• If you desire a hot water temperature other than the 8
preset settings, please purchase the optional tempera-
ture remote controller (part No. TM-RE30).
• With this optional remote controller you can set the tem-
perature from 38°C to 85°C (100ºF to 185ºF) with various
increments.
• Please read the instructions carefully prior to installing
the remote controller, as failure to do so could damage
the temperature controller and/or the water heater, which
will void the warranty.
Turn off the power supply to the heater
before changing the DIPswitch settings.
Only change the switches with the dark
squares. The dark squares indicate
which direction the DIPswitch should be
set to.
DO NOT set to 85°C (185°F) if you
use your water heater in a recirculation
system. This will cause damage to the
heater and void the warranty. •
