The dark squares indicate the direction
the dipswitches should be set to.
TEMPERATURE SETTINGS
There are 8 preset temperatures that you can select from by changing the dipswitch settings
on the computer board.
The temperature has been preset at the factory to 120ºF (49ºC).
If you desire to change the set temperature with dipswitches, please refer to the diagram on
below. These temperatures are available: 100ºF, 115ºF, 120ºF, 135ºF, 145ºF, 155ºF, 165ºF,
and 185ºF.
If you desire a hot water temperature other than the 8 preset settings, please purchase the
optional temperature remote controller (part No. 9007603005 (TM-RE30)).
With this optional remote controller you can set the temperature from 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 185ºF if you use your water heater in a recirculation system.
This will cause damage to the heater and void the warranty.
To change dipswitch settings
for temperatures, locate the
lower bank of dipswitches to
the right of 7-Seg LED.
DO NOT adjust the upper bank
of dipswitches.
