1.3 Unit description
BREVA IN is an indoor unit for ceiling installation, suitable for
use in residential and light commercial premises in combination with
the outdoor unit. The multiple-speed fan DC motor improves
performance and sound comfort.
Control, regulation and programming of the unit are carried out by
means of the infra-red remote control, whose functions and use are
detailed in the user manual.
1.4 Safety and adjustment devices
The device safety and setting are achieved thanks to
–heat exchanger temperature sensor transmitting the detected
value to the control panel, which is trigged in case of abnormal
temperature with regard to the operating mode
–room air temperature sensor transmitting the detected value to
the control panel in order to control the operation of the outdoor
unit and regulate the room temperature
Safety device replacement must be carried out by
Technical Support Service, using only original components.
Please refer to the spare parts catalogue.
IT IS FORBIDDEN to operate the device with faulty safety
systems.
