Question about Hardware & Accessories
I've wired it with Hot (black) wire coming in and the Black wire from fan and ground wire to switch, I also reversed the Black wires and got the same results. Thanks inadvance for your help...
The manual states that on-and-off blinking of load indicates the load is less than minimum.
Minimum load draw is .3 amps and 40 watts.
Generally a bath fan is 1/6 Hp or 3 amps... exceeding the minimum.
Manual indicates that wiring error can also cause on-off blinking.
MA T530 replace single pole switch,,, and either wire from switch can connect to either brass screw on timer.
This timer will not replace 3-way switch.
Defective product is also possible/ call Lutron 800-523-9466 day or night

the extra white wire from timer goes to the group of white wire ganged together in rear of box. you need to connect a jump wire to tha group and lead to timer. grey wire goes to black. red to red.

HI .. if the switch has only a black and white wire attached, and there are no other wires in the wall box, then you cannot use this timer switch. You need to return it and get a timer that does not use a neutral connection. The wires you have are a switch leg from the light and there is a white wire but it is not a neutral.
If there are other wires in that wall box , tell me and we can chat more about how to remedy this .

The usual connection for this type timer is the house black power to the timer black, the house white power to the timer white and the , the light black wire to the red timer wire.
If you only have two wires, one black and one white, at the switch location, then you cannot use this style timer , as it needs a neutral. You should return this timer and get one that does not require a neutral connection.

What you have a single pole light switch you are replacing with the timer. As you say you have 2 black wires. One black wire is the incoming power wire and the other black wire goes up to the light. On a normal single pole switch is makes no difference which of the screws you connect it to. Of course with the exception of the ground screw. Tie all the white wires back together that are in the wall box and shove them to the rear as they are not needed to make this connection. The correct connection is to connect one of the black existing black wires in the wall switch box to the black wire on the timer. Now connect the other black wire to the blue wire on the timer. The red wire is not used in a single pole connection and is only used in a 3 way switch connection, so just put a twist connector on it and shove it back in the box. To recap, connect black wire on timer to either black wire in box. Connect the other blue wire to the other black wire. Do not use the red wire. Hopefully you did not hurt the timer by connecting it incorrectly. If it does not work after setting the timer up according to the instructions you have ruined the timer by wiring it incorrectly. Hopefully no damage has been done.

Switch has 2 black wires. One black is hot wire. One black is wire going to fan. Turn off power. Remove wires from switch and separate. Turn power back on. Using ordinary tester, test each black wire to bare copper ground wire. Only one of the black wires will test hot. The other black wire goes to fan.
Timer black wire connects to black hot
Timer blue wire connects to black wire going to fan
Timer white wire connects to white neutral (in absence of white neutral, connect Timer white wire to bare ground)
Timer green connects to bare ground wire
