Q20 Controller for underfloor heating and radiators through distributor, 8 zones

Q20 Underfloor Heating Controller

The central command unit of the Q20 underfloor heating automation system can send and receive control signals for 32-60 actuators from up to 8 wireless thermostats and can control both the boiler and circulation pump. The system works with any distributor and actuator.

Controller functions of the Quicksmart Q20 Underfloor Heating Automation:

• Wireless connection and control with the central unit.
• Wireless connection of two Q20 controllers with one receiver (for multi-story houses).
• Wired connection to the central unit (if not opting for wireless).
• Wireless connection with ambient thermostats.
• Compatible with any underfloor heating or radiator heating distributor.
• Selectable heating or cooling mode for heat pumps.
• Allows connection of the same thermostat to multiple zones, up to 8 thermostats and zones.
• Selectable NO or NC actuators, supporting up to 32/60 thermal actuators.
• Adjustable boiler and pump delay time from 0-6 minutes.

Pairing Controller Q20- Thermostat Q20:

Once the Central Unit is powered and connected to the system, follow these steps:

1. On the Central Unit, press the left-right arrows and select the channel you want to use from 1 to 8. The selected zone will blink slowly. Then, press the SET button, and the LED will blink rapidly.
2. Continue with the thermostat. Turn it off, then press and hold the "M" button until the pairing code appears on the screen, and then press the up button .
3. Wait for the LED on the Central Unit to turn off. Pairing is successfully completed!
4. If you want to connect the same thermostat to multiple zones, go to the next zone and press SET.
5. Turn the thermostat back on.

You can check if the thermostat and the Q20 Central Unit are working correctly by setting the thermostat to a higher temperature than the room temperature. The system should start heating; the corresponding circuit LED on the Central Unit will light up, indicating that the actuator is working and has received the command.

To disconnect the thermostat and its set channel on the Q20 Central Unit, press the left or right arrows until you reach the desired zone LED, then press and hold the RESET button for 2 seconds to disconnect.

If the Q20 Central Unit requires a factory reset, press and hold both the left and right buttons for 10 seconds until all LEDs light up. If it locks up, cut off the power for a few minutes and then reconnect.
