Variable speed ventilation (30RQP units
only)
30RQP units differ from the 30RQM units by the introduction of
variable speed drives on the fans to optimise the efficiency of the
unit depending on the conditions of use (air temperature, circuit
capacity) and thereby improve the seasonal efficiency (ESEER
and SCOP).
All fans in the same refrigerant circuit are controlled by a single
variable speed drive. Therefore, they operate together at the same
rotational speed. The rotational speed at full load or part load of
each circuit is controlled by an algorithm that continuously optimises
the condensing temperature in cooling mode or the evaporation
temperature in heating mode to obtain the best energy efficiency
of the units (EER and COP) whatever the operating conditions.
Fan motor electrical protection
The motors of a same circuit are electrically protected by the
variable frequency drive in case of short-circuit, locked rotor or
general overload. Each variable drive follows a variable current
curve, based on the frequency from 5 to 50 Hz and the number
of fans controlled.
In case of fan failure (e.g. motor disconnected) the variable drive
will detect this problem and an alert will be sent to the user
interface. Refer to the 30RQM/30RQP control manual for the list
of alarms.

Smart View control
The interface of the "Smart View Control" has the following
characteristics:
-
It has a 4,3-inch colour screen.
-
It is intuitive and user-friendly. Clear and concise information
is presented in the local language (choice of 8 languages).
-
The screen menus can be adapted for different users (end
client, maintenance personnel, Carrier engineer).
-
Unit setting and use are secure. Password protection
prevents unauthorised access to advanced parameters.
-
No password is required to access the most important
operating parameters.
