Temperature Probe Port
This temperature probe ensures that
a safe minimum temperature threshold
is maintained to prevent Legionella
bacteria’s development.
Water Detection Cable Port
The optional water detection cable
detects potential leaks, sends an alert
on your mobile device, and can turn off
the water heater power when a leak is
detected by using an automation.
Note: If your water heater has been turned off
for several days, it is recommended to wait until
the water temperature has reached 60 °C (140 °F)
for 4 hours and then let the hot water run for a
few minutes before using it.
Insert the water heater wire (load) and the power
wire (line) into the electrical box and secure them
with wire clamps.
Install an electrical box ground wire to the water
heater ground screw.
