Instruction for changing the setting back to 120ºF (49ºC):
WARNING: Improper adjustment, alternation, service or maintenance can cause property
damage, personal injury, or death.
Adjustment to LIMIT maximum water temperature setting to 120ºF (49ºC) by the Main
Remote Control (UMC-117)
WARNING: Changing this setting is done at your risk.
WARNING: Water Temperature over 125ºF (52ºC) can cause severe burns instantly or death from scalds.
Children, disabled and elderly persons are at highest risk of being scalded. See the Instruction Manual before
setting the temperature on the remote control. FEEL WATER BEFORE BATHING or SHOWERING. DO NOT
leave a child in the bath unsupervised.
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 120ºF (49ºC).
Note: We recommend that you install the thermostatically controlled tub and shower valve & tempering valve
for your safety.
Follow the instruction below if it is determined that a setting of up to 140º (60ºC) or 185ºF (85ºC) is no longer
required.
(1) Turn on the remote control (UMC-117). Turn off the gas and water shutoff valves.
(2) Press the DOWN arrow temperature adjustment button on the remote control for several times and set the mini-
mum setting temperature at 100ºF (38ºC) or 85ºF (29ºC).
(3) Press and hold the DOWN button on remote control for more than 5 seconds. Number on the display of the remote
control will begin to blink.
(4) While the number is blinking, push the DOWN arrow temperature adjustment button and the UP arrow temperature
adjustment button at the same time. Number on the display of the remote control will stop blinking.
(5) Push the UP or DOWN button to set desired temperature.
(6) Turn on the gas and water shutoff valves.
(7) Check and ensure safe operation and performance of the water heater.
