The comment about the BCS having only 4 temps is the BCS-460 model. The BCS-462 has 8 temp probes.

You need to research your options and not rely on threads like this to dictate your decision.

For you guys saying that the BCS requires a computer to run.... technically it doesn't. The computer (or iPad, iphone, etc) are just display devices - there is no logic executing on the computer. The BCS can run stand-alone and all processes can be start/stopped via switches. Most people don't use it this way because they want a full screen display to see everything happening at once.

The BCS does PWM, Hysteresis and PID temp control. It does temperature averaging across multiple sensors. Your processes run independently so like I pointed out before, I can have my kegerator, fermenter, smoker and brew rig all running at the same time. I often do double brew days and the BCS is handling different settings for batch 2 in the MLT while still finishing batch 1 in the BK. The process flexibility lets the system easily multitask whatever processes you want to do.

Many BCS users build full control panels that look similar to many of those shown for the BT systems so that they can do automatic and manual control. Myself, I just use the GUI (on a touch screen brewery interface) and yes, I pretty much run my brew day with the push of a button.

This pissing match about the two systems is stupid. Calling one system vastly superior to another is flat out wrong. Both systems are very capable and each has it's strengths and weaknesses.

I use the spark ignition pilot modules and did have some issues initially with noise affecting the BT. This was resolved by containing all of the Honeywell controller components in a separate enclosure from the BT and other components, using shielded cable for the 24v supply from the BT to the control modules with ferrite cores, routing the cables away from the rest of the cables, and upgrading my temperature sensors to the one-wire sensors with filtering circuit sold by OSCSYS.

I completely agree, but it is nice to hear real world experiences before I invest in a product. I will always do more homework than necessary.

Thank you, it is good to hear a success story. I already have my gas valves for the HLT and the MLT.

If your valves will support HSI's, I highly suggest you look at those instead of the spark igniters. It's a pain to isolate the spark igniters so that you don't have issues with them. I've used spark igniters for the last year, but every once in a while I'd have an issue with them zapping my controller. HSI's have no interference issues at all.

HSI is nice since you are not lighting a standing pilot. Will the BCS allow you to reset the lock out for failed ignition? Most of the Honeywell smart valve can utilize HSI if the ignition box has the ablity to send the right voltage to it.

I don't know. What's required to reset the lock out? If the smart valve (or controller module) puts out a signal to say it went to locked out status, then I don't see why the BCS couldn't react to that and trigger the module back to reset the lockout. I thought those smart valves had that built in to reset & retry when a failed ignition attempt occured... no?

Most times they try to light the 3 times then go into the lockout mode.

Honeywell SmatValves do not have an "ignition box" (ignition module) the ignition sequence is controlled by the valve with no additional control hence the name SmartValve. All the valve needs to operate is 24vac and the ignition sequence is initiated.

SmartValves are designed for many applications and have various ignition sequences and pilot assemblies. The SmartValve I use has an ignition sequence that will continue to repeat until it senses flame so lockout is impossible. Some other SmartValves have a sequence that only attempts to ignite a certain number of times before lockout. Lockout is just another form of safety and can be reset simply by removing 24vac from the valve and re applying it with a switch or relay.

The SmartValve I selected uses the IHSI pilot burner that is made up of the hot surface igniter, flame sensor and pilot.
The sequence is as follows - 24vac applied to valve, HSI is activated, pilot valve open, pilot ignites, flame sensor senses pilot and main burner valve opens. At any point the flame sensor quits sensing flame the pilot and main burner valve will close and restart the ignition sequence. I selected this valve for the simplicity, reliability and redundancy.
