Heating Cooling Controller With Modbus Communication
SKU: SXS-050
Multistage Modbus heating and cooling controller with backlight LCD display. 3 analogue 0..10V outputs, 2 digital outputs, 1 external auto-detect sensor, 1 digital input, built-in temperature sensor.
The SRC-100 series controllers have been designed for zone heating and cooling control. The controllers have 3 analogue 0..10Vdc outputs and two digital outputs that can be configured for heating and cooling control. The controllers can operate as Proportional Only or as Proportional + Integral Controllers.
The controller can have up to 2 heating and cooling stages. The analogue outputs can be individually configured for any of the heating/cooling stages and digital outputs can be configured as 3-point, PWM (thermic) or On/Off control.
The controller setpoint can be adjusted -/+3°C (default) by rotating the potentiometer. The setpoint centre and setpoint limits can be adjusted in the configuration mode or via the configuration tool.
On the models without the display; red and blue LEDs indicate the controller operation in heating or cooling mode. In the display models, the display shows the heating and cooling modes, the current active actuator position, and the current temperature reading. When the setpoint is adjusted, the backlight is switched temporarily on and the current setpoint is displayed.
The controllers have built-in Modbus RS-485 communication for connection to BMS systems.
