Button: MENU/<System Settings>/<More Settings>/<Modulating Settings>/Gain

• The Gain adjusts the aggressiveness of the modulating PID logic. It controls how much

modulation is changed when the system temperature is different from the Set Point.

• A Gain of 0 is a good starting point for all systems.

• If during normal load conditions, the system temperature tends to oscillate signicantly,

decrease the Gain by two numbers (for example, from 0 to -2). Wait for at least 15 minutes

before evaluating how the change has affected the system.

• If during normal load conditions the system temperature tends to remain consistently below

the Set Point (or consistently above the Set Point), increase the Gain by two numbers (for

example, from 0 to 2). Wait for at least 15 minutes before evaluating how the change has

affected the system.

Button: MENU/<System Settings>/<More Settings>/<Modulating Settings>/Lag Delay

• The Lag Delay requires the lead stage to remain at 100% modulation for the full period of

the Lag Delay before the lag stage can be activated. For example, if the Lag Delay was

set to 10 minutes, the Lead Stage must remain at 100% modulation for the full ten minutes

before the lag stage could be activated. The Message Display Line will display Lag

Delay and the remaining time.

• The Lag Delay is useful in installations where one unit should usually have enough output

to hold the load unless it fails or load conditions become extreme.

• The Lag Delay overrides the Modulation Start % selected for each stage. Regardless of

that setting, the previous stage must reach and stay at 100% before the lag stage can be

activated.

• The full Lag Delay must elapse regardless of what happens to the system temperature.

Therefore, set the Lag Delay to 0 minutes to achieve smooth operation.

• Note that if Parallel was selected as the Modulation Mode (See "Modulating Logic

Overview" on page 4), this value must be set to 0 minutes to avoid having the lead boiler

going to 100% modulation prior to ring the lag boiler.

Button: MENU/<System Settings>/<More Settings>/<Modulating Settings>/Soft-Off Delay

• When a boiler is no longer needed, the Soft-Off keeps that boiler in Low Fire prior to

turning it off.

• The display will show a percent that is equal to the Ignition % for the stage in Soft-Off

delay. That number will blink for the Soft-Off delay period.

• If during the Soft-Off delay period the TempTracker mod+ Hybrid needed that stage to turn

back on, the stage will be released from the Soft-Off delay and resume normal operation.

• On a Shutdown initiation or Tstat termination any stage that was On will go into Soft-Off

delay before fully turning off.

When using Soft-Off and Last Stage Hold, the last boiler will not turn off until both

parameters have elapsed. In this case, Soft-Off will start after the Last Stage Hold.
