Product Overview

This Kit Includes: 1 × Toshiba U00251SY-E Air-to-Air Heat Exchanger – 250–200–150–100 m³/h Airflow | 80.5% Temperature Efficiency | 76.0% Enthalpy Efficiency | 220-240V~50Hz 1 × Toshiba RBC-AMSU52-E Wired Controller The Toshiba U00251SY-E is a compact, efficient air-to-air heat exchanger engineered to reclaim energy from exhaust air and pre-condition incoming fresh air. Designed for commercial, industrial, hospitality and residential ventilation systems, it significantly reduces heating and cooling loads on connected HVAC equipment. With excellent temperature and enthalpy exchange performance, low sound levels and a slim, easy-install chassis, this model is ideal for improving indoor air quality while reducing running costs. Key Product Features: Operating temperature range: -15°C to +50°C (unit) Outdoor operating range: -20°C to +52°C Return-air humidity tolerance: 5%–80% RH 250–200–150–100 m³/h multi-step airflow settings External static pressure range: 75-53-30-15 Pa Very low sound pressure levels: 28-27-24-20 dB(A) High

temperature exchange efficiency: 80.5% Enthalpy recovery efficiency: 76.0% Slim, compact chassis for easy installation Compatible with RBC-AMSU52-E premium wired controller Optional CO₂/PM air-quality sensor for automated demand-controlled ventilation Supports duct connection: 150 mm × 2 (supply/return) Designed for integration with Toshiba Digital Inverter & DX coil systems Ideal for offices, shops, schools, hotels, clinics and energy-efficient buildings Technical Specifications: Model: U00251SY-E Operating Range (Unit): -15°C to 50°C / ≤80% RH Operating Range (Outdoor Air): -20°C to 52°C / ≤80% RH Operating Range (Return Air): 5°C to 40°C / ≤80% RH Airflow (Extra High / High / Medium / Low): 250 / 200 / 150 / 100 m³/h External Static Pressure: 75 / 53 / 30 / 15 Pa Sound Pressure (E-H-M-L): 28 / 27 / 24 / 20 dB(A) Temperature Exchange Efficiency: 80.5% Enthalpy Exchange Efficiency: 76.0% Dimensions (HxWxD): 278

× 735 × 778 mm Weight: 29 kg Duct Nominal Diameter: 150 mm × 2 (supply/return) Suggested Power Supply: 220–240V~50Hz & 3(10) A 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.
