Nuaire Drimaster ECO 2-Way Boost Switch

Health & Safety Considerations

Work only when you have safe access, good lighting and a stable step-stool or ladder if needed. Choose a mounting spot that avoids wet zones and direct heat sources. The switch contains a small lithium coin cell; keep new and used batteries away from children and dispose of them responsibly.

If you plan to pair the switch while another person operates the fan’s diffuser controls, agree hand signals to avoid shouting near stairwells. Do not open or modify the electronics. If at any point you are unsure about the fan’s supply isolation or general electrical safety in the property, ask a qualified electrician to check before you proceed.

Site Preparation

Decide where the switch will be most convenient day to day, typically near a kitchen entrance, utility room or landing. The radio link is sub-GHz and designed to pass through typical walls and floors, but range is improved with a reasonably clear path to the hallway diffuser. Avoid fixing directly to large metal surfaces which can screen radio signals.

Wipe the wall area clean and dry so the adhesive pad bonds well, or have suitable wall plugs and screws ready if you prefer to use the fixing plate. Confirm the fan is powered and that you can stand at the diffuser to access its buttons for pairing.

The 2-Way Switch is battery powered and supplied with an adhesive pad and a removable fixing plate for screw mounting.

Limitations And Good Practice

Keep the switch out of bathrooms and away from frequent splashes. Mount it at a sensible height for all users, and where it will not be pressed accidentally. If you later relocate the switch, remove the old adhesive carefully to avoid wall damage, then re-pair the switch if communication drops.

Step-By-Step Installation

1. Prepare The Switch: If you will screw-mount, release the fixing plate by inserting a small flat screwdriver into the side recess and gently levering until each lug releases; this also exposes the battery compartment. Check the coin cell is seated. Reassemble the switch body and plate ready for fixing. If you will use the adhesive pad, leave the liner in place for now. The switch uses a CR2032 cell with an expected service life of up to 10 years under normal use.
   
   

2. Fix The Switch To The Wall: For adhesive mounting, peel the liner and press the switch firmly to the prepared surface for several seconds. For screw mounting, offer up the fixing plate, mark and drill pilot holes, fit suitable plugs and screws (not supplied), then clip the switch body back to the plate until it clicks.
   
   

3. Put The Fan Into Binding Mode: Stand at the hallway diffuser. With the fan powered, if a start-up sequence is showing, press the down button once to exit. Press and hold the up and down buttons together for about 20–30 seconds (around 25 seconds is ideal) until a single horizontal bar flashes, then press down to enter binding. The display will show a flashing b for five minutes while it listens for accessories. A solid P on the display denotes purge/boost; a flashing b denotes binding mode.
   
   

4. Bind The Switch: Press and hold the Boost button on the 2-Way Switch. The switch LED will flash green twice to confirm a successful bind. To prove the link, press Boost once: the LED should show green and the fan should run at maximum with P visible on the diffuser display. If the LED shows red, repeat the step while the b is flashing on the diffuser.
   
   

5. Finish And Tidy: Exit binding by waiting for the five-minute window to close or by repeating the diffuser button-hold to leave pairing. Press Normal on the switch to return the fan to its commissioned setting. Wipe away pencil marks and keep a note of the installation location and date for your records. On this platform, “Normal” returns the unit to the programmed airflow and temperature logic set at the diffuser, and “Boost (Purge)” drives the fan to maximum for a timed period before the unit automatically reverts to Normal.
   
   

Maintenance

Keep the switch face clean with a soft, dry cloth. Replace the CR2032 battery when presses no longer produce a green LED or when response becomes intermittent. To change the cell, release the fixing plate as above, open the battery compartment on the rear, fit a fresh CR2032 observing polarity, and reassemble until it clicks.

After a battery change the switch normally retains its pairing; if it does not, repeat the binding steps. The manufacturer quotes an expected battery life up to 10 years under typical use, so frequent changes should not be necessary.

Troubleshooting

If the fan does not respond to Boost and the switch LED shows red, the switch is not paired; reopen binding mode at the diffuser and repeat the binding step close to the diffuser.

