05 STARTUP
HOT SUPPLY COMP.
Selections: None, Aux1, Aux2 Default: None
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 Default: No
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 17.
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).
LIMIT VALVE POS.
Selections: 0% to 100% Default: 50%
Menu Path: /System Startup > Display Unit > Setpoint Input> AUX1
Input > AUX2 Input > Return Comp. > Hot Supply
Comp. > Flow Switch = Yes > Limit Valve POS.
Description:
When Flow Switch = Yes and no flow is detected, the control
will adjust the mixing valve to the defined opening percentage if the valve is
currently open more than the set value. If the current valve opening percentage
is less than the set value, the valve will remain in its current position.
For example, if Limit Valve POS. is 30% and no flow is detected when
the current valve opening percentage is 50%, the control adjusts the
mixing valve down to the 30% open position. If the current valve opening
percentage is 20% when no flow is detected, the valve will remain at the
20% open position.
