Time/Temperature Relationship in Scalds
Follow the instruction below if it is determined that a setting of up to
140°F (60°C) or 180ºF (82ºC) is no longer required.
(1) Turn off remote controls. Turn off the gas and water shutoff valves.
(2) Remove the front cover.
(3) Find the DIP Switch #4 located at the top left hand side of the PCB.
(See illustration to the right for DIP Switch location)
Location of DIP Switch on PC Board.
(4) Change the DIP Switch #4 setting to the “ON” position. DO NOT
alter any other DIP Switch. (The LED on the PCB is on. At the same
time, the display of the Main Remote Control is on continuously.)
(5) Press the “Min.” Button on the left hand side of the PCB for more
than 1 second. (The LED on the PCB starts flashing. At the same
time, the display of the Main Remote Control starts to flash.)
(6) Change the DIP Switch #4 setting back to the “OFF” position. DO
NOT alter any other DIP Switch. (The LED on the PCB will stop
flashing. At the same time, the display of the Main Remote Control
will turn off.)
(7) Attach the unit’s front cover.
(8) Turn on the remote controls, gas and water shutoff valves.
(9) Check and ensure safe operation and performance of the water heater.

Danger: Hotter water increases the potential
for Hot Water SCALDS.
Notice: For safety reasons the BATH Remote
Control(s) cannot be adjusted to temperature
above 120°F (49°C).
WARNING: DO NOT alter any other DIP
Switch.
WARNING: Water temperature over 125°F (52°C) can cause severe burns
instantly or death from scalds. Children, disabled and elderly are at highest
risk of being scalded. See the Instruction Manual before setting the tempera-
ture on the remote control. FEEL WATER BEFORE BATHING OR SHOWER-
ING.
DO NOT leave a child in the bath unsupervised.
WARNING: Change the setting to 140°F
(60°C) or 180ºF (82ºC) is done at your own
risk.
Note: The maximum water temperature is set
at 100°F (38°C) from the factory.
Note: We recommend that you install the
thermostatically controlled tub and shower
valve & tempering valve for your safety.
Temperature Time to Produce Serious Burn Temperature Time to Produce Serious Burn
120°F (49°C) More than 5 minutes 140°F (60°C) Less than 5 seconds
125°F (52°C) 1-1/2 to 2 minutes 145°F (63°C) Less than 3 seconds
130°F (54°C) About 30 seconds 150°F (66°C) About 1-1/2 seconds
135°F (57°C) About 10 seconds 155°F (68°C) About 1 second
