Room Thermostat Placement

Place the Room Thermostat in the most frequently used room (e.g., living room). Avoid locations with:

• Poor air circulation (e.g., room entrance, near windows).
• Proximity to heating/cooling units (radiators, stoves).
• Direct sunlight.

Battery Placement

1. Remove the battery cover on the back of the Room Thermostat.
2. Insert 2 new AAA alkaline batteries, ensuring correct polarity.
3. Close the battery cover.
Replace both batteries simultaneously. A low battery warning [battery-low-warning] will appear on the screen when batteries need replacement. Remove batteries if the product will not be used for over 15 days to prevent malfunctions.

Receiver Placement

When placing the Receiver, ensure:

• No physical contact with the heating/cooling unit.
• Protection from liquids and dust.
• Avoidance of mounting on metal surfaces.
• Installation away from electrical cables and electronic equipment (computers, TVs).
• Installation away from large metal structures or building materials with fine metal meshes (special glass, concrete).
• Distance from the Room Thermostat does not exceed 20 meters or 2 floors.
• Receiver is at least 50 cm away from the heating/cooling unit.

Receiver Setup and Wiring

Setup Steps:

1. Shut down the heating/cooling unit and its power source (fuse, socket).
2. Connect one end of the heating/cooling unit connection cable to the COM terminal and the other to the NO input of the Receiver, as shown in the wiring diagram.
3. Connect the other ends of the cable to the room thermostat connection terminals as specified in your heating/cooling unit's user manual.
4. Connect the Receiver power cable to the Receiver and then to the fuse connected to the heating/cooling unit.
5. Turn on the fuse first, then the heating/cooling unit.
6. Press the Receiver's manual usage button for 2 seconds; the orange light should blink. Ensure the heating/cooling unit is operating. Press the button again for 2 seconds to turn off the orange LED.
7. Proceed to pair the Room Thermostat with the Receiver.

Wiring Diagram Description: The diagram shows connections for the Receiver (COM, NO, AC 230V) and how they connect to the HEATING/COOLING UNIT.

Warning: Electrical installation and work within the heating/cooling unit must be performed by qualified professionals.

Pairing the Room Thermostat and Receiver

1. Press the Receiver's sync button for 2 seconds until the green light blinks.
2. With the Room Thermostat turned off, press and hold the "ON/OFF" button for 3 seconds.
3. Press the "ON/OFF" button until the pairing menu [menu-symbol] appears.
4. While the Receiver's LED is flashing green, press the "Up" or "Down" buttons on your Room Thermostat.
5. If pairing is successful, the green flashing LED on the Receiver will become steady. The devices are now paired.

Room Thermostat Temperature Calibration

Temperature sensors are sensitive. Calibrate the thermostat if you need to match readings with other thermometers.

1. With the device turned off, press and hold the "ON/OFF" button for 3 seconds.
2. Press the "ON/OFF" button until the calibration menu [menu-symbol] appears.
3. Use the "Temperature Adjustment Buttons" ([up-arrow], [down-arrow]) to set the desired temperature difference, adjustable between -8°C and +8°C.
4. Press the "ON/OFF" button until the device turns off to save settings and exit.

Room Thermostat Heating/Cooling Modes

To switch between heating and cooling modes:

1. With the device turned off, press and hold the "ON/OFF" button for 3 seconds.
2. Press the "ON/OFF" button until the mode selection menu [menu-symbol] appears.
3. Use the "Up" or "Down" buttons to select between [heating-symbol] (heating) and [cooling-symbol] (cooling).
4. Press the "ON/OFF" button until the device turns off to save settings and exit. The device will operate with the new settings upon startup.

Room Thermostat Hysteresis Settings

Hysteresis determines how much the temperature must deviate from the setpoint before the system activates or deactivates. This prevents rapid cycling.

Hysteresis Positive Menu:

The factory setting is 0.5°C, adjustable between 0.1°C and 2.0°C. If the room temperature exceeds the set temperature by the hysteresis positive value (e.g., 22.5°C when set to 22.0°C), the heating unit will stop, or the cooling unit will start.

