Video: Mash Heat via HERMS coil
25 Jun, 2014
This shows the Brewtroller keeping the mash at the target temperature by switching between just recirculating it and reciruclating it via the HERMS coil. I set the HLT target to be 40.0C and the mash target to be 32.0C.
It seems to be pretty accurate at holding the mash temperature, but I think the HLT temperature probe will need to be moved to get a more accurate reading of the HLT temperature and avoid overshoots.
