I have a salt water aquarium where the water temperature can get too warm.
I've installed a CPU cooling fan on the hood and find it is very effective in bringing down the temperature. I'd like to put this on a thermostat.
I’ve disassembled a working aquarium heater and plan on wiring it to the fan. Here is the problem: The heater logic is opposite of what I need.
When the water is too cold, the heater comes on. When the water is warmed to the setting, it turns off.
This sounds like a job for a RELAY… one that is open when current is applied and closed when current is removed. Also, it needs to be an AC relay.
I’ve been looking on line and have found dozens.
I’d be interested in hearing suggestions on the relays for this application.
Thank you in advance.
