Output Menu
Use the Output menu to enable and configure heat and cool
outputs.
Heat/Cool Output Type
Choose the output type, or disable the heat or cool output.
For more information about each output type, see the Tun-
ing and Control chapter. (If an output is used for process
variable retransmit, the disabled option is not available. To
disable the output, first disable process variable retransmit
for the output. See Heat/Cool Output Retransmit on page
126.)
Values: See Table 5.15
Default: TP (2) for heat, disabled (0) for cool
Modbus Address (Loops 1 to 9): 40137 to 40145 (heat) or
40154 to 40162 (cool)
Parameter Number: 8 (heat) or 9 (cool)
LogicPro Driver: Database
LogicPro Address (Loops 1 to 9): 8.1 to 8.9 (heat) or 9.1
to 9.9 (cool)

Description
Time
Proportioning
TP 2
The output is switched on and off once during a
user-selected cycle time. Within each cycle, the
duration of on versus off time is proportional to the
percent output power.
On/Off on/off 1 The output is either full on or full off.
None disabled 0
The output is not used for control and is available
for another use, such as an alarm output.
Three-Phase
Distributed
Zero Crossing
3P DZC 5
Same as DZC, but for three-phase heaters wired in
delta configuration. For grounded Y configuration,
use DZC instead.
Serial DAC SDAC 4
Use this option if a Serial DAC is connected to the
output. If you set the output type to
SDAC, the con-
troller assigns digital output 34 as a clock line for
the Serial DAC.
Distributed
Zero Crossing
DZC 3
The output on/off state is calculated for every ac
line cycle, which means that the output turns on
and off multiple times per second. Use
DZC with
solid-state output devices or a Dual DAC. Not rec-
ommended for use with electromechanical relays.
