INSTRUMENTS AND ALARMS
The air-conditioner is fitted with the following instruments:
- High pressure switch/switches
with manual reset (one on
each refrigerant circuit);
- Low pressure switch/switches
with automatic reset (one
on each refrigerant circuit);
- Air flow sensor and dirty
filter sensor (differential pressure
switches);
-
Temperature sensor or room temperature and humid-
ity sensor
(on the units with humidity control);
-
Outlet air limit temperature sensor
Some versions, in addition, have the following sensors:
- Safety thermostat
(in the versions with electric heaters),
with the reset button accessible on the right-hand side of the
electrical panel.
In addition, the following optional devices may be available:
-
Flood sensor made up of:
a) device to be inserted in the special socket on the electrical
panel;
b) Floor sensor (or sensors, connected in parallel) to be posi-
tioned at the points monitored;
-
Fire and smoke sensors
;
-
Hot water temperature sensor,
for reading and enabling
post-heating with hot water;
The pressure test points for the air flow and dirty filter differen-
tial pressure switches are connected in parallel; (on OVER units)
- the positive pressure test point is located on the right-hand
side of the base of the unit;
- the negative pressure test point is located in a position for
measuring the pressure upstream of the fan; (on UNDER units)
- the positive pressure test point is located behind the electrical
panel, upstream of the air filter;
- the negative pressure test point is located in a position for
measuring the pressure upstream of the fan.