If the LED shows green but airflow does not increase, confirm the fan is powered, not already in boost, and that the duct and diffuser are unobstructed; also check that you are within radio range and not mounted on a large metal surface.

If the switch appears dead, replace the CR2032 cell and try again.

If the diffuser display shows both b and P at once, the unit is in binding mode and purge simultaneously, which is expected when testing during pairing.

For persistent communication issues, move the switch a little nearer the diffuser and re-test.

Q) What is the Nuaire Drimaster ECO 2-Way Boost Switch (DRI-ECO-2S) and what does it do?

A) The Nuaire Drimaster ECO 2-Way Boost Switch (DRI-ECO-2S) is a compact, battery-powered wall control that wirelessly commands your RF-enabled Drimaster ECO Positive Input Ventilation system—most commonly the DRI-ECO-LINK-HC—to run either at its normal, commissioned background rate or at a timed, high-speed boost. Pressing Boost triggers a temporary uplift to clear moisture, odours and stuffiness rapidly; when the boost period ends, the fan automatically returns to the pre-set background rate without you needing to touch the settings at the diffuser. Because the Nuaire Drimaster ECO 2-Way Boost Switch uses the same “Hall Control” platform as the fan, you pair it at the hallway diffuser in seconds and avoid any loft access or new cabling. The low-profile enclosure surface-mounts with an adhesive pad or a small fixing plate, so you can place it exactly where it will be used day to day—near a kitchen doorway, by a utility room or on a landing—making whole-home ventilation genuinely convenient for occupants.

Q) Which systems is the Nuaire Drimaster ECO 2-Way Boost Switch compatible with and where should it be used in the home?

A) The Nuaire Drimaster ECO 2-Way Boost Switch is intended for RF-enabled Hall Control Drimaster ECO units and is most often paired with the DRI-ECO-LINK-HC. Once bound, the switch communicates with the fan over a secure sub-GHz radio link designed to work reliably through typical internal walls and floors. As a domestic accessory, it suits any home that uses Positive Input Ventilation for condensation control and background air-quality improvement, giving occupants simple, fingertip control of temporary boost without entering the loft or changing commissioning. You can mount the switch in kitchens (away from hobs), utility areas, landings and bedrooms; avoid wet zones and frequent splash areas, and keep it out of direct heat and strong sunlight. Because it is wireless and battery powered, the Nuaire Drimaster ECO 2-Way Boost Switch is particularly helpful in retrofits and managed housing, where adding new control wiring would be disruptive, and in busy households that want quick, predictable boosts during showers, laundry and cooking.

Q) How do I install and pair the Nuaire Drimaster ECO 2-Way Boost Switch with my Drimaster ECO fan?

A) Installation and pairing are quick. Decide on a convenient location, wipe the surface clean, and either use the supplied adhesive pad for a cable-free mount or screw the fixing plate to the wall and clip on the body. With the fan powered, stand at the hallway diffuser and enter accessory binding from the Hall Control: if a start-up sequence is showing, press Down once to exit, then press and hold Up and Down together for roughly 20–30 seconds until a single horizontal bar flashes; press Down again to open the five-minute binding window, indicated by a flashing “b”. Press and hold Boost on the Nuaire Drimaster ECO 2-Way Boost Switch; the switch LED will flash green twice to confirm pairing. Prove the link by pressing Boost once—“P” will show on the diffuser while the fan runs at maximum (purge). Press Normal to return to the commissioned background rate. If binding fails, repeat the process closer to the diffuser and ensure the battery is seated correctly.

Q) Where should I position the Nuaire Drimaster ECO 2-Way Boost Switch for the best performance and user experience?

A) For dependable radio communication and everyday convenience, mount the Nuaire Drimaster ECO 2-Way Boost Switch where it will be used most, with a reasonably clear path to the hallway diffuser. Typical locations include beside a kitchen entrance, near a utility room, or on an upstairs landing for bathrooms and en-suites. Fit it at a sensible height that all users can reach, but away from corners where fingers might brush it accidentally. Avoid fixing directly to large metal surfaces (which can screen radio signals), above radiators or near ovens and hobs, and do not place it in bathroom splash zones; hallways outside wet rooms are ideal. The slim, low-profile design is intended to blend with décor, and the adhesive pad allows clean positioning on smooth, dry substrates. If you change your mind later, the control can be relocated: gently remove the pad, fit a fresh one, re-site the switch and, if communication drops, repeat the simple binding step at the diffuser.

