This issue may occur during a
power outage or power fluctuation
in the system.
If persistent or if it coincides with
the system operations then pro­
ceed with the following trou­
bleshooting steps.
> Check the power connec­
tions
> Check the amp draw at the
transformer (the transformer
maybe overloaded)
> Check 24VAC voltage at the
system component (device).
If the fault persists after checking
the connections, replace the unit's
control board.
The applicable system compo­
nent is missing the programmed
