LVDV - CEILING-MOUNTED AIR HEATERS FOR HOT WATER
LVDV ceiling-mounted fans are used for heating entrances, warehouses, industrial premises, workshops, sports halls, garages and shops. Due to its low overall height the LVDV can be built into the ceiling. The fans are designed for 230V~ power supply, which makes the installation very simple. The fans have a low sound level and offer reliable operation. • Three sizes and two models • Available with built-in control equipment for sensor control or for external 0...10V:s control signal • The hinged front panel makes the coil and fan easily accessible for inspection and cleaning • Suspended from the ceiling – leaves the wall surface clear • Low overall height – can be built into the ceiling • Simple 230V~ installation • Two fan speeds as standard Design The casing is made of galvanized sheet steel painted white. The coil has copper tubes and aluminium fins. The ball-bearing mounted fan with overheating protection has a low sound level and offers reliable operation. The front panel is hinged, which makes it easy to open for inspecting the coil and fan. The LVDV is available in two models: LVDV-aa-1 and LVDV-aa-0.
CONTROL Built-in control equipment LVDV-aa-1 Fan heater with built-in control equipment for external sensor and setpoint adjustment. Can also be controlled by an external 0...10V control signal. See pages 4 and 5. External control equipment LVDV-aa-0 Fan heater for external control equipment. Has two fanspeeds. See pages 6 and 7.
Capacity Pages 8 and 9 give examples of capacities for each size. Installation Can be installed directly on the ceiling or suspended from hangers.
APPROVALS The AIR HEATERS are manufactured in accordance with: LVD Directive: EN 60355-1 and EN 60335-2-30 EMC Directive: EN 61000-6-2 and EN 61000-6-3 EMF Directive: EN 62233

LVDV-aa-1 FAN HEATER FOR HOT WATER WITH BUILT-IN CONTROL EQUIPMENT FOR FAN AND WATER CONTROL The LVDV-aa-1 with built-in control equipment gives a simple installation due to fewer cable runs, etc. This, in turn, lowers the installation cost and reduces the risk of incorrect connections. The control equipment is suitable for an external temperature sensor and setpoint adjuster or external 0...10V control signal. Model –aa-1 The LVDV-aa-1 has built-in control equipment with electronic thermostat that starts/stops the fan and opens/ shuts off the water flow. The thermostat controls automatically in three steps: Step 1 – Fan runs only at low speed, without hot water. This function puts to use of the warm air stored under the ceiling, which results in efficient energy utilization and saves money. Step 2 – The fan runs at low speed and the hot water valve opens. Step 3 - The fan runs at high speed and the hot water valve opens. Control
Installation The LVDV-aa-1 is mounted directly on the ceiling or on hangers.
The LVDV-aa-1 must be supplemented with an external room sensor and setpoint adjuster. See the next page for examples. The LVDV-a can also be controlled by an external 0...10V control signal. A LVDV-aa-1 with sensor connected can carry out slave control of an unlimited number of LVDV-aa-1 units and/or our wall-mounted type AW-a AIR HEATERS. The slavecontrolled units then need no sensors and receive their control signals from the LVDV-aa-1 with sensor. See next page for sensors. Accessories See next page for sensors suitable for the LVDV-aa-1.
PROJECT DESIGN/ORDERING DESCRIPTIVE TEXT - LVDV-aa-1 Ceiling-mounted fan heater for hot water, Fläkt Woods type LVDV-aa-1, with casing of galvanized sheet steel, painted white. Water coils with copper tubes and aluminium fins. The hinged front panel makes the coil and fan easily accessible for inspection and cleaning. Built-in control equipment for fan and water control. Setpoint adjustment is carried out externally. Accessories such as room sensor, setpoint adjuster, filter and extension duct must be ordered separately.
