=== Tunable parameters ===

Besides choosing which gases to add to the HFR, there are a few tunable parameters:
* '''Heat conductor'''. Sets the maximum internal rate of change in the Fusion Mix's temperature, in either direction (though the Endothermic cap is one tenth the size). Along with the Fuel injection rate, one of the two values that will see the most tuning:
** Maximize when attempting to increase fusion power levels.
** Minimize if you need to leave the HFR unattended for a minute.
** Set to the highest rate your cooling setup can stably handle when attempting to maximize production.
** Maximize when attempting to reduce fusion power levels, if you successfully flipped the reaction to be Endothermic (cooling).
** Minimize when attempting to reduce fusion power levels, if you could not flip the reaction to be Endothermic.
* '''Magnetic constrictor'''. Should almost always be minimized, at 50. If your mix has an extremely large volume, constricting it to the smallest space can destabilize the reaction, flipping it to become endothermic. When this isn't a concern, higher values reduce the magnitude of the reaction and the scale of gas effects, which can be situationally useful if you need to leave the HFR unattended for a minute. The Heat conductor is generally a more effective means of control. Maximize when attempting to reduce power levels, if you could not flip the reaction to be Endothermic.
* '''Fuel injection rate'''. This serves two purposes: It sets the rate at which gas is pulled from the fuel port into the Fusion Mix, and it also sets the scale at which gas is consumed - one of two key factors for how much gas is produced. There is no way to separate these two purposes. The HFR will always try to pull more gas in than it consumes, so be sure to have a gas pump or gas mixer keep fuel input at low pressures in order to avoid overfeeding. Along with the Heat conductor, this is the value that will see the most tuning:
** When initially fueling the HFR, this should have a high value, to bring the Fusion Mix up to a functional volume quickly. 250 to 500 is fine. You could also have this maxed out if you want to exclusively manage the external fuel input rate with a gas pump or gas mixer, although this risks consuming gas at a far higher rate than necessary.
** During stable production, this should have a value paired with the heat conductor value to optimize the production rate while avoiding gas waste. See the table in "Key Parameters" below for details.
** When trying to process output gas, this should be set to the minimum value, at 5, while Waste Remove is also set to Off. This mostly minimizes (hot) gases being added to the output port, without wasting fuel, giving any freezers or space cooling time to cool existing output that was already removed. The reaction can be flipped Endothermic to completely stop output gases from being added, but this will burn fuel for no production, and setting the FIR to 5 is almost always sufficient.
** While trying to return to a safe temperature, without attempting to starve the Fusion Mix, this should be set to the minimum value, at 5. Gas is not produced while the reaction is Endothermic, so there shouldn't be a need to burn more fuel than necessary.
** While trying to return to a safe temperature, with attempting to starve the Fusion Mix, this should be set to the maximum value, at 1500, in order to burn away the Fusion Mix as quickly as possible. Note that this can also burn through any reserve of Healium extremely quickly!
* '''Moderator injection rate'''. Sets the rate at which gas is pulled from the moderator port into the Moderator Mix. If the moderator port is directly linked to a connector, and supplied with canisters, it's generally safe to leave this maxed out at 1500. Leaving it maxed out also means one less setting to change when you want to rapidly add room-temperature gas to the Moderator Mix to cool it down, and every second often counts.
* '''Current dampener'''. Increases the instability of the reaction. A sufficiently unstable reaction will flip the reaction from being Exothermic (heating) to Endothermic (cooling), albeit with a negative heat change cap one tenth of the magnitude of the positive heat change cap. A mix increasing at 5x10^6K will decrease at 5x10^5K instead! This works even at unsafe fusion power levels, and is the main way of correcting reactions about to get out of hand. Given that this flip is all-or-nothing, this should be set to 0W (nothing) or 1000W (maximum) at all times.
* '''Waste removal'''. If enabled, 50% of each of the Byproducts created by the selected recipe per second, 5% of the Fusion Mix's Anti-Noblium per second, and any user-provided Moderator filter gas are moved from their mix to the output. Forcibly disabled at fusion power level 6. Note that any gases created by the reaction directly in the output bypass this - see the table describing moderator gas effects in "The Moderator Mix" below.
* '''Moderator filter'''. If Waste removal is enabled, this removes up to 20 moles per second of a gas of your choice from the moderator mix, placing it into output.
