T1, T2, T3: zone 1 terminals
C1, C2, C3, C4, C5, C6: thermostats connected to terminals
CA: user interface (additional or shifted from hydronic
module) or sensor or thermostat connected to 2 zone kit;
placed in zone 1
CB: user interface (additional or shifted from hydronic
module) or sensor or thermostat connected to 2 zone kit;
placed in zone 2
Terminals
Terminals can be of the following types:
floor circuit
fan coils
radiators
low temperature radiators
Different terminals have different water temperature
requirements.
2 zone kit allows to use, at the same time, terminals with
different water temperature requirements.

Room temperature control
Different 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 up to 2 rooms (placed in different
zones), with a user interface or a thermostat connected to
the unit.
In each zone, the controlled 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 significantly different thermal requirements.
In one zone, a room sensor (33AW-RRS01) can be used
instead of a user interface.
If a sensor is used, in that zone humidity information and
temporary setpoint override are not available
It is recommended to control the room with the user
interface, or at least with a room sensor; this way the control
adjusts water temperature to meet the setpoint and comfort
and energy efficiency are optimized.
If no user interface/room sensor 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.
