Hi Everyone, I recently got my Ranco backup all in place. I have a Helix DBS 1000 controlling my racks and a Ranco ON/OFF placed in front of it in the circuit as a backup. I have the probes for the two thermostats placed in almost identical spots on the Flexxwatt and the Ranco reads 4 degrees cooler than the Helix?! Anyone experienced anything similar?
