20mA range: (40°F/4.5°C to 200°F/93°C) Default: 180°F/82°C
Available in Control Mode: All
Menu Path: /System Startup > Display Unit > Setpoint Input
Description: The ETV Platinum Plus can maintain a setpoint temperature either by
selecting the temperature locally at the control or by receiving a remote setpoint
temperature as a 4–20mA signal from EMS. See “Wiring the 4–20mA Remote
Setpoint” on page 30.
If Remote 4–20mA was selected, the temperature range must be selected using the
4mA and 20mA settings. If the Control Mode is set to ETV or ETV + HTLV options, the
Remote 4–20mA will always apply to the ETV Setpoint. However, if the Control Mode is
set to HTLV, the Remote 4–20mA will apply to the Alarm Limit.
Any signal below 2mA or above 22mA will close the motorized mixing valve in ETV or
ETV + HTLV mode. In the HTLV mode, it will close the HTLV valve and trigger the alarm.
The display will show the message “EMS Open” or “EMS Short” to indicate this status.
AUX1/AUX2 INPUT
Selections: None, Temperature, Switch Default: None
Available in Control Mode: All
Menu Path: /System Startup > Display Unit > Setpoint Input >
AUX1 Input > AUX2 Input
Description:
AUX1 and AUX2 inputs can be configured as a Switch sensor (which
detects open or close conditions) or as a Temperature sensor (which can be used for
anything that is temperature-related, including return and hot supply).
When “Temperature” is selected, the sensor can be used for return compensation
and/or hot supply compensation to provide additional feedback to the control in order
to maintain the desired setpoint temperature.
RETURN COMP.
Selections: None, Aux1, Aux2 Default: None
Available in Control Mode: ETV or ETV + HTLV, AUX1/AUX2 = “Temperature”
Menu Path: /System Startup > Display Unit > Setpoint Input>
AUX1 Input > AUX2 Input > Return Comp.
Description:
If AUX1 or AUX2 input is configured as “Temperature”, Return Comp can
be used (Feed Forward). This is useful for improving the recovery when the Return
temperature changes rapidly.
The sensor must be connected on the cold water return inlet of the valve (after the cold
and return mix) in order to select this option.

NOTE
When Return Comp. is used, a Sensor Probe must be installed. Only one
sensor can be used. The sensor works best when it is 6 feet (1.8 meters) away
from the ETV valve and after the return and cold line meet.
