• Twelve outputs are supported. These functions are assigned to control
outputs 1 and 2, and auxiliary outputs 1 and 2.
• Restrictions on assignment destination are placed on some of the out
puts.
• The following table shows where outputs may be assigned to.

With control output (cool), the conditions for switching from standard control
to heating and cooling control are reached when the output function is assigned
at the cooling side during heating and cooling control.
In other words, heating and cooling control is carried out when control
output (cool) is assigned, and standard control is carried out when out
put is not assigned. For details on heating and cooling control, see Chap
ter 4 Applied Operation/4.1 Selecting the Control Method (page 4 2).
• Factory settings are as follows:
control output 1 = Control output (heat)
control output 2 = Alarm 1
auxiliary output 1 = Alarm 2
• Output assignments are set in the control output 1 assignment", con
trol output 2 assignment",  auxiliary output 1 assignment" parameters
(setup mode).
• Direct operation" (or normal operation) refers to control where the ma
nipulated variable is increased according to the increase in the process val
ue. Alternatively, reverse operation" refers to control where the manipu
lated variable is decreased according to the decrease in the process value.
For example, when the process value (PV) (temperature), is lower than
the set point (SP) (temperature), in a heating control system, the manip
ulated variable increases by the difference between the PV and SP val
ues.
Accordingly, this becomes reverse operation" in a heating control sys
tem, or alternatively, direct operation" in a cooling control system.
• Direct/reverse operation is set in the direct/reverse operation" parame
ter (setup mode). The direct/reverse operation" parameter is factory
set to (reverse operation).
