Thermostat opens at 130*F --- closes at 100*F for reheat cycle
Water temp has to be at 100*F or lower
Can check continuity thru a cold t-stat
HI temp T-stat opens at 170*F and has to be manually reset (Push to Reset cover above gas valve----right side is the 12VDC for gas)
Hi Temp T-stat is always closed unless it trips
Circuit board gets 12VDC after it has gone thru the set of t-stats
Course that is IF you have 12VDC to/thru the on/off switch and thru the DC Junction Box
