How do I wire a Honeywell RTH8500D so that it does not need the battery as the primary power source? I have a two wire 24vdc hot water system that connects to a Taco SR502 switching relay.... Forum: diplofix.com - From: Rudy - Date: 2008-11-01 16:38:16
MY RTH8500D is going through a set of batteries every 3 to 4 months. conventional gas forced air furnace with a/c.
Is anyone else having this problem?... Forum: diplofix.com - From: RichM - Date: 2008-11-16 20:01:12
