Description
The NPC-602-COM is a Proportional/Integral Compensator with advanced features. Setpoint is calculated internally with respect to outside temperature using user defined Heating Curve. Calculated Setpoint can be trimmed up to ±20°C using External Pot. Digital Remote can used to display Flow Temperature and Calculated Setpoint only. The compensator has separate analogue 0-10VDC proportional outputs for heating and cooling so requires no configuration for outputs prior to use. The unit offers individual Proportional band and Deadband adjustment of each output and separate adjustment of Heating and Cooling Integral Time. The compensator is designed specifically to control Damper Actuators, Thyristor Controllers, Relay Modules etc.

Features
- Two Analogue outputs, 1 Heating output and 1 Cooling output.
- Digitally calibrated 0-10VDC proportional outputs.
- Separate outputs for Heating and Cooling, i.e., Plug n Play, no configuration required.
- Full Proportional + Integral.
- Separate Integral Time for Heating and Cooling allowing it to be used for Heating and Cooling with or without Integral.
- Analogue output value in (%) is displayed on LCD. All Proportional outputs have Blinking LEDs with a Blinking rate directly proportional to Analogue output. e.g. output with 0% is completely off while for 100% solid lit.
- User friendly Back-lit 16X2 LCD Display with 5Way Navigation Switch.
- Temperature range from -5°C to +95°C with a resolution of 0.1°C for Flow and Outside Temperature.
- Heating Curve design option using Flow High and Flow Low temperature values.
- Setpoint is calculated internally with respect to outside temperature using user defined Heating Curve.
- Temperature Sensors offset feature. With this feature, individual offset of ±5°C with a resolution of 0.1°C can be adjusted to eliminate error for Flow and Outside Temperature Sensors.
- Night Set-back option. Indication is provided on LCD when Night Set-back is activated.
- Choice of Remote Setpoint input, i.e. two-wire Digital and Analogue:
- Digital Remote requires no external power therefore Power and Data is Transmitted/Received simultaneously over a pair of wires with NORPOSH Intelligent Communication Protocol with CRC (checksum) on both side for error free Flow Temperature and Calculated Setpoint Display.
- Analogue input is user selectable for Resistance:
- Resistance input can be selected from menu for 0-10KΩ, 1-11KΩ, 0-5KΩ and 560-10560Ω. Variety of pre-defined External Pot ranges gives an option to use different available POTs in the market.
- 24VAC/DC Power input.
- Din-rail PCB Holder.
