Terminals
Terminals can be of the following types:
oor circuit•
fan coils•
radiators•
low temperature radiators•
Dierent terminals have dierent water temperature
requirements.
To ensure comfort, it is suggested not to use, at the
same time, terminals with dierent water temperature
requirements.
Example: it is possible to use oor circuit for heating and fan
coil for cooling, but using both at the same time (in heating
or cooling) will cause discomfort.
Floor circuit is the recommended terminal, as it ensures the
best energy eciency.

Room temperature control
Dierent terminals (T1, T2…Tn) can be placed in a single
room or in multiple rooms.
Each of them can have a thermostat, to stop the terminal
when a certain temperature is reached.
It is possible to control 1 room with a user interface or a
thermostat connected to the unit.
This room should be the one with the highest heating/
cooling requirements.
In this room it is not required to place a thermostat on the
terminal/s.
It is suggested to place a thermostat on terminals placed in
rooms with signicantly dierent thermal requirements.
It is recommended to control the room with the user
interface; this way the control adjusts water temperature
to meet the setpoint and comfort and energy eciency are
optimized.
If no user interface is used:
if thermostats are used, set climatic curves slightly higher •
in heat mode and slightly lower in cool mode
if no thermostats are used (temperature requirements •
should be similar for all rooms), climatic curves must be
set exactly right for both heating and cooling operation
