A TMC Trigger Delay can be adjusted to help eliminate false alarms (see “TMC Trigger Delay” on page 45 ).
WARNING
SCALD HAZARD! Water temperatures over 125°F (52°C) can instantly cause severe burns. Children, disabled,
and the elderly are at highest risk of being scalded. If anyone using hot water in the building fits the above
description, or if local codes or state laws require specific water temperatures at the outlet, it is
recommended to not exceed at Setpoint limit of 125°F (52°C). Water drained from system drain valves may
also be extremely hot. Make sure all connections are tight and direct all water flow away from personnel.

Description:
The TMC Trigger Delay prevents the alarm from being triggered immediately and the TMC valve from
closing unless the alarm situation is maintained for the full delay period. This helps eliminate false alarm
situations that normally may only last for a few seconds.

Description:
The TMC Setpoint is the mixed valve outlet temperature above which the ETV Platinum Plus will close the
TMC valve and trigger an alarm. This action prevents the mixed outlet from reaching excessive
temperatures. An alarm message is displayed (see “Alarm Messages” on page
35 ) and the event will be recorded in the Alarm Log (see “Alarm Log” on page 50 ).