Q) How does Boost work on the Nuaire Drimaster ECO 2-Way Boost Switch, and can the duration be adjusted?

A) Pressing Boost on the Nuaire Drimaster ECO 2-Way Boost Switch commands the Drimaster ECO fan to its maximum purge airflow for a timed period. This rapid uplift is designed to clear short-lived humidity and odours—showers, cooking, laundry—far more quickly than background ventilation alone, after which the system automatically returns to its commissioned setting without any user intervention. The boost duration and behaviour are governed by the fan’s Hall Control commissioning, not the wall switch itself; your installer can adjust the boost timer and temperature response at the diffuser to match the home’s size and habits. Because the 2-Way Boost Switch keeps background rates low and only adds airflow when needed, it supports an energy-aware strategy: you get swift removal of peaks without running the fan at high speed all day. If you also use local room extracts (bathroom or cooker hood), the boost complements rather than replaces them, providing whole-home dilution alongside point extraction.

Q) What are the energy and comfort advantages of using the Nuaire Drimaster ECO 2-Way Boost Switch with PIV?

A) The Nuaire Drimaster ECO 2-Way Boost Switch encourages best-practice use of Positive Input Ventilation: set the fan to the lowest background rate that still controls condensation, then add short, targeted boosts only when activities drive humidity or odours up. This approach keeps running costs modest—PIV fans draw very little power at background—while ensuring that busy periods get the airflow they need for comfort. Because you can trigger boost from anywhere in the home without entering the loft, occupants are more likely to use it correctly after showers, during laundry or when cooking, which helps prevent steamed mirrors, window condensation and musty smells. The switch integrates with the fan’s temperature logic at the diffuser, so boost will still respect hot-loft standbys and comfort protections. In practice, the result is a fresher-smelling home, drier surfaces and fewer mould-friendly conditions, achieved with a simple, intuitive control that fits occupants’ daily routines.

Q) What maintenance does the Nuaire Drimaster ECO 2-Way Boost Switch need and how long does the battery last?

A) The Nuaire Drimaster ECO 2-Way Boost Switch is designed for minimal upkeep. Keep the face clean with a soft, dry cloth and avoid solvents. The control uses a standard CR2032 coin cell; under typical domestic use the expected service life is up to 10 years. When the battery weakens, button presses may no longer produce a green LED or the fan may not respond reliably; release the switch from its fixing plate, open the rear battery compartment, install a fresh CR2032 observing polarity, and reassemble until it clicks. Pairing is normally retained through a battery change; if communication is lost, simply reopen the fan’s binding window at the diffuser and press Boost to re-pair. Dispose of used coin cells responsibly and keep new and spent batteries away from children and pets. Because the switch is wireless, there are no cables to inspect, and the adhesive mounting pad can be replaced easily if you relocate the unit during redecoration.

Q) Are there any limitations or common pitfalls to avoid with the Nuaire Drimaster ECO 2-Way Boost Switch?

A) A few simple rules ensure trouble-free use. Only one wall-switch type should be paired to a Drimaster ECO system at a time—use either a 2-Way or a 4-Way, not multiples of the same type—so decide which interface suits the household. Mount the Nuaire Drimaster ECO 2-Way Boost Switch outside bathroom splash zones and away from direct heat or strong sunlight, and avoid fixing directly to large metal surfaces that can attenuate radio signals. If you move the switch, remove old adhesive carefully, fit a new pad and re-pair if communication drops. Remember that the wall switch does not change the fan’s commissioning; boost duration and temperature logic are set at the diffuser, so ask your installer to adjust those if the uplift feels too short or too long. Finally, if presses show a red LED or the fan does not respond, re-enter binding at the diffuser and pair again—most issues are resolved by a quick rebind and a fresh CR2032 cell.
