About this manual
Thank you for choosing A-TOUCH solutions.
The first cha ters of this manual will show you how to configure your unit to
o erate correctly with your climatization system. Later you will learn how to
o erate it on a daily basis. At the end you will have a cha ter about integration with
your A-TOUCH automation system, if this is the case.
The A-TOUCH thermostat is a rogrammable thermostat where you can schedule
different tem eratures for different eriods of each day of the week, both for winter
and summer time. The thermostat can also be included in any scenario and its
keyboards can also be used for light and shutter control, when integrated in an
automation system.

-rogrammable tem erature schedule inde endent for winter and summer
-tem erature scheduling with 3 ON eriods for each day of the week
-rogrammable Minimum and Maximum tem erature
-ossibility to o erate with different ty es of climatization units
-ossibility to use it to drive 2 different climatization machines (1 thermostat
for 2 actuators)
Some more features are available but they will be ex lained in the cha ter
Advanced Settings.
Configuration
The unit allows a number of configurations so that it works as you wish. These
configurations need to be made only once.
The configurations are made in MENU mode. The MENU can be accessed only if the
unit is com letely OFF:

(STBY) for more than 1 second:
othe unit will switch off and the dis lay will show the time.
The MENU is accessed by ressing then the key  (VENT). The menu ste s are:
to select if the schedule should run or not
to adjust the thermostat for Winter or Summer o eration
to adjust the minimum tem erature of the house
to adjust the maximum tem erature of the house
to adjust date and time
to define the winter rogram
to define the summer rogram
to define the unit for heating
to define the unit for cooling
to define the unit ty e

SELECT HEATER AND COLLER UNIT
It is ossible that one single thermostat anel controls 2 different climatization
machines. In that case, one actuator controls for exam le the radiating floor and
another actuator controls for exam le the air conditioning.
The unit defined as LOCAL is the actuator that is connected to the thermostat
anel; the other unit is then the REMOTE actuator.
The REMOTE unit has to be rogrammed to o erate as SLAVE of the LOCAL unit.
Please see the cha ter USING 2 UNITS WITH 1 THERMOSTAT for more details.

If for exam le the LOCAL unit controls a radiating floor, the HEATER UNIT should be
LOCAL if you wish to heat only with it. You can choose to heat with the air
conditioning if you select REMOTE or even BOTH if you want both to heat at the
same time.
The same a lies for the COOLING UNIT. In our exam le, cooling would be made
with the air conditioning. Therefore the COOLING UNIT should be set to REMOTE.
This setting can be changed any time you like.
If for exam le you have no cooling unit, then set it to NONE: the thermostat will
not o erate in Summer mode.
Puting tem orarily both units o erating together can be made without setting the
HEATER or COOLER units to BOTH: just hold the key  (VENT) on the normal
o eration that the second unit will switch on together with the first. Please see the
cha ter USING 2 UNITS WITH 1 THERMOSTAT for more details.
This is how you select the HEATER and COOLER units:
Press key  (ENTER):
- the dis lay shows the actual unit.
Change with key  (UP) or  (DOWN)
Confirm by ressing key  (ENTER):
Proceed the same way for the COOLER unit.
When you confirm with key  (ENTER) the dis lay will show the next
menu item.
UNIT TYPE
The thermostat must be configured for the climatization unit it is connected to
because the o eration is different for several ty es of climatization units. You can
choose the following unit ty es:
RADIATOR usually wall or floor mounted radiators with water, o eration with
on/off of valve
R. FLOOR radiating floor with water, ro ortional o eration
AIRFLOW2 air flow unit with 2 tubes, on/off of valve and 3 ventilation s eeds
AIRFLOW4 air flow unit with 4 tubes, on/off of heat and cool valves and 2
ventilation s eeds with automatic change between Winter and
Summer o eration
AIR CON1 air conditioning, on/off of com ressor and 3 ventilation s eeds
DAIKINFD DAIKIN air conditioning of series FDX equi ed with interface board
KRP413A
AIR CON2 air conditioning, on/off of com ressor and 3 ventilation s eeds but
with delay of 3 minutes to start the com ressor
To select the right unit ty e roceed as follows:
Press key  (ENTER):

UNIT OPERATION
SWITCHING ON AND OFF
The thermostat has 4 modes:
OFF, where the thermostat does not work at all, schedule is OFF
AUTO OFF, where the thermostat runs the rogram you defined but is
in an OFF eriod
AUTO ON, where the thermostat runs the rogram you defined but is
in an ON eriod
MANUAL, where the thermostat was manually switched ON in an OFF
eriod
As you can see, the dis lay contents show the mode of the unit. There is no
difference between AUTO ON and MANUAL because in both modes the unit makes
the same.
In OFF mode the unit shows the time and tem erature. If the time is
missing then the time field does not dis lay.
To switch on, ress key  (STBY):
- the dis lay shows the actual tem erature and the target
tem erature on the to right corner.
When the target tem erature is achieved, the unit will switch the
heating off.
If you wish to switch off the unit, even during the execution of the
rogram, just ress key  (STBY):
- the unit goes OFF.
If you want to switch the unit ON again, just ress key  (STBY):
- the unit goes back to ON mode and the rogram settings are
reloaded.
If the unit has the SCHEDULE function ON then it o erates automatically according
to the schedule defined, switching the climatization on and off according to the
needs. You can always switch it on or off inde endently of the schedule.
Notes:
-In OFF mode, the unit does not control minimum and maximum
tem eratures.
-In AUTO OFF mode the unit controls minimum and maximum tem erature.
These settings are inde ent of the week day.
ADJUSTING THE TEMPERATURE
You can adjust the target tem erature when the unit is in ON mode, no matter if it
is in manual or automatic mode. The new setting will be automatically stored in the
memory.
If the unit is in an ON eriod, the new setting is stored in the rogram of that day
and that moment. If eriods overla and more than one eriod are active in the

moment you change the tem erature, then the new tem erature is stored in all
active eriods, regardless of if they were different or not.
To adjust the tem erature, roceed as follows:
Press the key  (UP) to increase the tem erature:
- the target tem erature is shown tem orarly on the big dis lay and
then goes back to the normal dis lay.
Press the key  (DOWN) if you want to decrease the tem erature:
- the target tem erature is shown tem orarly on the big dis lay and
then goes back to the normal dis lay.
VENTILATION SPEED
The unit ty es AIRFLOW2, AIRFLOW4, AIR-CON1, AIR-CON2 and DAIKINFD have
ventilation and their s eed is controlled by the thermostat.
When you switch on the thermostat, the ventilation s eed is always set to
automatic. In this mode, the ventilation s eed de ends on the difference between
the target tem erature and the room tem erature: the higher the difference, the
higher the ventilation s eed.
You can choose a certain ventilation s eed. However, if you do it then the s eed
will remain as you s ecified, regardless of the difference between target and room
tem erature (manual mode).
To change the ventilation s eed roceed as follows:
Press the key  (VENT) to select the next s eed:
- the new s eed is shown on the to left corner.
Notes:
-The AIRFLOW4 unit ty e only has 2 s eeds, all others have 3 s eeds.
-The transition between one s eed and the next has a ause of about 1
second. This is necessary to avoid relay damage in some kinds of
ventilators.
