timer-based operating logic ( LM U1): I +
This logic is used for exact air temperature control. The motor changes its speed more often as
compared to the temperature pattern, but one speed interval continues at least 5 minutes.
The motor sets to maximum speed as the temperature reaches the thermostat set point.
If the temperature drops below the set thermostat point, the motor sets to set by the speed controller
speed 5 min. after the timer countdown. If the initial temperature is less, the motor starts operating
at set speed immediately.
The fan LM P (fig. 3 ) is equipped with a speed controller that enables switching the fan on/off,

smooth speed (air flow) regulation from minimum to maximum value.
MOUNTING
The fan is suitable both for horizontal or vertical mounting on the floor, on the wall or on the ceiling
(fig. 2) as one unit or included into connected in parallel.
In case of the horizontal fan mounting install a straight air ducts segment on side of the intake vent
not less than 1 m; in case of the vertical fan mounting install an outer hood to prevent water ingress
inside the fan. The exhaust pipe must be connected to the air duct.
The mounting sequence is shown in fig. –1 and 2 –
