itself belongs to. It is possible to set a delay in the on/off
switching of the auxiliary output.
The delay may be set in the range of 0 to 7 minutes by
adjusting the trimmer indicated by
permit the output to control a pump, which will wait for the
electro-thermal actuators to open before starting to circulate
water and continue after all actuators have been switched
off, until they are completely closed.
If a pump is controlled by the module, it is useful to enable
the "periodic activation" option (see paragraph on "DIP-
switch options").
Associating thermostats with a chronostat
Through radio signals the thermostats transmit to the relay
module the current room temperature reading and setpoint
programmed on the knob.
Accordingly, the relay module can decide whether to adjust
the setpoint downward for the "economy" function, which
allows the temperature to be regulated so as to save energy
in certain periods of the day.
This function allows the temperature in the room where
the thermostat is installed to be regulated according to two
setpoints: comfort and economy.
The comfort setpoint corresponds to the temperature set
on the knob, whereas the economy setpoint is equal to
the comfort temperature minus a fixed reduction value in
the heating mode (in the cooling mode Tcomfort + fixed
reduction value).
The relay module has 4 trimmers, indicated by
by means of which it is possible to adjust the fixed reduction
value between 0°C and 7°C.
Each trimmer allows you to set the amount of the temperature
reduction for two adjacent channels: for example, trimmer
SB1-2 sets the reduction on channels 1 and 2, trimmer SB3-
4 sets the reduction on channels 3 and 4, and so on.
The economy mode can be activated by the external
"Economy" input via an override command or controlled by
an associated chronostat.
The device permits one or more thermostat-controlled outputs
to be associated with the output of a chronostat, so that
the associated channels will receive from the chronostat an
indication as to the time of day and information about which
setpoint – comfort or economy – should be used to regulate
the room temperature.
The OFF or antifreeze status is likewise received by the
associated thermostats.
If the chronostat is currently set in the comfort mode, the
associated thermostats will abide by the setpoint set on
their respective knobs; if, on the other hand, the chronostat
is currently set in the economy mode the associated
thermostats will apply the temperature reduction as
described above.
Similarly, if the chronostat is off with the antifreeze function
set on 5°C, the associated thermostats will likewise be set
on an antifreeze temperature of 5°C.
The thermostats can have a selector that allows them to be
set in the comfort or economy mode according to the time
schedule of the associated chronostat, or to override the
latter so as to remain always set in the comfort mode or
always off. See thermostat instructions.
See the chronostat instructions to find out how to program
time schedules and comfort and economy temperatures.
In this way a chronostat and the thermostats associated
with it will form a "zone".
For example, in a home it would be possible to create separate
in Figure 2. This will

"zones" for the living area and bedroom area, with room
temperatures in each area regulated according to different
time schedules programmed on two different chronostats.
Procedure for associating thermostats with a chronostat
Before starting the association procedure, make sure that
the address self-learning procedure has been carried out for
all thermostats and chronostats of the system.
1. To start the procedure press the association button "A"
2. The relay module and all the modules connected to the

NOTE
The association procedure can be repeated at any time in
order to make changes or simply carry out a check.
For example, to check which channels a transmitter has or
has not been associated with by means of the self-learning
procedure, follow steps 1 and 2 and exit with 6.
To check the associations with chronostats, carry out the
whole procedure without pressing any buttons corresponding
to thermostats in step 4.
The self-learning procedure cancels the association of a
channel.
Therefore, if the self-learning procedure needs to be repeated
for one or more channels, the association procedure will
likewise have to be repeated as necessary.
It is possible to associate thermostats with chronostats
whose channels reside in different relay modules, provided
they are connected in a chain to the same active antenna.

the channel is controlled by a chronostat or red if the
