Hi im looking to wire a st3pf delay off timer, adjustable up to 3mins to the water pump that feeds the night heater in my camper, basically i want the pump to run on for 3 minutes after i turn the night heater unit off.
The diagram on the side of the 8 pin plug in timer states;
terminals 7 and 2 input; (doesnt state which is positive and negative)
terminal 8 com
terminal 6 no
terminal 5 nc
above terminal 3 is the word "connection" then a linking line to the word "reset" before carrying on to link to terminal 4
terminal 1 has been ommitted.
can someone explain which wires i need to link to which terminals?
thanks
stevie

Hi thanks for that, i assume 120v will work in much the same way as a 12v timer, although im still not sure which wires i should be attaching to terminal 3 and terminal 4

I believe 3 and 4 you hook up a momentary switch to reset the device.
With the model# you provided, that is the diagram.
