Prolon PL-C1050-BLR : Boiler Controller, 4 Digital Outputs, 1 Analog Outputs, 3 Analog Inputs, 1 Digital Input, Modbus RTU (RS485)
The C1050 BLR boiler controller is designed to control a variety of different boiler units and systems. The on-board microcontroller offers precise digital control to maximize performance. The available control sequences are fully configurable, either locally or re- motely, using free software. The C1050 BLR uses PI (Proportional-Integral) control loops to optimize boiler management and offers a variety of functions such as outdoor reset for the supply water temperature, lead-lag sequences for pumps and boiler stages, optional three-way valve sequence, safety limits and more.
Features
- Pump activity based on outside temperature or call for heat (or both)
- Configurable pump exercise sequence for extended periods of inactivity
- Supply water setpoint reset based on outside temperature
- Control up to 2 boiler stages (multiple boilers or a single multistage boiler)
- Control 1 modulating boiler with optional backup stage.
- Various lead-lag sequences for the pumps and boilers
- Offset the supply water setpoint based on a network received demand or occupancy
- Optional control sequence for a three-way valve
- Remote monitoring and configuration with FREE Prolon
- Focus software
- Stand-alone or networked (up to 127 nodes)
- Proportional integral (PI) control loops maximize perfor- mance
- 4 digital outputs and 1 analog output equipped with resettable fuses
- Built-in protection sequences with configurable tempera- ture limits and minimum delays
