Prolon PL-M2000-CHL : Advanced Chiller Controller, 5 Digital Outputs, 3 Analog Outputs, 9 Universal Inputs, Economizer/DCV Control, 7 Day Scheduling, Duct Static Pressure with Bypass Damper or Supply Fan VFD, Modbus RTU (RS485)
The M2000 CHL Chiller controller is designed to control a variety of different chiller units and systems, and can be used for both air cooled chillers and water cooled chillers. The on-board microcontroller offers precise digital control to maximize performance. The available control sequences are fully configurable, either locally or remotely, using free software. The M2000 CHL offers a variety of functions such as outdoor reset for the chilled water supply temperature, lead-lag sequences for pumps and chiller stages, pump VFD control, safety limits and more.
Features
- Pump activity based on outside temperature or schedule (or both)
- Configurable pump exercise sequence for extended periods of inactivity
- Supply water setpoint reset based on outside tempera- ture, return temperature or demand
- Control up to 4 chiller stages (multiple chillers or a single multistage chiller or combination)
- Various lead-lag sequences for the pumps and chillers
- Chiller lockout or stage down based on entering or leaving condenser water temperature limits
- Can modulate a VFD for each pump to maintain a fixed water pressure setpoint
- Internal clock with configurable schedules and calendars
- A manual/off/auto switch for each of the eight outputs
- Remote monitoring and configuration with FREE Prolon Focus software
- Standalone or networked (up to 127 nodes)
- 5 digital outputs and 3 analog outputs equipped with resettable fuses
- Built-in protection sequences with configurable tempera- ture limits and minimum delays
- Dedicated input that can deactivate the pumps upon contact closure
