[Hai-users] Lifespan of RC-80s and monitoring service question

[Tom Morgan]

One thing to note about RC80's, electrically speaking, it is 'a sitting
duck.'  It sits between the HVAC transformer and the HAI transformer and
there is tons of wire.  I have 2 strong recommendations:
- Install whole house surge (Like the Leviton 51110-1 $45.33)
- Review your grounding.  The HAI controller MUST be grounded. When not
properly grounded it is not uncommon to have thermostats fail.

Before I followed the advice above I lost 2 thermostats at my home and 2 at
my parents.  After making the above changes we have not lost a thermostat in
over 5 years.

Why are you losing the RC-80's what is happening?  Maybe you need an
isolation relay (HAI product) if it is being fried somehow.  Give me some
more details I might be able to offer you some assistance in
troubleshooting.  I helped figure out a problem with 128 RC-80 thermostats
in an apartment complex, your situation should be simpler to figure out.
