・PV difference
input，Delay timer spec available
| |
PV difference input and delay timer spec are provided.
・PV difference input: Control is performed using the PV (CH1
PV-CH2 PV=PV).
・Delay timer: Timer output occurs using the DI (digital input). |
| |
PV difference input application
The heat source (heater) is controlled to maintain a constant
temperature difference between 2 points(A, B).
(e.g.) No condensation, defogging |

space
| |
As 2-unit function can be used with one unit,
mounting space can be reduced by half. |
| |
|

Heating/Cooling control output
|
If CH1 cooling output is selected during CH2 function selection,
the unit will be of 1ch Heating/Cooling control output specification.
So CH1 will match OUT1 (Heating output), and CH2 will match
OUT2 (Cooling output ) of CH1.
OUT2 proportional band: 0.0 to 10.0 times OUT1(CH1) proportional
band (ON/OFF action when set to 0.0)
OUT2 integral time，OUT2 derivative time: The same as those
of OUT1(CH1) integral and derivative time
OUT2 proportional cycle: 1 to 120sec
Overlap/Dead band: Thermocouple, RTD input: -100.0 to 100.0()
DC current, voltage input: -1000 to 1000 (The placement of
the decimal point place follows the selection)
OUT2 ON/OFF hysteresis: Thermocouple, RTD input: 0.1 to 100.0()
DC current, voltage input: 1 to 1000 (The placement of the
decimal point place follows the selection)
OUT2 high limit: 0 to 100% (DC current output type: -5 to
105%)
OUT2 low limit: 0 to 100% (DC current output type: -5 to 105%)
OUT2 action mode: Air cooling (linear characteristic), Oil
cooling (1.5th power of the linear characteristic), Water
cooling (2nd power of the linear characteristic)
Selectable by front keypad
Control output: Refer to the "Control output" section.
