Q20 Multi-Zone Controller for Underfloor Heating and Radiators via Manifold – 8 Zones, RF (Wireless)

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.

Technical Data for the Quicksmart Q20 Controller:

• Power Supply: 230 VAC 50/60 Hz
• Circulation Pump Output: 230V
• Frequency: 868 MHz for thermostat connection
• 8 zones (5 actuators per zone)
• Boiler Output: voltage-free output
• Current: 5A for each output
• Compatible with NC (Normally Closed) or NO (Normally Open) actuators
• Dimensions: 35x118x59.5 mm

Pairing with the Q20 Thermostat

After the central unit is powered on and connected to the system, follow these steps:

–  On the unit, press the left and right arrows to select the desired channel (from 1 to 8). The selected zone will flash slowly. Then press the SET button — the LED will start flashing rapidly.

–  Continue on the thermostat. Turn it off, then press and hold the M button until the pairing code appears on the screen. Then press the up button.

–  Wait until the LED on the control unit turns off. Pairing is now successfully completed!

If you want to pair the same thermostat with multiple zones, move to the next zone and press SET again.

–  Turn the thermostat back on.

Pairing with the Q30 Thermostat

After the central unit is powered on and connected to the system, follow these steps:

–  On the controller, press the left and right arrows to select the desired channel (from 1 to 8). The selected zone will flash slowly. Then press the SET button — the LED will start flashing rapidly.

–  Continue on the thermostat. Keep the thermostat turned on and press and hold the O and Up buttons for 5 seconds to enter pairing mode. Then press the Confirm/Connect button to begin the connection process.

–  Wait until the LED on the controller turns off. Pairing successfully completed!

If you want to pair the same thermostat with multiple zones, move to the next zone and press SET.

The Q30 thermostat must be reset if re-pairing is required (Advanced Settings, menu 15).

Then, you can check if the thermostat and the Quicksmart Q20 Central Unit are working properly by setting the thermostat temperature higher than the current room temperature.

The system should start heating; when heating is active, the corresponding circuit LED on the unit will light up — this means the actuator is working and has received the command.

To disconnect the thermostat from a set channel on the Qsmart Unit, press the left or right arrows until the LED for the desired zone lights up. Press the RESET button for 2 seconds to disconnect.

If the Qsmart Central Unit needs a factory reset, press and hold both the left and right arrow buttons for 10 seconds, until all LEDs light up.
If the unit becomes unresponsive, turn off the power supply for a few minutes.

Pairing with the Q20 Receiver

1. Press and hold the Pairing button on the receiver until LED 2 starts flashing rapidly.

2. On the Q20 Central Unit, press the left or right arrow buttons until you reach the corresponding boiler LED, which will flash slowly.
   Press the SET button; the green LED will now flash rapidly.

3. When the LED on the Receiver stops flashing, pairing is successful!
   On the controller, press SET again briefly within 5 seconds to exit pairing mode.

Repeat the procedure if you want to pair multiple Q20 units with the same receiver.
