Okay, that solves the confusion. :) For your requirements I would adapt a standard furnace programmable thermostat and use that to drive a regular or solid-state relay to control the heater. You would need to get a small 24VAC transformer to power the thermostat and relay. This has some information about how the thermostat is connected. If you need clarification on the connections, just post your questions.

Hello,

Here is a simple thermostat that uses a relays to switch the heater:



You can double the potentiometer and switch between day ans night temperatures.
