The fan can be switched on to one of three available speeds manually with the external speed switch S (e.g. P3-1-300) or switched off.

The fan can be switched on to one of three available speeds manually with the external speed switch S (e.g. P3-1-300) with parallel turning on the light in the room or switched off with parallel turning off the light in the room. The fan cannot be switched on without turning on the light and vice versa.

The fan runs permanently at the first speed or second speed. The speed is selected with SW switch.

Connection of basic two-speed fan models with timer (T), regulated timer (TR) or interval switch (I)

Wiring diagram 6

Timer (T) or regulated timer (TR) modification:
The fan with T and TR modification runs permanently at the first speed with the closed SB switch or is switched off as the switch is open. The fan can be switched on to the second speed manually with S1 switch with parallel turning on the light in the room. Turn-on delay time for the second speed then makes 50 seconds for T modification and from 0 to 150 seconds for TR modification. After switching off S1 switch the light in the room is turned off, but the fan keeps running for the time period set by the timer, i.e. 6 minutes for T modification and from 2 up to 30 minutes for TR modification, then it switches automatically to the first speed or switches off.

Interval switch modification (I):
The fan with the interval switch (I) permanently runs at the first speed with the closed SB switch or is switched off as the switch is open. The fan periodically switches to the second speed within the switching interval from 0.5 to 15 hours set manually and continues operating with the second speed within 10 minutes. The fan can be switched on to the second speed manually with S1 switch with parallel turning on the light in the room. Turn-on delay time for the second speed then makes 50 seconds. After switching off S1 switch the light in the room is turned off and the fan resets to the interval operation mode.

The fan is switched off in the starting position. As the light is turned on in the room, the fan switches to the second speed operation by means of the photosensor. Turn-on delay time for the second speed is 50 seconds. After turning off the light, the fan keeps operating within the time period set by the timer from 2 to 30 minutes, then it switches off automatically. The first speed is not used in this diagram.

The fan permanently runs at the first speed with the closed SB switch or is switched off when the switch is open. When the light is turned on in the room, the fan switches to the second speed by means of the photosensor. Turn-on delay time for the second speed is 50 seconds. After turning off the light, the fan keeps running within the time period set by the timer from 2 to 30 minutes, and then switches automatically to the first speed or switches off.

The fan runs at the first speed with the closed switch SB or is switched off when the switch is open. As the relative humidity level in the room increases, the fan switches automatically on to the second speed and run so till the humidity level drops to the required value.

The fan runs constantly at the first speed. As the relative humidity level in the room increases, the fan automatically switches on to the second speed and runs so till the humidity level drops to the required value. Additionally, the fan can be switched on to the second speed or switched off manually with S1 switch parallel with the light in the room. Turn-on delay time for the second speed is 50 seconds.

The fan runs at the first speed if the light in the room is turned on with switch S1 or is switched off if the light is turned off. As the relative humidity level in the room increases, the fan switches automatically to the second speed and runs so till humidity level drops to the required value regardless to S1 position.

The fan is switched off in the starting position . As the relative humidity level in the room increases, the fan switches automatically to the second speed and runs so till the humidity level drops to the required value. Additionally the fan can be switched on to the second speed manually with switch S1 or switched off parallel with the light in the room. Turn-on delay time for the second speed makes 50 seconds. The first speed is not used in this diagram.
