INTRODUCTION

Climatization is the main source of comfort of a home but also of costs.
The temperature control in each dependency is not only more comfortable but more
economical because it connects only when necessary. For example, it makes no
sense to heat a bedroom at 18:00 if we are only going to bed at 23:00 hrs.
The ONLY engineers designed a climatization system that ensures maximum
comfort with minimal human intervention and with seamless integration with the
automation system.
The system offers:

• Temperature control of each dependence of the house

• Three operating periods with respective temperature for each day of the week

• Independent programmes for summer and winter

• Multiple control options for central heating, heat pumps, fan coil units, air

conditioning, floor heating, etc.

• Remote control (on/off) by telephone

Since design and comfort is a priority for ONLY, the operation is done via touch
panels of the ONLY TOUCH line in total harmony with the rest of the commands in
the house.

EQUIPMENT

In your house you will probably find two types of climate control units:

• one with an LCD display – OTC-CLIMA

• one or various without LCD – OTC-TERMO

Both are programmable thermostats that can manage independently the
temperature of the room it is in. For this there is a thermal sensor on the bottom part
of the panel that measures constantly the ambient temperature, comparing it with the
programmed temperature for that moment. If necessary, the heating or cooling is
switched on.

CONTROLS AND INDICATIONS

The ONLY climate control units have illuminated touch sensors that function as
buttons. They allow the following functions:

- Turns the unit on and off

- Displays the date

- Allows access to the programming menus

- Indicates the operation and allows control of the fan speed

- Allows navigation to the left in the setup menus

- Allows navigation to the right in the setup menus

- Allows increasing the target temperature or navigation in the menus.

- Allows decreasing the target temperature or navigation in the menus

The LCD indicates the room temperature, the time and the day of the week.
The days of the week are indicated by the numbers 1 to 7
On the OTC-TERMO the LEDs 20º, 22º and 24º indicate the room temperature. In
case the target temperature is changed, these LEDs show the selected temperature
for 2.5 seconds and then return to showing the room temperature.
When two LEDs light up (e.g. 20º and 22º) this means that the temperature is
between them (e.g. 21º). If the room temperature is higher as 24º or lower than 20º
the respective LEDs blink.

CONFIGURATION VIA THE OTC-CLIMA

The OTC-CLIMA allows adjustment of several parameters both local and of other
OTC-TERMO units scattered throughout the house.
Pressing the key enters the setup menu.
With the and keys you can navigate in the menu between the other menu
options. Possible options are:
1-DATA - set the date and time
2-CICLO - cycle selection – summer or winter
3-INVERN - definition of winter programme
4-VERAO - definition of summer programme
5-INSTAL - installation of OTC-TERMO
6-REMOVE - removal of OTC-TERMO
Within the menu the button lets you select the option and the button lets you
exit the current menu and go back to the former.

1. Setting the date and time

Ideal temperatures – OTC-CLIMA

You must have an ideal temperature for summer and winter. This temperature is
selected as the target when climatization is switched on outside the periods defined
in the programme.
This can happen for example when you return home earlier than usual.
In this case you wish to turn on climatization without having to change the
programme. To do this, simply switch it on with the key and the ideal temperature
is automatically selected as target temperature.

Ideal summer temperature

Adjustment of the summer temperature is done by pressing PROG for 2 seconds:

- when touching the panel only the keys and light up.
Press the key to adjust the summer temperature.
On the LCD you will see the selected temperature. You can select between 18º and
29º pressing successively the PROG key.
Once the desired value is selected, you can confirm it with .

- when touching the panel only the keys and light up.
Press the key to adjust the winter temperature.
On the LCD you will see the selected temperature. You can select between 18º and
29º pressing successively the PROG key.
Once the desired value is selected, you can confirm it with .

CONFIGURATION OF THE OTC-TERMO

There are some parameters that can be adjusted directly on the OTC-TERMO.
These are:

- ideal winter temperature

- ideal summer temperature

- operating cycle

Ideal temperatures

The OTC-TERMO is a programmable thermostat with three periods of operation for
each day of the week. During these operation periods the temperature is controlled
in accordance with the programme. Outside the operating periods the climatization is
switched off.

OPERATION

OTC-CLIMA

When the OTC-CLIMA is switched off, touching the panel will only light up the LED
of the key. This means that the only possible operation is switching the unit on or
off.

To switch on the unit press : you will hear two beeps indicating that the unit is on
and the LEDs of some other keys light up.

Manual operation
The OTC-CLIMA can operate in automatic and manual mode. To operate in
automatic mode it is necessary that the unit has the date and time adjusted. If this is
not the case, the unit can only function in manual mode.
If the display shows only the temperature, this means that there is no date and time
adjusted.
In this case, when you switch on the unit with the key, it automatically goes to
manual mode. This is indicated by the LED of the key that blinks or lights up.

blinks - unit switched on but climatization switched off

lights up - unit switched on and climatization switched on
In this last case the LCD indicates  if it is cooling or  if it is heating up.
During manual operation the ideal temperature is the one that is previously adjusted
for the respective season.
If desired, you can edit the target temperature by pressing the keys to increase or

to decrease.

