SETTINGS
Delay on Pow er-up
5 ÷ 15 seconds
Th rou g h t h is p aram et er i s p ossib le t o set t h e d el ay of
transmission of telegrams after a power on by selecting
the time by which the device is allowed to send
telegrams.
In large syst em s aft er a pow er failure or shutdow n this
delay avoids to generate excessive traffic on the bus,
causing slow perform ance or a transmission block.
If there are different devices req uiring send ing telegram s
on the bus after a reset, these delays m ust be
programmed to prevent traffic congestion during the
initialization phase.

Using the Input Counter function it is possible to
count the pulses of a contact connected to the

It is possible t o associate t he send ing of a value w ith
1 bit or 1 byte each tim e the counter reaches the
final value (overflow). the counter can be reset by an
writing on a dedicated 1-bit object.
Using t he "Condition of increase count er"
parameter, you choose whether to count only the
rising, falling or both edges.

to enable a feature associated with a long press that

performed and at the t im e of release the selected

Manage valve independently
In Fan coil on / off m ode it is possible to have the
opening or closing of the valve independent from

parameter "manage valve independently". This
makesvalve adjustment differentials visib l e and can
be set different from those set for speeds. The valve
can therefore be kept open even when the fans are

Force f an coil sp eed
In fan coil operation (in 1-bit or 1-byte mode), you
can force the use of just one speed and bypass the
aut om atic speed selection. This mode is useful, for
exam ple, in sm all room s such as hotel room s, for
exam ple or in any case w here the fan speed m ay
bring noise. To activate forcing, you m ust act on the
1-bit object that sel ect s AUTO / MAN and then on
the object that activates the desired speed (3x1 1-
bit object or 1 object at 1-byte in% mode)

When using fan coil, you can also activate "fan" or

2nd Stage Object
Th e 2n d St ag e ob ject is an ad d it ion al co n t ro l ob ject
for the regulation of a second heating or cooling
equipm ent; a 1-bit or 1-byte control can be set for
this object; if the control is a byte it is possible to set
PI con t rol (Prop ort ion al Int egral). Wit h t h e
"Ban d w id t h " p aram et er you set h ow m uch t h e
current setpoint is sh ift ed to manage the switching
on and off of the equipm ent controlled by the 2nd
st ag e ob ject . Fo r exam ple, if the setpoint is 20 ° C
and "Band w idt h" is set = 1 then the set point for the
part controlled by the 2nd stage object will be 20-1
= 1 9 ° C; v i c e v er sa i f "B a n d w i d t h " i s = -1 then the
2nd stage setpoint will be 20 - (- 1) = 20 + 1 = 21 ° C.
If the equipment controlled by 2nd Stage is
a 1,2 or 3-sp eed fan coil it is su gg est ed t o set t h e
2nd stage as 1 Byte and to send the control value %
in the logic called "proportional sp eed /fan co il

Tem perature probe failure / out of range
measurement
If the tem perature probe is disconnect ed or
in short circuit the control action is
interrupted and the controlled actuators are
sw it ch ed off.
Th e val u e o f t em p erat u r e sen t o n t h e b u s in
case of probe disconnection or short circuit or
for out of range m easured value is 0 °C
(accor d in g t o KNX DPT_Val ue_Tem p 9.001)
Tem p er at ure alar m ob ject
Alarm objects are available for each therm ostat and
for each tem perature probe; in case of probe failure
or out of range m easurem ent, a t elegram w it h value
"1" is sen t t o t h e b u s on a 1-bit communication
object; as soo n as t h e t em p erat u re sen sor is
operating again, the value "0" is transm itted.
To correct l y m an ag e t h e in t ern al o r rear sen so r or
KNX sen so r via bus, refer to the follow ing
configuration m odes:
CONFIGURA TION MODE 1
Only prob e connected to input
if the tem perature probe is disconnected or short-
circuited, the m onitoring action is interrupted and the
controlled actuators are deactivated.
probe / short circuit disconnection / out of range
measurement:
Obj "Tem p erat u re" is not sen d
Obj "Alarm " sen d "1"
CONFIGURA TION MODE 3
Only KNX tem perature via bus
Th e KN X p ro b e i s read c on si d er in g t h e last val u e
received on the Obj "KNX probe tem perature".
If the KNX probe value is out of range or t he
monitoring timeexpires:
Obj "Alarm " send "1" until KNX tem perature is
received again.
CONFIGURA TION MODE 3
Mix of probe connected to input and KNX
temperature via bus
Th e KN X p ro b e is read b y con sid erin g t h e l ast value
received on the OBJ "KNX tem perature probe".
Th e valu e of t h e t em p erat u re sen t on t h e b u s is t h e
weighted average between the values of the front
probe and KNX.
If the value of the KNX p robe is out of range or the
monitoring time expires without having received any
message, the thermostat starts by considering only
the other probe until it receives a new valid value
from the KNX probe; in this case the bus value is again
considered.

10. Th er m ost at behaviour on bus
failure, recovery and download
Behaviour on bus voltage failure
On failure of bus voltage no actions are executed by
the device; behaviour of controlled actuators m ust
be set using their own parameters.
Behaviour on bus voltage recovery
On bus voltage recovery all the com m unication
objects are set to 0 except for objects for w hich a
parameter is d ef in ed f or t h e in it ial val u e; t hermostat
keeps these values in m em ory and restore them
after recovery:
Heat / Cool m ode
HVAC Mode
Base Setpoint
Set p oin t A d just m en t
Force val u e in m an u al m o d e
Vent ilation
Con t ro l val u es (i.e. co m m an d s t o act uat or s) are
calculated using act ual setpoint and tem perature.
After power on device recalculates the
com m ands to actuators and switch them
on, if necessary, otherwise does not carry out any
action; you are recomm ended to set the behaviour
of actuator in order to switch the heating / cooling
equipm ent off aft er bus pow er on.

For ot h er com m unications objects t he behaviour is
identical to bus voltage recovery.
