What do you like and would like in a timer ?

This is a picture of the unit i will be using. :cool:
Was going to put it on my last message but forgot:stoned:

Any how despite the lack of input to my question I have started working on the controler/timer..

got 2 cycles for the light 12/12 and 18/06

Pump timer on and off

Air fan timer on and off for breif monents while the light is on for CO2 refreshemnt and for when temp goes to hi and shuts off when temp is normal

Is there anything im missing here

Thanks in advance:stoned:
