Dimensions (H × W × D): 305 × 880 × 880 mm Weight: 40 kg Duct Nominal Diameter: 150 × 2 / 150 × 2 mm Suggested Power Supply: 220/240V~50Hz & 6(16)A Accessories (Compatible VN Range): CO₂/PM multifunction sensor (TCB-SFMCA1V-E) Control interface for VN-U00151/U01001SY-E (RBC-VNMC-HE1) Heater kits (100 mm / 150 mm / 200 mm / 250 mm) Weatherproof housings for outdoor mounting High-performance filters (EPM1 55%) depending on model size Options: Accessory Type Model / Part Code Description / Purpose Wired Controllers RBC‑AMSU52-E Premium remote controller with 7-day timer, multi-language display, refrigerant-leak indication, energy-save settings — ideal for daily control of ventilation. NRC-01HE Basic remote controller for ON/OFF and fan-speed control when only a ventilation unit is installed. Interface / Control Leads RBC‑VNL1 Interface / CN-connector leads Used for linking the heat exchanger to controllers, external inputs, or building-management
systems (BMS), enabling external ON/OFF, damper control, and central control functions. Pre-heater / Heater Kits (for cold-climate or pre-heating incoming air) RBC‑VNMH1-PE (100 mm) Adds a 1 kW heater unit suitable for small heat exchangers — useful if fresh air intake requires tempering. RBC‑VNMH2-PE (150 mm) Heater kit for mid-range models (e.g. RBC‑VNMH3-PE (200 mm) Higher-capacity heater kit for larger ventilation units (e.g. RBC‑VNMH4-PE (250 mm) For large units (800 m³/h and above) — delivers stronger fresh-air heating capacity when needed. High-Performance Air Filters (for improved air quality) Filter panels (EPM1 55 %) — various part codes depending on VN size Provide enhanced filtration (PM / dust / pollen) — important for offices, clinics, schools, or any clean-air requirement. Optional CO₂ / PM Sensor Module TCB-SFMCA1V-E When fitted, enables ventilation fan-speed control based on real-time indoor air-quality — improving efficiency
and compliance to air-quality standards (available from 2023 updates) Weatherproof/Outdoor Housings Various “Outdoor Housing” kits (size dependent) If the heat exchanger is installed outdoors or in partially exposed areas — helps protect the unit from weather, ensuring durability and compliance in exposed installations. External Input / ON–OFF Adapter NRB-1HE Remote ON/OFF Adapter Allows the heat-exchanger to be controlled by external 0-V contact closure or building-management systems (BMS) instead of just the remote controller. CN Connector Kits & Leads (for wiring/branching) Multiple CN-series connectors (CN610, CN704, CN705, CN706, CN80 etc.) Used to connect multiple VN units or interface them with controllers/ BMS; required for “group control” or multi-unit installations. These air conditioning units must be installed by an F-Gas qualified engineer. We can install the unit for you using our F-Gas Certified Engineers. Please note if you do not select our
installation service we will not ship the unit until we have obtained evidence from you that you will have the unit installed by an F-Gas qualified engineer. This is a requirement of the Article 11 (5) EC/517/2014 on fluorinated greenhouse gases and The Fluorinated Greenhouse Gases Regulations 2015.
