CONTROLOPERATION
:
Input1 –RemoteTemperature Sensor
The controller has an integral sensingdevicemounted internally. It is alsopossible to install a
remote roomor duct return sensor at different locations. Seewiring diagram.
Note#1
: The remote sensor should bePT1000 (Refer Accessories)
Input2- Emergency Input
Input2 is to connect with anOn/Off dry contact for systemerror or emergency interlock control. If
the contact is close, the controller will automatically closeall output (or open to themaximum
position in reversemode) and cut off the power. The controller can only be restartedmanually.
Note#2
: If youdon’t want to use the interlock function/emergency input please use a jumper wire
to connect input2 (terminal no.5) and neutral port (Terminal no.3), seewiring diagram.
Output1-ModulatingAnalogOutput (2 to10Vdc or4 to 20mA)
Output1 ismodulatingP+I analog2 to 10Vdcor 4 to20mA. It can be selected bySelector
switch. The output signal is normal mode (2 to 10Vdc or 4 to 20mA) or reversemode (10 to
2Vdc or 20 to 4mA) selectable.
Output2-On/Off digitalOutput (2A, 24Vac)
Output2 is digital output with 24VAC2AContact rating, nominal capacity. It providesOn/Off
control for electricheater, on/off valveactuator or fan etc.
Output2 can provide limitation control throughpre-setting a separate temperature limitation.
