PID Pulse 24V Controller
The CXT Controller is primarily designed to control systems with short time constants
and fast response times. This would typically be the control of heat exchangers,
non storage calorifiers or ventilation plant where the sensor is placed directly in the
controlled medium. The CXT operates 24Vac actuators on two or three port valves.
It is capable of operating single or two stage systems.
