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. TM-RE30).
•
With this optional TM-RE30 you can set the temperature from 100ºF to 185ºF with various
increments.
•
Please read the instructions carefully prior to installing the TM-RE30, 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 185 ºF if you use your T-M50 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.
