I am planning on building a herms system. Wanted some input on my controls:
RANCO ETC 24V
specifications listed here: http://www.etcsupply.com/ranco-etc11...24v-p-102.html
Honeywell VR8300A Continuous Pilot Combination Gas Control
Voltage and Frequency: 24 Vac, 50/60 Hz.
Current Draw: 0.70A.
Honeywell 36 in. Lead Length Universal Gas Thermocouple
purchased at home depot
Honeywell Q314A4586 - Pilot Burner for Natural or LP Gas
Do I need any other supplies to get a simple HERMS built? For the electricians out there, do the supplies I listed above work together electrically?
This is my understanding of a HERMS system from my reading, please let me know if I am way off:
So I lite the pilot, then I will set the RANCO to a certain temperature. The Ranco temp probe will be in my HLT. When the temperature in the HLT drops below the set temperature, the Ranco will send a signal to the gas control valve, opening the valve. The pilot light ignites the gas and the butner is lit. Once the water in the HLT heats back up to the preset temperature, the Ranco sends a signal to close the valve, the burner is extinguished but the pilot is still lit. This happens throughout the mash as a march pump recirculates the wort through a copper coil submerged in the HLT.
Any ideas are appreciated
