28 ETS Installation and Operation Manual
Aux1/Aux2 Input
Selections: None, Temperature,
Switch
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).
Return Comp.
Selections: None, Aux1, Aux2
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.
Hot Supply Comp.
Selections: None, Aux1, Aux2
Menu Path: /System Startup > Display Unit > Setpoint Input> AUX1 Input >
AUX2 Input > Return Comp. > Hot Supply Comp.
Description:
If AUX1 or AUX2 input is configured as "Temperature", Hot Supply Comp can
be used. This is useful for improving the recovery when the Hot Supply
temperature changes rapidly.
Flow Switch
Selections: No, Yes
Menu Path: /System Startup > Display Unit > Setpoint Input> AUX1 Input >
AUX2 Input > Return Comp. > Hot Supply Comp. > Flow Switch
Description:
All mixing valves require constant flow for accurate temperature control. The ETS can accept a dry‐contact
Flow Prove input through terminals 25 and 26. See "Wiring the Flow Prove" on page 42.
When Yes is selected and no flow is detected, the control will adjust the mixing valve down to the Limit
Valve POS. setting (if the current valve position is greater than the Limit Valve POS. setting), or leave the
mixing valve at its current position (if the current valve position is less than the Limit Valve POS. setting).
