Logic Thermostat 20-25C
By Gears
A simple easy setup for controlling temperature in your base using wall coolers/heaters.
Wiring diagram

Alright so here is a simple thermostat design.
Heat kicks in from 0 to 20C then at 20C it cuts off.
Cooling kicks in from 25 on.
The circuit used wall heaters and coolers that are on the same circuit, I would recommend to put the heating/cooling system on it's own apc so as to make sure it's only turning on the ones you want to be on.

If you havent labled anything, this is the time to start, lableling the compare and memory unit

Bill of materials minus wiring..haha.
2 Logic Processors used at compare units (middle mouse scroll)
2 Logic Memories
3 Logic I/O
1 Gas sensor

If there are any questions feel free to hit me up.

Thanks for the inspiration. I used this idea to do something similar for pressure, turning two volume pumps on when the pressure was in the sweet spot (105-120 kPa)-- and turning off the intake or output pumps when pressure gets out of whack. (Mem-105, Mem-120, Reader-Gas Sensor-Pressure, Compare Pressure<Mem-120, Compare Pressure>Mem-105, Write(single)-Volume-Pump (when Pressure>=120, to disable the pump that moves air from storage/filtration into the room) and Write(single)-Volume-Pump (when Pressure<=105, to disable the pump that moves air from the room into filtration/storage.) -- this creates a always-on filtration process that self-balances room pressure.

Well they turn off automatically once the temp reaches that lower threshold. Sounds like they're doing their job, but the heat sources are keeping it at the upper limit. Possible ways to rememdy it are to turn up the temp it activates on, remove some windows to limit greenhouse effect or put the coolers in their own room with pasive vents between that n rest of your base. That would isolate the noise some.

The wall heaters do their job fine. I've got a few things in the room i've got it setup in which are causing heat to rise, I think crafting stations, lights, and other electronic equiptment naturally generate a little bit of heat. I tried looking around to see if there's some way to turn the coolers off via logic but it doesn't seem that exists yet.

Kohveras, question. Do the wall heaters kick on at below 20C? If the system is working properly it can still stutter the coolers on and off as it's at that temperature threshold for the sensor, or if you've got a heat source somewhere which I am thinking may be the case, they turn on once the sensor passes that 25C threshold, and then back off once it's met. Some bases I've done find a settle point temp wise, the one I am currently on is around 23C, minus the furnace room which if I didnt cool would probably get extremely high. The temp ranges are adjustable via the logic memory set-up on the circuit. You could raise your value for the cooling logic memory circuit to 303.1 which is kelvin, which would be around 30c. See then if your base finds a natural happy place temp wise, sometimes they dont and the rudimentery circuit continues to cycle on and off to regulate temps.

So i've done this but all that happens is the wall coolers click on and off constantly trying to keep the room at 25 C. is there a way to stop that from happening?

You are correct, my appologies for this, I had turned them off to stop my heat/cool cycle while I had pulled vacuum on my base. Thanks

This guide is extremely helpful. The picture is flawed though. The batch writers need to be on in order to be used. I had them off the entire time and wondered why it was not working. Thanks anyways!

Also before I just had ran 1 logic memory, so the second the heaters kick off, coolers clicked on, so they basically would fight themselves for that 20C spot, it got obnoxious after a while, thus the 5C range, realistically it could be pulled further apart temp range wise anyway.

Yeah it does, but i don't mind as long as it keeps my base from going boom, lol. I havent any real timer functions in any of the logic i've played with, but it'd be nice that once it brought it down to a temp it could kick a timer of say 20-60 seconds so long as it didnt pass a threshold of say 30c. In my experience heat ups come bast, and it's nice to have a cooling system to handle it without too much worry. Maybe up your cooler turn on kelvin in memory some n see if your base will establish a range on its own maybe...

It's a good setup. I did mine on my own the fly. Yours looks cleaner. I just thought it was cool how we came to the same setup. Does yours sometimes tick-tock the cooler at night? Drives me mad. I thought about coding a more complex variance just to get it to settle. lol
