2. Product Overview

The WQ610RF room thermostat controls the heating system by sensing air temperature, switching heating on when the temperature falls below the setpoint, and off when it reaches it. Setting a higher temperature does not make the room heat up faster; this depends on the heating system design. Lowering the setpoint saves energy.

The heating system will not operate if a time switch or programmer has turned it off. The best approach is to find the lowest comfortable temperature setting and leave it. For example, set to 18°C and increase by one degree daily until comfortable. Adjusting above this setting wastes energy.

For systems with a boiler and radiators, a single thermostat usually controls the whole house. Individual room temperatures can be managed with Thermostatic Radiator Valves (TRVs). If TRVs are not used, select a temperature suitable for the whole house. With TRVs, set a slightly higher main thermostat temperature and adjust TRVs to prevent overheating.

Thermostats require free airflow to sense temperature accurately and must not be covered by curtains or blocked by furniture. Nearby heat sources like electric fires, televisions, or lamps can affect performance.

The thermostat is compatible with OpenTherm OT+ 4.0. This protocol enables two-way communication between the boiler and thermostat, allowing the boiler's power to be modulated for increased energy efficiency, maintaining room temperature without constant ON/OFF cycling.

PLEASE NOTE! Ensure your gas combi boiler is compatible with the OT+ 4.0 communication protocol. A list of compatible boilers is provided.

Product Advantages:

• Factory-paired and ready for operation.
• Limits maximum boiler temperature via OT+ 4.0 protocol.
• Option to select hysteresis or built-in ITLC algorithm.
• Operates according to time schedules.
• PIN-protected service mode.
• Maximum/minimum temperature limits.
• Temporary temperature override function.

• 2) WQ610RX Receiver
• 2) Short instruction
• 3) Mounting screws

2.3 Proper thermostat location

The ideal position for thermostat mounting is approximately 1.5m above floor level, away from heating or cooling sources. The thermostat must not be exposed to direct sunlight or extreme conditions like drafts. It is not permitted to use the thermostat in atmospheres with explosive gases or flammable liquids (e.g., coal dust) due to fire and explosion risks. If such dangers exist, use additional protective measures like an anti-dust and explosive gases tight cover, or prevent their formation. Furthermore, the thermostat cannot be used in conditions of water vapor condensation or be exposed to water action.

3. WQ610RX receiver

The thermostat communicates wirelessly with the WQ610RX receiver. The receiver is supplied with 230VAC and has a maximum load capacity of 16A. Avoid installing the receiver in places directly exposed to water, moisture, or air condensation. The WQ610RX receiver can operate in two modes: AUTO (automatic) and MANUAL (manual). Select the mode using the switches on the front of the receiver.

3.1 Receiver's switches description

The receiver has two switches:

• TOP SWITCH:
  • ON: Manual mode - receiver is ON.
  • OFF: Manual mode - receiver is OFF.
• BOTTOM SWITCH:
  • AUTO: Receiver operates in AUTO mode (following the thermostat's command).
  • MANUAL: Receiver operates in manual mode (controlled by the top switch).

REMEMBER! For the receiver to work with the thermostat, set the switches to the ON / AUTO position.

3.2 LED indications in the receiver

The status of the WQ610RX receiver is indicated by two LEDs: a red LED (upper) and a green LED (lower).

• Red LED lights up: The receiver is connected to the 230V power supply and paired with the thermostat. The receiver can be enabled by the thermostat if it's in automatic mode (lower switch in AUTO position). It can be started manually if the lower switch is in MANUAL position.
• Red LED flashes: The receiver is in pairing mode, searching for a signal from the thermostat (activate "PAIRING" on the thermostat). Alternatively, the receiver was paired but lost communication due to range or low thermostat battery. The red LED flashes one hour after losing the signal.
• Red LED is off: The receiver is disconnected from the 230V power supply, or the top switch is in the OFF position.
• Green LED lights up: In automatic mode, the receiver received a heating signal from the thermostat. In manual mode (top switch ON, bottom MANUAL switch), the receiver is started.
• Green LED is off: The receiver is not sending a heating signal.

3.3 Wall mounting of the receiver

To wall mount the receiver:

1. Drill two Ø6 mm holes in the wall.
2. Insert plugs.
3. Attach the mounting plate to the wall using the two screws through the marked holes.
4. Connect the necessary cables to the receiver.
5. Hang the receiver on the plate using the designed handles.
6. To attach the back housing: Loosen screws to tilt the back housing. Tilt the receiver cover upwards. Attach the back housing to the wall using the marked holes.
7. Connect the wires correctly (refer to connection diagrams).
8. Place the receiver from above onto the back housing, aligning with the plastic hinges.
9. Tighten the screws from the bottom of the back housing to secure the receiver.

6. WQ610RF thermostat pairing with the receiver

PAIRING refers to the function of synchronizing the transmitter with the receiver again, if it has been removed. WARNING! In the WQ610RF set, the thermostat is factory-paired with the receiver!

To pair the devices correctly, prepare the receiver for synchronization:

1. Ensure the receiver is disconnected from the power supply and its switches are in the AUTO and ON positions.
2. Connect the receiver to the power supply and wait for the red LED to glow continuously.
3. Move the top switch to the OFF position with a quick motion and then back to the ON position.
4. The red LED will start blinking, confirming the receiver has entered pairing mode.
5. Press [Menu] on the thermostat to enter the menu.
6. Use [Up] or [Down] to choose the "PAIR WITH RECEIVER" option, then press [Tick].
7. Confirm "YES" by pressing [Tick].

The pairing process takes up to 10 minutes. When the red LED on the receiver lights up continuously, the devices have been paired on a new frequency. The thermostat will display "PAIRING SUCCESSFUL" and return to normal operation.

7. Test the pairing process

It is important to place the receiver and transmitter where the radio signal is not obstructed. The communication range in an open area is up to 60m. Radio transmission can be affected by thick walls, metal objects, and general radio interference, which can shorten the working distance. The range is generally sufficient for most domestic uses. Test the radio transmission before mounting the regulator on the wall.

To test the link:

1. Press [Menu] to enter the menu.
2. Use [Up] or [Down] to choose the "TEST LINK" option, then press [Tick].
3. The thermostat will send a TEST message to the receiver.
4. The red and green LEDs on the receiver will flash.
5. Your thermostat will indicate that the connection has been tested successfully and will return to normal operation.

8. Factory Reset

To reset the WQ610RF thermostat to its factory default settings:

1. Press and hold the [Up] + [Down] buttons together for 5 seconds.
2. Use [Up] or [Down] to choose YES, then press [Tick].

The thermostat will reset and display the firmware version, then proceed through the initial start-up settings.

9. Error codes

Error codes are displayed only when the thermostat is connected to the boiler via OpenTherm terminals (A/B). Refer to your boiler manual for specific error code interpretations, as each boiler may have different codes.

ERRORS EXAMPLES:

• SERVICE REQUEST ERROR
• LOCKOUT RESET ERROR
• LOW WATER PRESSURE ERROR
• GAS FLAME FAULT ERROR

10. Cleaning and Maintenance

The WQ610RF thermostat requires no special maintenance. Periodically, wipe the outer casing with a dry cloth. DO NOT use solvents, polishes, detergents, or abrasive cleaners, as these can damage the thermostat. There are no user-serviceable parts inside the unit; any servicing or repairs must be carried out by Salus Controls or their appointed agents.
