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 122ºF (50ºC).
• If you desire to change the set temperature with dipswitches, please refer to the diagram on
below. These temperatures are available: 104ºF, 113ºF, 122ºF, 131ºF, 140ºF, 158ºF, 176ºF,
and 185ºF.
• 140ºF, 158ºF, 176ºF and 185ºF are for heating applications only.
• 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 99ºF to 176ºF 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-K3/T-K3-Pro in a recirculation system.
This will cause damage to the heater and void the warranty.
