SAVE Touch panel (wall or unit)

Full-colour touchscreen, user-friendly interface. Connects via the side connection board. Mount on the unit if it's accessible, or wire to a convenient wall position elsewhere in the home — ideal when the plant lives in the loft. Multiple panels can be daisy-chained for larger installs.

SAVE CONNECT (WiFi)

Optional WiFi accessory module for remote access via the SAVE Connect mobile app (iOS and Android) or the homesolutions.systemair.com web portal. Local or remote control, no LAN cabling required, links to Amazon Alexa and Google Home for voice control.

Modbus RS-485

Standard on every unit. Direct integration with home automation and BMS systems via Modbus protocol — useful for commercial installs (offices, classrooms) where ventilation needs to integrate with heating and lighting control.

Built-in humidity sensor

Standard — fitted in the extract air chamber from factory. Demand control is enabled out of the box: the unit ramps fan speed when extract RH rises (shower, cooking, drying laundry). No optional sensor needed for this.

Optional CO₂ sensor

Add-on CO₂ sensor for occupancy-driven control. Useful for home offices, classrooms, and bedrooms where humidity-only control isn't enough. Wires directly into the connection board on the side of the unit.

Week schedule

Built into the SAVE Touch controller — set up to two airflow time periods per day across each day of the week. Useful for homes with predictable occupancy patterns (away during working hours, busier in evenings).

Boost / refresh mode

Timed boost at high speed for clearing odours after cooking, fast air change after gatherings, or post-shower humidity. Returns to scheduled airflow automatically. Triggered via touchscreen, app, or external switch.

Automatic summer mode

When indoor temperature exceeds the set threshold and outdoor air is cooler, the unit automatically switches to summer operation — cooling recovery without active heat exchange. Returns to winter operation as conditions change.

VSR 300 plant unit

Double-skinned panels, fully insulated cabinet. Designed to lie horizontally — sits on a loft floor, in a ceiling void, or on a basement plinth. Compact footprint suits tight roof spaces. Left or right hand variants — confirm at order.

Rotary heat exchanger

Variable-speed rotating exchanger with moisture transfer. Removable for cleaning every 3 years (or sooner if airflow performance drops). Drive belt is the only consumable hardware in the rotor mechanism.

EC RadiCal fans

Two RadiCal impeller fans with EC (electronically commutated) motors. Modern brushless DC technology — quiet operation, low specific fan power (0.35 Wh/m³ Passivhaus certified), 50% less energy than equivalent AC motors. Lifetime-lubricated bearings, maintenance-free.

Four side-connected duct spigots

All four ducts (intake, exhaust, supply, extract) connect on the side of the unit — the defining VSR architecture. Allows ductwork to run horizontally from the unit into a flat ceiling void or loft, without the vertical clearance that top-connected units (like the VTR series) need.

F7 + G4 filter set

F7 (ISO ePM1 50%) supply filter and G4 (ISO Coarse 60%) extract filter per the Passivhaus certificate. Tool-free replacement. Higher-grade alternatives available for urban or pollen-heavy environments.

Integrated 1670 W reheater

Electric reheater downstream of the rotor — maintains supply air ≥16.5°C even at outdoor temperatures of -10°C (Passivhaus comfort criterion). Thermostatically controlled, only draws power when needed.

Inspection hatches both sides

Service access from either side of the unit — a meaningful advantage when the plant lives in a tight loft or basement plinth. Means the rotor, fans, and filters can be reached without dismantling adjacent ductwork.

SAVE CONNECT cloud module

Optional WiFi accessory for remote control via the SAVE Connect mobile app or web portal. Plugs into the connection board on the side of the unit. Required for app control, not needed for local SAVE Touch panel operation.

2-year manufacturer warranty

Systemair provides a 2-year manufacturer warranty on the unit as standard. Built to Eurovent certification and ErP compliance with global service network. Mature platform — Systemair has been making rotary MVHR since 1974.

Filter change every 6–12 months

F7 supply and G4 extract filters, accessed via the side inspection hatches. Tool-free replacement. The SAVE Touch panel flags when change is due (default 12 months, adjustable 3–15 months). Filter sets typically £25–40 from UK distributors.

Removable rotary exchanger

The heat exchanger lifts out from the side for cleaning every 3 years (or sooner if airflow performance drops). Wash in hot soapy water (no ammonia detergents). Both-sided access makes servicing in loft spaces significantly easier than top-only-access units.

Drive belt — replaceable

A rubber drive belt rotates the heat exchanger via the rotor motor. The SAVE Touch controller flags an alarm if the belt slips or breaks. Replacement is straightforward — Systemair supplies the belt as a service spare. Plan for one belt change in a 10-year service life.

Ductwork — no scheduled maintenance

Once correctly installed and balanced, modern smooth-bore plastic ductwork runs maintenance-free. Periodic visual inspection of intake/exhaust grilles for leaf or debris accumulation is the only routine task.

Optional CleverBloom service plan

For homeowners who don't want to climb into the loft annually, CleverBloom offers a yearly visit covering filter change, rotor inspection, flow rate verification with anemometer, and any sensor recalibration. Specify at handover.
