SAVECair touchscreen

Full-colour touchscreen integrated in the unit's front door. Fan speed selection, week schedule, alarm history, filter status, sensor inputs, commissioning wizard. The default operating interface — no separate panel required.

SAVE CONNECT (WiFi)

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.

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.

CD4 external control panel

Optional wired wall-mounted control panel for installations where the integrated SAVECair touchscreen on the unit isn't at a convenient location. Same control set, repeated at a wall position elsewhere in the home.

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 SAVECair 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.

VTR 300/B plant unit

Double-skinned panels, white painted sheet steel construction. Wall-mounted vertically on supplied bracket. Left-hand or right-hand duct configuration (separate SKUs — confirm at order). SAVECair touchscreen integrated in the front door.

Rotary heat exchanger

Variable-speed rotating exchanger with moisture transfer. Approximately 14 kg, removable from the front for cleaning every 3 years (or sooner if the 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, 50% less energy than equivalent AC motors. Lifetime-lubricated bearings, maintenance-free.

Four duct spigots (top-connected)

All four ducts (intake, exhaust, supply, extract) connect on the top of the unit. Compatible with standard EU residential MVHR duct sizes — confirm exact spigot diameter at design stage. Cooker hood inlet is also on top.

F7 + M5 filter set

Factory-fitted F7 (ISO ePM1 60%) supply filter and M5 (ISO ePM10 60%) extract filter. Tool-free replacement via the front hatch. G3 alternative available for smaller-particle environments where F7 isn't required.

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.

Cooker hood bypass

Dedicated kitchen extract inlet on top of the unit. Cooker-hood air bypasses the heat exchanger entirely — no grease accumulation on the rotor, no service disruption from cooking residue.

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 SAVECair touchscreen 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 M5 extract filters, accessed by opening the front hatch. Tool-free replacement. The SAVECair touchscreen 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 front for cleaning every 3 years (or sooner if airflow performance drops). Approximately 14 kg — two-person lift recommended. Wash in hot soapy water (no ammonia detergents).

Drive belt — replaceable

A rubber drive belt rotates the heat exchanger via the rotor motor. The SAVECair 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 self-maintain, CleverBloom offers an annual visit covering filter change, rotor inspection, flow rate verification with anemometer, and any sensor recalibration. Specify at handover.
