Heat/Cool Output
Choose the manual output power level for this loop. This
parameter is available only for the manual control mode.
Values: 0 to 100% (0 to 1000). Values in parentheses are
for serial communications and LogicPro.
Default: 0% (0)
Modbus Address (Loops 1 to 9): 40273 to 40281 (heat) or
40290 to 40298 (cool)
Parameter Number: 16 (heat) or 17 (cool)
LogicPro Driver: Database
LogicPro Address (Loops 1 to 9): 16.1 to 16.9 (heat) or
17.1 to 17.9 (cool)
Decimal Placement for Modbus or LogicPro: See Dec-
imal Placement for Percentage Values on page 80.
Process Variable
Indicates the value used for feedback after filtering and
scaling. This parameter is read-only.
Values: For thermocouples and RTD inputs, same as the
input range (see Table 5.7 on page 104). For process and
pulse inputs, any value between the Input range low and
Input range high parameters in the Input menu.
Modbus Address (Loops 1 to 9): 40222 to 40230
Parameter Number: 13
LogicPro Driver: CPC400_PV
LogicPro Address (Loops 1 to 9): 1 to 9
Decimal Placement for Modbus or LogicPro: See Dec-
imal Placement for Numeric Values on page 80.

Description
manual 0 The operator manually sets the output power for the loop.
auto 1 The controller automatically controls the outputs.
tune 2
The controller applies a step change and calculates initial
PID parameters for the loop. After the initial tuning, the con-
trol mode changes to adapt to fine tune the loop. This mode
has no effect with on/off control.
adapt 3
The controller automatically controls the outputs and adjusts
the control parameters. This mode has no effect with on/off
control. The mode display blinks when set to adapt but the
process variable is outside the tune band.
