Most people install a single room heat recovery unit, get it running, and leave it on the same setting permanently. It works, sure. But you’re missing out on a good chunk of what these units can actually do.
Modern Wi-Fi enabled single room heat recovery units let you schedule different speeds, modes and run times through a free smartphone app. You can set the unit to run on a low, quiet speed overnight so it doesn’t disturb your sleep, then bump it up to a higher speed during the day when cooking or showering produces more moisture. You can also switch between heat recovery mode in winter and standard ventilation in warmer months, all on a timer.
If you’ve got a unit like the Vents TwinFresh Atmo or TwinFresh Style with Wi-Fi, the whole process takes about two minutes once you’re connected. Below, we’ll walk through exactly how to set up schedules, what settings you can adjust, and a few practical tips that make a real difference in how well your unit performs in an Irish home.
How Does Scheduling Work on Wi-Fi Enabled Units?
Scheduling on a single room heat recovery unit works through the manufacturer’s app on your phone. For units in the Vents TwinFresh range sold by VentSolve, you’ll use the Vents TwinFresh app, which is free on both Android and iOS.
Once your unit is connected to your home Wi-Fi network, open the app and find your ventilation unit in the device list. From there, tap on the timer or schedule option (usually labelled “More” then “Timer”) and hit “Add New Timer.” That’s your starting point for building out a custom schedule.
The app lets you pick specific days of the week, set the time you want the schedule to kick in, choose the operating mode, and select the fan speed. So if you want the unit running in heat recovery mode on speed one every night at 8pm from Monday to Sunday, you set that up in about thirty seconds. You can add multiple timers too, so a morning schedule and an evening schedule can run side by side without any hassle.
What Settings Can You Schedule?
There are three main things you can control through the app’s scheduling feature on most Wi-Fi enabled single room heat recovery units.
First is the operating mode. You can choose between heat recovery mode (which recaptures warmth from outgoing stale air and transfers it to fresh incoming air), ventilation mode (standard airflow without heat exchange), and supply mode (which brings in outside air only). For most Irish homes during the colder months, heat recovery mode is the best option because it keeps fresh air flowing without letting your hard-won heat escape through the wall.
Second is fan speed. Most units offer three speed settings. Speed one is the quietest and uses the least energy. Speed two is a good middle ground for daytime use. Speed three is your boost mode for high-moisture situations like after a shower or when the kitchen is full of steam.
Third is timing. You pick the exact time each schedule activates and which days of the week it applies to. Some homeowners set it for every day. Others have a different schedule for weekdays and weekends, which makes sense if your routine changes at the weekend.
Why Schedule Different Speeds at Different Times?
Running your single room heat recovery unit at full speed around the clock costs more in electricity and creates more noise than you need. The units are quiet to begin with (the TwinFresh Atmo Mini runs at just 23 dB at three metres on its lowest setting), but in a bedroom at night, even small differences in noise level matter.
Setting the unit to speed one in heat recovery mode from around 8pm to 7am keeps the air fresh without any noticeable hum. During the day, you can schedule speed two or three to deal with condensation from cooking, showering and drying clothes, which is where most of the indoor moisture comes from in Irish homes.
This approach also saves energy. These units already cost very little to run (roughly €2 per year on the lowest speed), but smart scheduling means you’re only using higher speeds when they’re actually needed. Over time, that adds up.
Step-by-Step Guide to Setting Up a Schedule
Here’s how to create your first schedule on a Vents TwinFresh unit through the app. Connect your phone to the same Wi-Fi network as the unit. Open the Vents TwinFresh app and select your unit from the device list.
Tap “More” and then “Timer.” Hit “Add New Timer” to create a new schedule entry. Select which days of the week you want this schedule to apply (you can pick all seven or just specific days).
Choose the operating mode. For winter, heat recovery is your best bet. Select your preferred speed. For a nighttime schedule, speed one keeps things quiet. Set the activation time. For an evening schedule, something like 8pm works well for most households.
Save the timer, and that’s it. The unit will now automatically switch to those settings at the time you’ve chosen. You can add as many timers as you like, so don’t be afraid to create separate schedules for morning, daytime and night.
Common Mistakes to Avoid When Scheduling
One thing people often get wrong is leaving the unit in ventilation mode all winter instead of heat recovery mode. In Ireland’s cool, damp weather, heat recovery mode saves you money on heating by warming the incoming fresh air with the outgoing stale air. Ventilation mode doesn’t do this, so you’re essentially pumping cold air into the room.
Another mistake is setting the unit too high at night and then wondering why the bedroom feels draughty. Speed one at night is almost always enough for a single room. If you’re still getting condensation on windows in the morning, bump it up to speed two, but try the lower setting first.
Finally, make sure your phone’s app is connected properly and that your Wi-Fi signal reaches the unit. If the unit is in a back bedroom with a weak Wi-Fi signal, the schedule might not update reliably. A Wi-Fi extender can solve that problem easily enough.
When Should You Call a Professional Instead?
Scheduling through the app is something any homeowner can do. But if the unit itself isn’t performing well (poor airflow, unusual noise, or condensation not improving), that’s a different story. A unit that’s been incorrectly positioned or installed won’t fix itself no matter how clever your schedule is.
VentSolve’s in-house team of certified technicians can assess whether your unit is in the right spot, whether the duct is properly sealed, and whether the unit is sized correctly for the room. They respond to enquiries within 2-4 hours and can usually complete a single room installation or adjustment in one visit. If your unit needs servicing or a filter change, that’s also worth getting done professionally at least once a year to keep the heat exchanger running efficiently, as per the manufacturer’s guidelines on the unit’s ceramic heat exchanger, which can recover up to 81% of outgoing heat.
Getting your scheduling right is one of the easiest upgrades you can make to a single room heat recovery unit without spending a cent. A few minutes with the app and you’ll have better air, less condensation and quieter nights.

FAQs
Q1: Can I schedule my single room heat recovery unit from my phone?
A: Yes, if your unit has Wi-Fi (like the Vents TwinFresh Atmo or Style range), you can schedule speeds, modes and timing through the free Vents TwinFresh app. The app is available on both Android and iOS devices.
Q2: What is heat recovery mode on a single room unit?
A: Heat recovery mode captures warmth from the stale air being extracted and uses it to preheat the fresh air coming in from outside. This means you get fresh air without losing heat, which is particularly useful during Ireland’s colder months.
Q3: How much does it cost to run a single room heat recovery unit?
A: These units are very energy efficient. Running on the lowest speed, a unit like the TwinFresh Atmo Mini costs roughly €2 per year in electricity. Higher speeds cost more, but smart scheduling keeps overall running costs low.
Q4: Should I leave my single room heat recovery unit running all the time?
A: Yes, these units are designed to run continuously to maintain air quality and prevent condensation. Scheduling allows you to lower the speed at night for quiet operation and increase it during the day when moisture levels are higher.
Q5: What speed should I set my unit to at night?
A: Speed one is usually enough for nighttime use. At this setting, units like the TwinFresh Atmo Mini produce just 23 dB of noise at three metres, which is barely noticeable. If condensation persists, try speed two.
Q6: Can I set different schedules for weekdays and weekends?
A: Yes, the app allows you to select specific days for each timer. You can create one schedule for Monday to Friday and a different one for Saturday and Sunday to match your household routine.