Automatic operation

If the date and time are adjusted, the display shows the time. In this case, when you
switch on the unit it goes to automatic mode.
If the actual time is outside of any defined operating period the unit stays in
STANDY, waiting for an operating period to start.
In this case the key does not light up, indicating that the climatization is switched
off.
Pressing the key switches the unit on in manual mode. The target temperature is
the defined ideal temperature. Climatization is switched on if necessary.
As an alternative, you can press in winter or in summer. In this case
climatization is always switched on being the target temperature the actual
temperature plus (winter) or minus (summer) 1º.
When the time reaches an operating period, the defined target temperature of that
period is selected and the unit switches to automatic mode.
When the program ends, climatization is switched off.

To switch off the unit, press for more than 1 second.

OTC-TERMO

When the OTC-TERMO is switched off, only the LED of the key lights up when the
panel is touched. This means that the only possible operation is switching the unit on
or off.

To switch on the unit press : you will hear two beep tones indicating that the unit is
switched on and the LEDs of some more keys light up.

Manual operation

The OTC-TERMO can operate in automatic and manual mode.
To operate in automatic mode it is necessary that the unit receives the date and
time. If this is not the case, the unit can only function in manual mode.
Since the OTC-TERMO does not have its own clock (there is no display for it) you
can receive the time signal from other units in the system. The ONLY units that send
time signals are the D-BUSDRV and the CENTRALSEC..
As such, when at least one of these units is placed in the system and the date and
time are adjusted, the OTC-TERMO receives the time signal.
If this is not the case, when you switch on the unit with the key, it goes directly to
manual mode. This is indicated by the LED of the key that lights up or starts
blinking.

blinking - unit switched on but climatization switched off

lights up - unit and climatization switched on
During manual functioning the ideal temperature is the one previously adjusted for
the respective season.
If desired you can change the target temperature by pressing the keys to increase
or to decrease the temperature.

Automatic operation

If the unit receives a time signal it goes to automatic operation when it is switched
on.
If the actual time is outside any defined operating period, the unit stays in STANDY
until an operating period starts.
In this case the key stays off, indicating that climatization is switched off.
Pressing the key switches the unit on in manual operation and the target
temperature is the defined ideal temperature. If necessary, climatization is switched
on.
As an alternative you can press in winter or in summer. In this case
climatization is always switched on being the target temperature the actual
temperature plus (winter) or minus (summer) 1º.
When the time reaches an operating period, the defined target temperature of that
period is selected and the unit switches to automatic mode.
When the program ends, climatization is switched off.

To switch off the unit, press for more than 1 second.

INTEGRATION WITH DOMOTICS

The units of the ONLY climatization can be integrated with the rest of the
automation. It may for instance be an advantage in an office to associate the
opening of a blind or switching on a light to switching on climatization. In this way the
user configures the office with the use of just one button. When switching on the light
or opening a blind, climatization is switched on. When switching off the light or
closing a store, climatization is switched off.
For this, the association is done in the same way as any other output of the ONLY
system.
To associate a unit to a button, proceed as follows:

1. press PROG on the OTC-TERMO or OTC-CLIMA

2. then press the automation button that you wish to associate.

To remove the button from the unit:

1. press PROG on the OTC-TERMO or OTC-CLIMA

2. press PROG again for more than 1 second to switch to the mode APAGAR

3. then press the automation button you wish to remove.

Association with Scenarios

The SCENARIO commands are commands that allow the combination of different
states of multiple outputs.
The climatization units can be linked to these scenarios, like the other units.
For the scenario the status of the unit is memorized:

- switched off

- automatic mode

- manual mode
The unit will enter the respective mode when the SCENARIO command is received.

Association with ON or OFF

The commands ON and OFF are commands that define a specific state. Therefore,
the climatization units execute them literally.
As such the command ON switches climatization on independent of the state it was
in. The command OFF switches climatization off, as well as it switches the unit off.

Association of outputs to climatization

It might be necessary to associate automation outputs to the climatization units. This
is for instance the case when you wish to command a boiler with an ON/OFF output
via any ONLY module that is installed near it.
The intention is that this output is switched on if at least one climatization unit is
heating, and switched off otherwise. Therefore, this output must me associated to
the climatization units.
To do this, proceed as follows:

1. press PROG on the output module

2. then press on the climatization unit.
Repeat this for further climatization units.
From now on, the output is turned on when at least one of the associated units is
ON.

FACTORY DEFAULT

VERY IMPORTANT:
The ONLY climatization units have to be configured according to the installation in
which they are used. This configuration should be done by the installer because it
depends on the installation architecture and the physical connections made.
Therefore, you should never reset to the factory default settings, because the unit
will no longer function.
To reset the unit to the factory default, press PROG for more than 10 seconds. At the
end you will hear a long BEEP.
