SETPOINT
Selections: 40°F to 200°F/ Default: 100°F/38°C (ETV)
(4.5°C to 93°C) 110°F/43°C (HTLV)
Menu Path: /Setpoint
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 33).
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 26).
If a schedule is set, the schedule overrides the Setpoint (See “Schedules
Menu” on page 35).
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.
