Description:
The Setpoint is the mixed valve outlet temperature the ETV will hold during normal operation. The
temperature may fluctuate slightly around the Setpoint. The amount of fluctuation is controlled by
the Gain setting (see “Modulating Gain” on page 46 .)
If the Setpoint Input was set to EMS 4-20mA, the setpoint will be available as read-only and can
only be changed remotely using the 4-20mA input signal (see “Setpoint Input” on page
38
).
If a schedule is set, the schedule overrides the Setpoint (see “Schedules Menu” on page 47 ).
If the Setpoint is set to a value higher than 125°F (52°C), a scald warning is displayed. Select OK to
acknowledge the warning and keep the current temperature setting. Select EDIT to return to the Setpoint
screen to enter a lower temperature setting.
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.
