Output Group (G.OUT)
The Output Group includes parameters used to
configure the general operation of the control outputs.
OUT1 Control Mode (CNT1)
The control output mode of OUT1 can be selected
from On/Off (ONOF) or PID.
OUT2 Control Mode (CNT2)
The control output mode of OUT2 can be selected
from NONE, On/Off (ONOF) or PID.
Output Action (O.ACT)
The operation in which the control amount increases
when the deviation (PV - SV) is positive is referred to
as a direct action, and the operation in which the
control amount increases when the deviation is
negative is referred to as a reverse action.
You can select direct or reverse action only when
OUT2 Control Mode (CNT2) is set to NONE
Heating & Cooling Control Mode
When OUT2 is set to either ONOF or PID, the
controller will automatically enter heating and cooling
control mode.
In heating and cooling control mode, the Output
Action O.ACT parameter is disabled. OUT1 is always
the heating side control output, and OUT2 is always
the cooling side control output.
Disable Heating & Cooling Control
To disable Heating & Cooling control mode, set OUT2
Control Mode (CNT2) to NONE. When this is done,
the Output Action (O.ACT) parameter is used to
selecting heating (reverse) or cooling (direct) control
for OUT1.
Control Period, Heating (CP)
This parameter is used to set the on/off cycle time of
OUT1 when in OUT1 Control Mode (CNT1) is set to
On/Off (ONOF) control mode. This parameter is only
used when OUT1 is a relay or SRR output.
When using a mechanical relay for control, set
the control period to at least 20 seconds.
When using SSR output for control, set the
control period to at least 1 second.
Control Period, Cooling (CPC)
This parameter is used to set the on/off cycle time of
the OUT2 relay when in OUT2 Control Mode (CNT2)
is set to On/Off (ONOF) control mode.
When using a mechanical relay for control, set
the control period to at least 20 seconds.
When using SSR output for control, set the
control period to at least 1 second.
