WIND COLD WATER COLD ON DEMAND SELECTION
The circulating fluid from the pump is cooled by the customer’s equipment and then returns to the thermostat. The circulating fluid passes through the refrigeration circuit, reaches the set temperature, and is then output to the customer’s device side through the thermostat.
CASCADECOMMUNICATION REMOTE OPERATION
According to the serial communication remote control signal input and output, one of the contact inputs can be remotely operated using serial communication for remote operation, and the other is used to monitor the flow through the flow switch and read the alarm output.
Alarm, operating status (start, stop, etc.)
Signal output
The alarm and status inside the temperature controller can be divided into 3 output signals according to their content.
