ELECTRICAL CONNECTIONS
POWER SUPPLY
The thermostat can operate at 50 Hz/60 Hz, and the voltage tolerances are 230V ± 20%.
CONNECTIONS
Two wire power supply AWG18 cable (Cable section: 05 mm² to 1.5 mm²) connected to 230 VAC (L+N) terminals.
Shielded and twisted pair AWG 20/22 communication cable with drain wire connected to GND. Connect to the
terminals of the board and the thermostat. Maximum length = 500 m.
If the “Cn” message does not disappear from the TH-Tune display, it means that communication between the
thermostat and the control board has failed (possible reasons: wrong connection to the terminals, the “Rx/Tx+” and
the “Rx/Tx-“cables have been swapped; the connection has been made through the wrong connector; etc…).
Proceed to verifying the cable connection and make sure that they are connected to the right terminals.
ATTENTION –To avoid possible electromagnetic interferences, separate the power cable from the
communication cable as much as possible. Never insert them in the same cable conduits including the conduits of
the electrical boxes.
Depending on the unit model, connection can be made to the terminal block instead of directly to the board.
Please refer to the wiring diagrams.
For example: Units equipped with an air flow controller: Connection of the air flow controller to the
thermostat is interspersed with the board. The function of the terminals is to prevent wrong
connections.

OPERATION MANUAL
DISPLAY
- Backlighted LCD display.
- Two alphanumerical 4-character strings.
- Set of symbols to obtain the entire information
of the operation simultaneously on the same
screen.
- Multi-function centre button: rotate to scroll
through the menus or to increase/decrease a
value and press to enter or to select.
ON-OFF CONTROL
Press and hold the button (On / Off) for two seconds to turn the thermostat on or off. The word "OFF" will be displayed on the thermostat
screen when it is in the Off position.
NOTE: The thermostat will show "OFFd" if the remote on-off contact is open and "OFFs" when communication Off is ordered through
Modbus. When switching on for the first time or after a power failure the message “Cn” will be displayed during a few seconds until
communication with the board is established.
TEMPERATURE ADJUSTMENT
Adjust the setpoint temperature by turning the central button.
Th-Tune internal temperature probe calibration
Use a positive or negative correction value that will be added to the probe value. The zero value will not change the probe value.
Press and hold the FAN + ON/OFF keys until a password is required.
Access to the configuration menu with the “22” password and press to validate. Rotate the central button until the
PCAL option appears and select it.
Be careful when changing any other parameter from this menu! That might disable the Th-TUNE.
Turn the central button to modify the correction value and press to validate.
SYSTEM MODES
Press the (Mode) button to scroll through the available operation modes.
Available system modes:
Cooling Mode –The display will show the icon and at the lower right corner the icon.
Heating Mode –The display will show the and icons. This mode is not available for cooling only machines.
Automatic Mode –The display will show: “Auto”. This mode is not available for cooling only machines. This
operating mode will change between cold and heat depending on the selected temperature setpoint. The mode that
is active at each moment will be indicated in the lower right corner of the display: Heating, Cooling.
Only Fan –The display will show two icons at the same time: . The fan will operate in a continuous mode and
will not take into account the temperature value setpoint. Only one speed is available.
NOTE: When the outdoor temperature is very low and you want the machine to operate in the cooling mode, either
by selecting this mode or by selecting the Auto mode. If the machine is NOT equipped with the condensation control
option it could stop due to the activation of an alarm.
Be careful with keeping the Auto mode activated continuously! The conditions that lead to the previous error could
be given.
Indoor Fan Modes
“Fan / Autofan” with Ventilation “Continuous / Auto”
Press the (Fan) button to alternate between the automatic and the continuous ventilation mode.
With automatic fan - The icon on the screen will show "Auto".
The fan only works when there is a request for cold or heat.
Without the automatic fan - The word "Auto" disappears from the icon.
The fan operates in the continuous mode.

- t5: Start up or return to main setpoint
- t6: Night stop or reduce to a more economicalsetpoint. “13:00”
Keep the button “ ” pressed for at least 3 seconds until “Clock” appears (if the
stated hour is not correct you can change it here): turn the central button and
chose “Time band” or select “Esc” for escape.
- In general, so as to scroll through the different screens, turn the central button and
select by pressing it.
Turn the central button to select the desired type of program.
- Daily schedule by selecting every day, weekly schedule (shows all days), or one

central button to select the wished day or days.
By turning the button you can select 6 different screens that correspond to 6
different times throughout the day (refer to the screens).
- On each screen a setpoint temperature is programmed if we want the equipment
to be running or "OFF" if we want to stop it and the time at which it will be
activated. If instead of an hour we select “--:--“, the screen will be deprogrammed
and it will not be activated.
- The time that we can select in each screen will always be greater than the time of
the previous screen.
- The operation mode can not be modified, it will be the one that is active.
- To leave, select the ESC screen.
- The screen figures are illustrative and each user can select the schedule according
to their particular needs.
- After the last time section (t6), the next section will start again from the t1 section
on the following day.
