You could leave the circ. pump on constantly and step temperatures with the HLT or you could set the HLT to one temp, say 160F and use the pump for control of the temperature in the MLT. One is not better than the other in my opinion. Either way you have a completely automated mash. S.
So...tell me if this sounds like the right idea:
4 Temperature Probes:
1) Boil Kettle
2) Mash Tun
3) Hot Liquor Tun
4) Probe for Wort flowing out of HLT and back into MLT
1) Pilot Light
2) Scolenoid Valve on HLT
This would allow me to monitor the temperature on all my vessels and control the burner for the HLT. Thus, if I wanted to a step mash, I would always have the pump flowing, but I'd control the heat of the water in the HLT with the Scolenoid valve. Pilot light would essentially stay on during the entire mash....if so, would that even need an output?
Questions: How much is a float switch and a switch for the pumps to control an automated fly sparge?
Right now I'm thinking this rig would cost me to batch sparge:
$200 Box of Miracles
$64 for Probes from ECC website
$10 for 1 relay for Scolenoid Valve
$120 Scolenoid Valve
$100 Immersion Chiller for HLT Coil
$50 Fittings for Chiller in HLT
$70 Tubing & Disconnects
Total - $764
What am I missing/miscalculating?
