Sorry I missed your post
Could I ask you to elaberate here, I am struggling slightly with the math, The pin for 6 seconds Given R8 and C2 Would be pin ? I have it at 7?Here's a repeating timer using a cd4060 R8, C2 set the on time (6seconds) the long time period is set using the desired output pin, R3,R4, C3.
Without access to Q11 (internal on the CD4060), the math gets sticky going for a 3600x turn-up factor (6 seconds ON and 21600 seconds OFF). How would you set the math to get both a 6 second and 21600 second duration off of one chip? It seems much easier with two chips.Why are you using two chips, when one will do?

This is the essence of DD's idea in post #5 - Set the oscillator to a 12 second period (6 seconds up to form the output pulse, and 6 seconds down), and decode a count of 1800 for the reset signal. For good-enough timing with less logic, decoding 1728 takes only two outputs, and reduces the cycle time to 5.76 minutes. If you adjust the oscillator for a 12.5 second period, 1728 decodes exactly 6 hours.Without access to Q11 (internal on the CD4060), the math gets sticky going for a 3600x turn-up factor (6 seconds ON and 21600 seconds OFF).
