ELECTRONICS OPERATION ALGORITHM

The fan with the T timer activates upon control voltage application to input LT (ST, SL) by an external switch (e.g. indoor light switch). After the control voltage is off, the fan continues to operate within the set time period adjustable from 2 to 30 minutes by the timer.

The fan with the T1 timer - when the control voltage is applied to the LT terminal by an external switch (for example, switching on the room light), the turn-on delay timer is activated, and the fan does not start. After the turn-on delay time runs out, the fan starts to run.

Turn-on delay time value Tz is adjustable in two ranges from 10 seconds to 90 seconds and from 2 minutes to 30 minutes. Select the adjustment range using the jumper on the timer board. After the control voltage is off, the fan continues to operate within the set time period adjustable from 2 to 30 minutes by the timer.

The fan with the timer and the humidity sensor TH - the fan starts after the control voltage is supplied to the input LT (ST, SL) or if indoor humidity level H exceeds the set point adjustable from ~60 % to ~90 %. After the control voltage is off or the humidity level has decreased, the fan will keep running within the time set by the timer ranging from 2 to 30 minutes.

| THE TIMER CIRCUIT IS LIVE. MAKE SURE THE FAN IS DISCONNECTED FROM POWER SUPPLY.
---|---

The fan with the timer and the TR motion sensor - the fan starts when a person moves at a distance of 1 to 4 meters with a horizontal viewing angle of the sensor of 100°. After the movement stops, the fan continues to operate within the set time period adjustable from 2 to 30 minutes by the timer.

WARNING! The fans rated for 12 V power voltage (stated on the packing box and on the fan casing) connect to 12 V power mains only!

| DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD.
