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 42.
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 + TMC options, the Remote 4‐20mA will always apply to the ETV
Setpoint. However, if the Control Mode is set to TMC, 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 + TMC mode. In the
TMC mode, it will close the TMC valve and trigger the alarm. The display will show the message "EMS Open" or
"EMS Short" to indicate this status.
