[Hai-users] tstat power reset

[Dudoussat, Scott A.]

Do you have a common wire from the HVAC transformer connected to the "C" terminal of the RC-80?  If not, you may need to connect one.  If the wire isn't there and it's not feasible to run one, you can connect the HAI 30A00-2 Thermostat Power Supply Module to the HVAC system to remedy the issue.

Subject: [Hai-users] tstat power reset

I have a RC80 tstat that appears to randomly go through what looks like a power reset (the display "blanks" out followed by every line of text displayed on the LCD).  By random, it may occur several times a day or once a week.

this tstat has been installed going on 12 years and has never given me a problem before.  Wiring to both the panel and the HVAC equipment are fine.

tstat going bad?

thanks
