.

The appliance warranty does not cover the costs for ladder trucks, scaffolding or other elevation systems that may become necessary for carrying out servicing under warranty. AERMEC S.p.A. declines all responsibility for any damage due to improper use of the machine, partial or hasty reading of the information contained in this manual.
HOW TO USE THIS MANUAL This manual is intended to provide a complete support for installation of VMF systems. These systems are made up of several elements which, once installed correctly, must communicate one with another forming a network of devices which will work automatically.
VMF system - Guidelines for system As specifi ed in the introduction, this manual will guide the installer for the correct implementation of a VMF system based on a practical comprehensive example. Management of 5 distinct zones thus divided: A NIGHT zone (composed of two rooms) where a ducted INVERTER unit is installed, making it possible to control the unit by a wall-mounted panel as well as by a centralised panel.
ATTENTION: some elements of the system are NOT available as AERMEC accessories; the installer is in charge of choosing, dimensioning and adapting material to the VMF system; however, in this example, these components will be listed generically WITHOUT REFERRING TO ANY SPECIFIC SIZE.
Page 8
DHW storage tank All of these parts are NOT supplied by Aermec, but are considered as necessary parts to implement the VMF system; the general connections to insert them in the VMF system will be indicated for them.
Hydraulic diagram of VMF system NOTE: VMF systems fully manage an air conditioning/heating system and relative domestic hot water production; however before implementing a control system, the loads which will be connected to it must be highlighted. ATTENTION: the installation of the components to implement the system are not taken into consideration in this manual;...
VMF System - Implement the technical room All the components required to manage the hydronic system for heating/air-conditioning and production of domestic hot water will be installed inside the technical room; in this specifi c case, the elements installed in the technical room are: (1) Heat pump ANLI070HX (this component is installed outside);...
Page 11
Sequence of operations to be performed to install the various components: (1) Install the selected heat pump; the unit must be appropriately installed electrically and hydraulically according to that described in the system design. The heat pump is connected to the MODBUS serial line by means of the MODU-485A accessory (see the relevant documentation to install this accessory).
The fi gure to the left indicates which rooms make up zone A; the master unit installed in this zone is identifi ed on VMF-E5 by the label “NIGHT A”. In this case, the zone is served by one unit alone, and it is therefore managed as master.
Page 13
Sequence of operations to be performed to install the various components: (1) Install the FCXI-P fan coil: this unit is the only fan coil of the zone (MASTER). The unit must be appropriately installed electrically and hydraulically following the instructions provided in the fan coil documentation; the duct must be properly sized based on the features of the fan coil.
The fi gure to the left indicates which rooms make up zone B; the master unit installed in this zone is identifi ed on VMF-E5 by the label “NIGHT B”. In this case, the zone is served by one unit alone, and it is therefore managed as master.

Sequence of operations to be performed to install the various components: (1) Install the Omnia HL fan coil: this unit is the only fan coil of the zone (MASTER). The unit must be appropriately installed electrically and hydraulically following the instructions provided in the fan coil documentation. (2) Install the VMF-E1 thermostat: to be able to manage the fan coil via a VMF network, a VMF-E1 thermostat must be installed on the fan coil, to which the user interface will be linked (in the specifi...
The fi gure to the left indicates which rooms make up zone C; the master unit installed in this zone is identifi ed on VMF-E5 by the label “Bathroom”. In this case, the zone is served by one unit alone (master); the type of unit chosen obliges the installer to use the VMF-E1 thermostat.

(8) Install the advanced VMF-E5 panel: to manage the entire VMF system, the VMF-E5 system control panel must be fi tted (refer to the specifi c documentation to install the panel).
Complete VMF system The fi gure below describes the air-conditioning system used as a reference in this manual. This section describes in detail the hydraulic connections between the fan coils and the collector in the technical room. ATTENTION: the fi gure only indicates the hydraulic connections of all the indoor units. Unit (3) (Zone master Unit (2)
This type of connection is made between the thermostat of a Master unit and the relative control device. The thermostats used as Master can be: • VMF-E0 (only if a supervision system with VMF-E5 is not foreseen); • VMF-E1; • VMF-E18 (only for inverter units);...
