To set Retransmission to positive/negative slopes (a Retransmission board must be installed first): In 【Initial Setting Mode】 set
the
parameter, the last digit (Y) of xxxY indicates when Y=0 positive slope; when Y=1 negative slope.
To adjust the lower limit of Retransmission:
a、 Make sure the slope of Retransmission is positive.
b、 Set lower limit value larger than the display value: In 【 Initial Setting Mode】 set the value in
(PV).
c、 Input the analog value to meter, check the meter and adjust the analog input value: In 【Regulation Mode】 , enter the new value
into
. For example, if the range is 4~20mA, the new value will be 4mA.
To adjust the upper limit Retransmission:
a、 Make sure the slope of Retransmission is positive.
b、 Set upper limit value smaller than the display value: In【Initial Setting Mode】set the value in
value (PV).
d、 Input the analog value to meter,check the meter and adjust the analog input value: In 【Regulation Mode】 , enter the new value
into
. For example, if the range is 4~20mA, the new value will be 4mA.
Check the Firmware Version and Output Type
When the temperature controller is ON, the PV and SV display will shows firmware version, output type and accessory functions in first 3
seconds.
PV (first 3 digits) indicates the firmware version. Ex: 110 indicates firmware version V1.10.
th
PV (4
digit) indicates the function of accessory 1.
C: RS485 Communication
SV (frist 2 digits) indicates the output type of OUT1 and OUT2.
N: No function
V: Voltage pulse output
L: Linear voltage output

SV (3
digit) indicates the function of accessory 2.

Selection for Heating/Cooling/Alarm/Dual Loop Output Control
CND3 series offers 1 set of Output Control (OUT1) that is built-in internally and 2 sets of Alarm Output(ALARM1 and ALARM2). User
nd
can also purchase a 2
set of Output Control (OUT2) or a 3

Cooling + Alarm 3(C1A2) in 【Initial Setting Mode】.
OUT2 output types in relay, voltage pulse, analog current, linear voltage and SSR output can all be used for ALARM ON-OFF. For
example, OUT2 is set to analog current output. It outputs 4mA when alarm is OFF and outputs 20mA when alarm is ON.
nd
When the 2
set of output control (OUT2) is used as dual output control, set
Heating/Cooling(H1C2) or Cooling/Heating (C1H2) control mode in【Initial Setting Mode】.
The Dead Band parameter
in the diagram follow. The purpose of Dead Band function is to reduce the energy wastage of frequent heating/cooling actions. For
example, if SV = 100 degree and
