Re: [RE-wrenches] 48 V DC temp sensing relay
White-Rodgers-1609-101-Refrigeration-Temperature-Control- I have used this many times in various applications some close on temp rise other model closes on temp drop. Quite reliable! ___ Dana Orzel c- 2087217003 e - d...@solarwork.com --- Begin Message --- Hi Drake Try this one. I get a lot of equipment from supply house. Since you need on with temp rise it’s an AC type. This one will do 8 amps at 120v so a small amp dc fan won’t hurt the relay.

Have you considered using a thermostat? Like the A19 series. Mechanical, non-electric.
