Pool Hawk worked great for 4 weeks or so but suddenly today started showing 33 degrees in 65+ degree water. Have followed the recommended steps below to the letter with no change.

Hard reset:
- Bring both units side by side and remove all batteries, unplug display if it has an ac adapter
- Change the ABC Switch to a different setting and ensure that both are on the same setting. example - If on A, move both to C
- Place batteries into the outdoor sensor first 
- Place batteries into display
- Allow units to sit side by side until they connect

Hello Michael,

Please verify are using the battery recommendations listed below. Thank you.

Batteries:

•Verify you are using fresh alkaline batteries or lithium batteries (when temperature is below -4oF/-20oC) in sensor.

•Quality brand batteries are recommended, including Duracell, Rayovac, Energizer, or Kirkland.

•Verify batteries are fresh. The battery expiration date should be at least 6 years out. Batteries can lose 3% power or more every year in storage.

•Heavy duty, extra strength or generic / store brand batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the way these types of batteries disperse power. Each battery should not exceed 1.6 volts.

•Rechargeable batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the voltage instability of these types of batteries.

•Mixing different battery types (brands, old/new, etc.) is not recommended.

Thanks for the follow-up. The batteries are brand name. I took them out of the transmitter overnight and put it back together this AM. The temperature now is showing correctly. I had similar behavior yesterday after removing the batteries for 30 min., but the temperature went back to ~20 degrees (from mid 60s) after a couple of hours. I will continue to monitor.
