1. GENERAL FEATURES

thTx is the CAREL room thermostat for residential or commercial environments, offering an easy-to-use interface.

The temperature is set simply and intuitively using the arrows on the touch keypad. The compact dimensions and elegant design make it suitable for any type of environment, as well as being ideal both as a user interface (HMI) for heat pumps, rooftop units, AHUs, fan coils, etc., and as a zone control display for centralised systems. The RS485 serial connection via Modbus® protocol can manage multiple thTx devices connected to the same programmable controller, for synergistic control. The thermostat can work in stand-alone mode as a room thermostat, or can be connected to programmable controllers for zone management in radiant systems. Depending on the model, it can be equipped with a temperature probe or a temperature and humidity probe, and is available with 230 Vac or 24 Vac/Vdc power supply. thTx can also manage a three-speed fan.

The parameters and outputs can be set on the terminal in two possible ways: either directly on the display (using the buttons and parameters shown in Table 3.b) or via Modbus, setting the parameters shown in Table 3.c.

2.2 RS485 address setting

Select parameter E5 (communication address) to set and confirm the thermostat's RS485 serial address.

Up to 32 thermostats can be connected. The serial address must be in the range 1 to 207 (default address = 1).

This parameter can be set via Modbus variable HR 249.

Notice: the settings via Modbus do not require a reboot and take it immediately.

Communication modes

Protocol type: RTU

Data bits: 8

Stop bits: 2

Parity: None

Settable via menu E25 (stop bits) E26 (parity) or via Modbus variables HR340 and HR 341 respectively.

Notice: the settings via Modbus do not require a reboot and take it immediately.

BMS data transmission speed

Access menu parameter E24 (baud rate) and confirm the value:

• 0=19200 (default)

· 1=9600

• 2=4800

This parameter can be set via Modbus variable HR 250.

Notice: the settings via Modbus do not require a reboot and take it immediately.

2.3 Using the terminal

Setting the parameters

To access the menu for setting the parameters, switch the thermostat off using the ON/OFF button, press and hold

"MODE

for 5 seconds, then enter the password (0022).

Subsequently, the password can be changed using menu parameter E23. The complete list of parameters is shown in Table 3.b

Setting the mode

To set the operating mode, press the Mode button, the icon at the bottom left will change to Heating (sun) / Cooling (snowflake) / Ventilation (fan). The mode can also be viewed via Modbus parameter HR140

SET/FAN button

The button is used to change the fan speed and therefore the output (EL/EM/EH) of the three-speed fan. It is also used to confirm the settings (set point and in the settings menu).

Pressing

Pressing also selects the desired speed (low, med, high) or automatic (Auto), with the same setting sent via Modbus (register 141)

Switching the thermostat off and on (ON/OFF)

The thermostat can be switched off and on both directly on the thermostat, or via Modbus.

To switch it on, press ; press again to switch the thermostat off and deactivate the relay.

The thermostat is switched off and on via Modbus register HR143 (0 = OFF, 1 = ON).

Enabling the buzzer

To manage the buzzer, access menu parameter E4 (enable buzzer) and confirm:

- 0 = Disabled;

- 1 = Enabled;

Lock keypad

When the thermostat is in normal operation, press Up & Down for 3 seconds to lock the display, with the padlock icon shown. The same can be done via Modbus, setting variable HR165.

Relay control

Relay control by the user is available in both cooling and heating modes.

- Cooling set point (

- Heating set point (

Parameter dF (differential) in the parameters menu defines the differential in both heating and cooling mode. The set point must be set by the user. In addition to managing cooling and heating, the relay can also be used for humidity control, via menu parameter E28.

Set point

Switch on the thermostat, use the up arrow to increase the set point, or use the down arrow key to decrease it, 0.5 degrees at a time. The temperature can also be set via Modbus variable HR144.

Notice: the maximum and minimum set point value can be limited. A bles HR145 and HR146 and menu parameters E6 and E7.

The same thing applies when the relay is configured for managing Humidity mode, in which case the set point has increments/decrements of 1% RH; the set point value can also be set via Modbus variable HR 134.

Notice: the maximum and minimum set point value can also be used via Modbus variables HR152 and HR153 and menu parameters and E23.