To adjust:

1. Turn the device off, then press and hold "ON/OFF" for 3 seconds.
2. Press "ON/OFF" until the hysteresis positive menu [hysteresis-positive-symbol] appears.
3. Use "Up" and "Down" buttons to adjust the sensitivity.
4. Press "ON/OFF" to save and exit (or wait 10 seconds). Changes are saved upon device startup.

Hysteresis Negative Menu:

The factory setting is -0.5°C, adjustable between -0.1°C and -2.0°C. If the room temperature drops below the set temperature by the hysteresis negative value (e.g., 21.5°C when set to 22.0°C), the heating unit will start, or the cooling unit will stop.

To adjust:

1. Turn the device off, then press and hold "ON/OFF" for 3 seconds.
2. Press "ON/OFF" until the hysteresis negative menu [hysteresis-negative-symbol] appears.
3. Use "Up" and "Down" buttons to adjust the sensitivity.
4. Press "ON/OFF" to save and exit (or wait 10 seconds). Changes are saved upon device startup.

Open Window Detection Feature

This feature detects sudden temperature drops (over 5°C within 15 minutes) and turns off the heating/cooling unit to save energy. In heating mode, if detected, the system enters an alarm state and turns off the heating for 10 minutes, displaying a warning [open-window-detected-warning]. The heating unit reactivates after 10 minutes if the window is closed. If the temperature continues to drop, it turns off again. In cooling mode, sudden temperature rises are considered.

To enable/disable:

1. Turn the device off, then press and hold "ON/OFF" for 3 seconds.
2. Press "ON/OFF" until the open window detection menu [open-window-detection-symbol] appears.
3. Use "Up" or "Down" buttons to select "ON" or "OFF" and press "ON/OFF".
4. Press "ON/OFF" to save and exit. The setting is saved upon device startup.

Room Thermostat Working Logic

The thermostat uses the average room temperature over the last 40 seconds as a basis for its operation.

Heating Mode Logic:

The heating unit starts when the room temperature drops below the set temperature minus the hysteresis negative value. It stops when the room temperature exceeds the set temperature plus the hysteresis positive value. This maintains the temperature within a defined range.

Example Graph Description: A graph shows room temperature fluctuating around the set temperature. The heating unit turns ON when the temperature drops below the lower hysteresis threshold and turns OFF when it rises above the upper hysteresis threshold.

Cooling Mode Logic:

The cooling unit starts when the room temperature exceeds the set temperature plus the hysteresis positive value. It stops when the room temperature drops below the set temperature minus the hysteresis negative value. This maintains the temperature within a defined range.

Example Graph Description: A graph shows room temperature fluctuating around the set temperature. The cooling unit turns ON when the temperature rises above the upper hysteresis threshold and turns OFF when it drops below the lower hysteresis threshold.

Synchronous Operation and Signal Loss: The thermostat sends status signals to the Receiver every 10 minutes. If the Receiver does not receive a signal for 22 minutes, it assumes a connection break and stops operation for safety. Upon power restoration, the Receiver waits for an 'operate' signal from the thermostat before activating the heating/cooling unit.

Factory Settings Reset

To reset the thermostat to its default factory settings (calibration, modes, hysteresis):

1. Turn the device off, then press and hold "ON/OFF" for 3 seconds.
2. Press "ON/OFF" until the reset menu [menu-symbol] appears.
3. While in the reset menu, select the "reset" option [factory-reset-symbol] using the "Up" or "Down" buttons and press "ON/OFF".
4. The device will turn off and reset.

Frequently Asked Questions (FAQ)

Is my Room Thermostat compatible with my heating/cooling unit?

The thermostat is compatible if your heating/cooling unit has on-off connections. Consult your unit's operating manual or service for details.

How will I connect my heating/cooling unit with my Receiver?

Professional installation is recommended. Use 2x0.75 mm² cable. Connect one end to the room thermostat connection terminals as per your unit's manual, and the other end to the COM and NO inputs of the Receiver. Cable end direction does not matter.
