The RHE unit has a quick access to the main functions.
Accesses :
There are 3 access levels to the controller :
User level (no password) – Access to the start/stop – auto or PV/GV functions and increase of the
set point temperature (+/- 3°C).
Operator level (password) – Access in read and write to adjustments and parameters, but no
access to the system configuration.
Master level (password) - Access in read and write to adjustments and parameters, as well as
access to the system configuration.
The RHE units can operate according to 3 principles of operation :
CAV : Operation at constant airflow
VAV : Operation at variable speed
COP : Operation at constant pressure
User level :
To adjust the temperature set point and the operation mode selection of the unit (use of the time program,
