Turn off all electrical service to the unit before accessing the limit or other controls inside the
control cabinet or burner vestibule. Close and fasten the control cabinet and burner vestibule
cover before restoring electrical service. The cabinet and burner vestibule contain High Voltage
wiring and terminals. If the electrical service is not turned off and these terminals are touched,
a dangerous shock causing property damage, personal injury or death could occur.
11.3 Operating Temperature Control
An adjustable digital operating control is located in the front control panel. This control is
continuously updated by the EdgeSC controller so any adjustment will be reset unless there is a
communication error. It is not recommended to adjust the water heater temperature directly onto
the Lync Q water heater unless performing troubleshooting.
11.4 High Water Temperature Limit
The Electronic Operating Control System (EOS) includes a single probe that contains the limit
and operating sensors. Since both sensors are in the same location in the heated storage tank,
the EOS checks to be sure their output is within a degree or two of each other. If not, or if the
maximum water temperature exceeds 200ºF, the EOS will lockout and the manual Reset button
on the control panel must be pressed before the water heater will resume operation.
