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.
Selections:
None, Aux1, Aux2
Default:
None
Available in Control Modes:
ETV or ETV + TMC,
AUX1/AUX2 = “Temperature”
Menu Path:

System Startup > Control Mode > 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.
