11.17 -Non-return valve (models A and D)
For air-condensed units, a non-return valve is supplied on request in a separate kit. It should be installed
on the liquid line near the condenser, vertically with downward flow. The installation of this valve is abso
lutely necessary when the total charge of the system exceeds the values given in the table:
Model Maximum refrigerant charge without non-return valve [kg]
4S/P/M 4.5
4L/G 2
6S/P 2
6L/G 4.5
8S/P 4.5
8L/G 4.5
5S/P/M 4.5 x 2
5L/G 2 x 2
7S/P 2 x 2
7L/G 4.5 x 2
9S/P 4.5 x 2
9L/G 4.5 x 2
11.18 -Additional temperature and humidity sensor (EEAP)
"EEAP" is an additional temperature and relative humidity sensor similar to the humitemp sensor. EEAP
means "Electronic Environmental Alarm Package".
The sensor can be installed in a representative place up to 20 m from the conditioner and emits an alarm
if the temperature or the relative humidity exceeds one of the four thresholds that can be selected by the
user:
high temperature (from 10C to 50C)
low temperature (from 0C to 30C)
high relative humidity (from 30% to 99%)
low relative humidity (from 10% to 70%).
11.19 -Microprocessor control with graphic display HIROMATIC G
The Hiromatic graphic display terminal is particularly suitable for group management. Indeed, thanks to
the generous dimensions of the display and to its exceptional contrast, it allows the user to move around
freely within the Microface network. Therefore, from a single point, it is possible to control the whole system
without moving from one unit to another. The last 200 events occurring in the system; the graphic
development of the last 24 hours for each of the units connected (stored since the last start-up), the user's
menus available in 8 languages and connectivity through RS 422 to the Hirolink Communication Manager
are just some of the features available with Hiromatic. Moreover, as Hiromatic can be supplied in kit form,
it may be installed either on the unit or on a remote panel for primary supervision of the system.
