1 LVD Unit Heater

2 Unit heater with accessories The type LVDV fan-assisted unit heaters are designed for space heating in shop entrances, lobbies, doorways, warehouses and workshops, garages and similar premises. The unit is designed for mounting beneath a ceiling. Hot water is used as the heating medium. All units comply with EU requirements on machinery safety, 91/368/EEC. The fan-assisted unit heater: is made of galvanised sheet steel, painted white. has low overall height, short or long throw can thus be fitted in premises with various ceiling heights can be fitted with an air discharge device to increase the throw. is easy to clean; simple to service. can easily be mounted against the ceiling or suspended from it. The LVDV incorporates a quiet fan impeller and flange motor to IEC Publ. 34-1, available in two versions: Single-phase, 230 V, with thermostatic contacts in the motor - winding, reconnectible for three speeds, factory-wired for running at high speed. 3-phase, 400 V, 4-pole or 6-pole motor. Both motors have degree of protection IP 54. Suspension rods with mounting brackets, LVDZ-03 Unit heater, LVDV Air discharge device, LVDZ-04-bb

3 Installation package To simplify your choice of control equipment, we have developed installation packages for the most common control options. The A-Box When heating is required, the room thermostat starts the unit heater and opens the liquid valve. When the preset temperature is reached, the liquid valve closes and the fan is switched off. Valve with actuator Junction box Unit heater Room thermostat The B-Box When heating is needed, the liquid valve opens and the automatic fan controller, in response to signals from the temperature sensor, controls the fan to accelerate or decelerate in three fixed steps to maintain the preset temperature. When heating is no longer necessary, the liquid valve cloes and Junction box the fan is switched off. The fan speed can also be manually set at three different speed settings or be switched off. An LED indicates when the valve is open and which functions have been selected. Valve with actuator Automatic fan control, FHC, simple Unit heater Temperature sensor

4 Installation package The C-Box When heating is needed, the liquid valve opens and the automatic fan controller, in response to signals from the temperature sensor, controls the fan to accelerate or decelerate in three fixed steps to maintain the preset temperature. When heating is no longer necessary, the liquid valve closes and the fan is switched off. The preset temperature is shown in the display. The control unit has provision for the following accessories: Alarm indicator for external alarms, time switch for day/night operation, remote control via wire or infrared light and network connection. The software for establishing a connection to a computer is included, LAN, 0-10 V signal (microprocessor substation).
