NETWORK SETTINGS

The VMF-E0R/VMF-E18R thermostats are designed
to communicate with the remote control panel of the
same VMF-E4 family (mandatory accessory).
The serial communications protocol is Modbus and
a TTL network, which is used for the exchange of
information within a small network of fan coil units
between one and six units, of which one is Master and
a maximum of five are Slaves.
The Master fan coil unit is the one connected to the
VMF-E4 control panel, and sets the following points:
• Control setpoint.
• Operating mode.
Off: Units off.
AUTO: The thermostat maintains the tem-
perature setpoint by changing the fan speed
in Automatic Mode, as a function of the space
temperature relative to the setpoint.
V1: The thermostat maintains the temperature
setpoint by On-Off cycles only using the Mini-
mum Speed of the fan.
V2: The thermostat maintains the temperature
setpoint by On-Off cycles only using the Medium
Speed of the fan.
V3: The thermostat maintains the temperature
setpoint by On-Off cycles only using the Maxi-
mum Speed of the fan.
AUX: The thermostat forces into heating mode
and maintains the temperature setpoint through
7. INSTALLATION OF THE ELECTROSTATICALLY PRECHARGED FILTER
• Installation
−
Remove the fi lter frame from the unit intake.
−
With the point of a suitable tool press on the
internal hooks of the grille.
−
Remove the fi lter from the sealed packaging.
−
Insert the fi lter within the air intake grille.
−
Reassemble the fi lter frame.
−
Refi t the fi lter frame to the unit intake.
• Characteris cs
Class 2 (UL 900) fire resistance.
Easily extracted. The filter is supplied in sealed
packaging to be opened only at the time of use.
The electrostatically precharged filter lasts
two years from the time of opening the sealed
packaging, after which time it act like a normal
filter. For this reason it is recommended to
replace the filter after two years. Replacement
filters are available from Aermec service centres.
• Maintenance
Clean frequently. Remove any accumulated
dust with a vacuum cleaner. The use of water or
detergents greatly accelerates the discharge of
the electrostatic effect.
