To change the value of a parameter:
•
having entered the parameter list of the chiller, fan coil or keyboard, use the up and down arrow keys to scroll through the
pages of the parameters, up to the desired parameter;
•
press on the currently set value;
•
the current value turns red to indicate that it can be changed by using the up and down arrows;
•
select the desired value and press the confirmation tick .
Note
: after selecting the desired value, if you miss the confirmation tick, the previous setting value will be kept.
To copy the value of a parameter to all fan coils:
By pressing the "COPY"
near the set value, this last one will be copied automatically to all present fan coils.

DESCRIPTION OF RFC SYSTEM
First of all refer to the specific RFC manual (MCO01137I0300 FAN COIL REGULATOR).
The RFC system can be installed with the hydronic terminals of the VE, HCN and HCNA series.
There are two ways to install the RFC control system:
1)
Installation inside fan coil compartment
2)
Wall installation using screws
In the standard configuration, the Hi-T2 control panel allows a complete control of the fan coil units; however with a switchable
configuration of the RFC control system, you can get access to some manual features for comfort adjustment. In fact, it is possible
to adjust the setpoint using the main knob giving a slight variation of the setpoint value (up to +/-5°C) that is already set by the Hi-
T2 control panel. Moreover, with appropriate parameterization, you can allow the RFC control system to operate manually on
ventilation; particularly, it is possible to establish whether to keep the automatic regulation made by the Hi-T2 control panel, or to
use the appropriate knob whether to stop or set one of the 3 fan speeds.
