I'm trying to find a timer to do what I want. Descriptions on the

I want a timer that if it has input, say from a thermostat, to come on
for a set time (2 to 5 minutes) and cut off. And I want it to do this
every 15 minutes to 2 hours. What kind of timer do I need.
I don't mind wiring an octal socket it they come that way.
