Love the mod! It would be really awesome if we could both read the temp on this with the circuit network, and set the power level too (not just on/off, but how many MW).

It's my first one, but I'll try to add these functions

Would be great! So far I'm putting heating tower near it and its heating up slowly from electric one - then I can get temperature.
Really not make sense to not have primitive electric heating technology while on other planet xd

+1 for this. Love the idea, but constant running at 400C is overkill and a huge power drain.

Circuit connection would be nice, but can be complicated, since you need a hidden combinator, from what I've seen. However, Z4NON, you can just set scale_energy_usage = true in the reactor entity prototype, and it'll automatically shut itself off once it hits maximum temperature, at least avoiding the continuous 40 MW consumption when it's not actively heating that much.

scale_energy_usage    optional    :: bool
When this is true, the reactor will stop consuming fuel/energy when the temperature has reached the maximum.

I've thrown it in the prototype locally, and it does in fact meter the electricity input to match the actual heating needed, once it hits its 400 C limit.
