The Control Module provides the temperature reading and control functionality that sets this product apart from the rest. Never before has this level of sophistication been available to home brewers in such a sleek, compact, and easy to use device. All you need to do is choose your target temperature (mash tun or hot liquor tank) and the Control Module will do the rest by automatically turning on/off your burners (natural gas or propane) till the desired temperature is reached. Accurate and precise temperature control held to 0.5° F (0.25° C). Set it and forget it (we actually don't really mean that; you should definitely still pay attention but it just sounded fitting in this context!). Buy another one and control both your mash tun AND your hot liquor tank. Each Temperature Control Module comes with the following:

• Ultra high precision and accuracy PID controller and Class A precision RTD temp sensor. Sensor can be installed in any 1/2" hole in your pot for a HLT or into any 1/2" NPT fitting with the included adapter bushing.
• A pilotless electronic ignition control system that adapts to ANY burner (natural gas or propane); not just a Blichmann burner! This ignitor will instantly relight your burner if blown out by a wind, and will shut down your gas if a flame is not detected within 10 sec and will sound an alarm. Includes industrial ignition electrode and high quality silicone/carbon fiber ignition wire.
• US made gas solenoid valve (installs on your burner gas supply)
• Data port for optional remote monitoring and mash profile programming (unlimited profiles) on your PC (optional Communications Cable required)
• Convenient cable storage tray in the back of the enclosure to neatly store wires between uses.
• Includes a decal for MASH and one for HLT so you can label appropriately.
• Compact enclosure is 4.25"W, 7"H, 7"D - easy to integrate into your brew system
• Brushed stainless cover and gloss black powder coated case will look beautiful for years
