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
27
.
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.
