Air Velocity Profile

A diagram illustrates the air velocity profile at various distances from the unit for AD 200 A/E and AD 200 W models, showing velocities ranging from 10.5 m/s at 0.0m to 3.0 m/s at 2.5m.

Dimensions

Detailed diagrams show the physical dimensions for the Ambient/Electric and Water models. Key dimensions include lengths of 1020mm, 1530mm, and 1960mm, with depths and heights specified. Water models feature DN15 (1/2") internal thread connections.

Mounting and Installation

Mounting: Thermozone AD200 units can be permanently mounted on walls or ceilings using threaded drop rods and suspension kits, or integrated into false ceilings. Mounting is horizontal with the air outlet directed downwards. A minimum distance of 50mm from the outlet to flammable material is required. Mounting brackets are included, and their distance is adjustable. 2-meter units require three fixing points. For optimal performance, the air curtain should cover the full width of the opening and be positioned as close to it as possible. Multiple units can be installed adjacent to each other for wider openings.

Connection AD 200E: The appliance must be isolated by a triple pole switch with a minimum 3mm breaking gap. Connections are made via knock-outs on the unit's top side. Maximum cable size for the supply terminal block is 16 mm², and for the control terminal block is 4 mm². For units with electrical heating, separate power and control supplies are typically recommended, though common supplies may be used for smaller units (current below 16 A). AD220E models have heating elements divided across two separate supplies.

Connection AD 200W: The control cable connects via a knock-out on the top right side (when viewed from inside). Water heating coil connections (DN15, 1/2" internal thread) are located on the top left side.

Minimum Mounting Distances: A table specifies minimum mounting distances 'A' for various models, ranging from 50mm to 100mm depending on the unit type.

False Ceiling Mounting: Requires a false ceiling grille and adequate space for service/inspection hatches.

Mounting with Suspension Kit (Extra)

Optional suspension kits (ADPK1, ADPF1) are available for mounting the air curtains. Threaded bars and M8 nuts are not included with these kits.

Complete Control Kits

Various control kits are available to manage airflow and heating based on different environmental conditions:

Ambient

• Manual Control: CB30N control box offers 3-step airflow control.

Electric

• Level 1: Manual airflow control with a 2-step room thermostat for heat output. Kit CK01E includes CB32N control box and RTI2 thermostat.
• Level 2: Automatic control based on door opening and room temperature. Fan speed adjusts dynamically. Kit CK02E includes CB32N control box, MDC magnetic door contact with time delay, and RTI2 thermostat.
• Level 3: Advanced automatic control considering door status, outdoor temperature, and room temperature. Utilizes a microprocessing regulator. Kit CK03 includes ADEA regulator (with built-in sensor), ADEAIS indoor sensor, and ADEAEB control board.

Water

• Level 1: Manual airflow control with heat output managed by an actuator/valve via a room thermostat. Kit CK01W includes CB30N control box and T10 room thermostat. Requires separate valve/actuator sets (e.g., VR20, VR25, SD20, TVV20, TVV25).
• Level 2: Automatic control based on door opening and room temperature. Kit CK02W includes CB30N control box, MDC magnetic door contact with time delay, and RTI2 thermostat. Requires separate valve/actuator sets.
• Level 3: Advanced automatic control considering door status, outdoor temperature, and room temperature. Kit CK03 includes ADEA regulator (with built-in sensor), ADEAIS indoor sensor, and ADEAEB control board. Requires separate valve/actuator sets.

Output Charts (Water)

Performance data for water-heated models is presented in tables detailing output (kW) and water flow (l/s) under various conditions:

• Incoming/Outgoing Water Temperature 90/70 °C
• Incoming/Outgoing Water Temperature 80/60 °C
• Incoming/Outgoing Water Temperature 60/50 °C
• Incoming/Outgoing Water Temperature 60/40 °C

These charts specify performance based on fan position (max/min), airflow (m³/h), and incoming air temperature (+15 °C or +20 °C).

Water Pressure Drop Charts

Graphical data is provided for water pressure drop:

• Water pressure drop over watercoil AD 200W: Illustrates pressure drop (kPa/bar) versus water flow (m³/h or l/s) for AD210W, AD215W, and AD220W models.
• Water pressure drop over controls and valves: Shows pressure drop (kPa/bar) versus water flow (m³/h or l/s) for different control and valve combinations (VR20, TVVX20, VR25, TW25).

Pressure drop is calculated for an average water temperature of 70 °C (PVV 80/60), with a factor K provided for adjustments at other temperatures.

Wiring Diagrams

Wiring diagrams are included for various control configurations: Ambient control options for AD 200 A, compact model for AD 210 C, and electric control options (Level 1, 2, 3) for AD 200 E, as well as water control options (Level 1, 2, 3) for AD 200 W.
