9.16 - 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.

9.17 - Touch Pilot control
The interface of the "Touch Pilot Control" has the following
characteristics:
•
It has a 5-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.