Diff erential

To set the Temperature differential, access menu parameter E19, while for Humidity access menu parameter E21. The increment for the temperature differential (HR58) is 0.1, from 0.0 to 5.0. The increment for the Humidity differential (HR50) is 1, from 0 to 20.

Humidity control

In models fitted with a humidity probe, the data is displayed next to the temperature value. The relative humidity value can also be read via Modbus register HR134.

Frost protection mode

This can be enabled by using menu parameter E10. Frost protection is only available during heating mode; when the temperature drops to 5.0°C, frost protection is activated, while when the temperature is above 8.0°C, frost protection is interrupted by the relay.

Alarm

When one of the following alarms is present, the error code is displayed on the LCD. Modbus coil 32 takes the value 1.

- if the error is on the temperature sensor, the LCD displays "E1", - if the error is on the humidity sensor, the LCD displays "E3".

Temperature sensor calibration

To adjust the temperature calibration, access menu parameter E8 (temperature

calibration); the range is between -9 and +9 °C, with

± 0.1 °C steps. The same configuration can be done via Modbus, setting variable HR10

Humidity sensor calibration

Available only on models with humidity sensor. To adjust the humidity calibration, access menu parameter E9 (humidity calibration); the range is -20 to +20 RH% with ± 0.1% RH steps. The same can be done via Modbus, setting variable HR57.

Manual mode

In addition to stand-alone mode whereby the thTx automatically manages the outputs based on the set point values and the confi guration, the display can also be operated via Modbus, overwriting the values and therefore completely managing the icons and related outputs.

To enable this mode, simply set the desired parameters via Modbus:

• Coil 51 is used to manually set the relay status (relay management configuration) [0=Automatic, thTx; 1=manual, via Modbus]
• Coil 59 is used set the MODE [0=Automatic, thTx; 1=manual, via Modbus]
• Coil 60 is used to configure the Fan [0=Automatic, thTx; 1=manual, via Modbus]

Management of the icons on the display

In the default configuration, the thTx can operate in Heating / Cooling / Ventilation mode; setting menu parameter E12 or Modbus register HR350, certain icons can be displayed, specifically:

0: The fan operates and is visible in both heating and cooling modes

Mode Icon shown Ventilation ramp		Med
	YES YES
	YES YES
	YES YES

1: The fan operates in cooling mode but is not visible in heating mode

Fig. 2.c

Now set HR140 (S_MODE) to completely overwrite the MODE; setting the register to specific values will display the corresponding icon:

0x03: Cool (●);

0x04: Heat ( )

0x05: Ventilation (☐);

0x255: NO ACTIONS (all icons cleared); this setting allows the thTx to be used as a room probe only.

Cool On Heat On 28.0 °F C 30 % SET Low Heat

Fig. 2.d

Setting variable COIL 60, "Fan - button selection" managed via Modbus RS485, icon 4 will be shown in the top left of the screen:

Now set HR141 (S_FAN) to completely overwrite the fan speed; setting the register to specific values will display the corresponding icon:

0: all OFF (♣);

1: Fan_Speed1 (Low);

2: Fan_Speed1 + Speed2 ();

3: Fan_Speed1 + Speed2 + Speed3 (High);

255: Fan_Speed1 + Speed2 + Speed3 + Auto (♣ AUTO).

Notice: when the fan logic is managed independently by the thTx and the fan is set to AUTO, the device has two differentiated functions, depending on whether it is in cooling or heating mode.

Cooling mode Heating mode

1. When the room temperature is ≥ the set temperature +1°C, the fan operates at low speed;
2. When the room temperature is ≥ the set temperature +2°C, the fan operates at medium speed;
3. When the room temperature is ≥ the set temperature +3°C, the fan operates at high speed;

4. When the room temperature ≤ the set temperature, the relay opens and the fan stops.

5. When the room temperature is ≤ the set temperature -1°C, the fan operates at low speed;

6. When the room temperature ≤ the set temperature -2°C, the fan operates at medium speed;
7. When the room temperature is ≤ the set temperature -3^ , the fan operates at high speed;
8. When the room temperature is ≥ the set temperature, the relay opens and the fan stops.

Tab. 2.b

Notice: in ventilation mode, the fan speed has no relation to the set temperature.

Relay management

By setting variable COIL 51, "Relay management configuration" via Modbus RS485, icon 2 will be shown in the top left of the screen:
