Predator Three Zone Loop Application Data Sheet Features Cost effective controller for zone level control of up to three individual rooms or zones. Support up to three Staefa 10K Thermistor room sensor inputs with bypass and setpoint provides optimal control for multiple zones. Expansion platform for picking up remote I/O reduces total installed cost. Four PID loops enable customized control that responds to local sensors and network inputs.
Predator Three Zone Loop Application Data Sheet Sequence of Operation The Three Zone application has been expanded to accept inputs from up to three Talon 10K Thermistor room temperature sensors while continuing to perform general-purpose loop control and I/O expansion routines similar to the standard Four Loop controller. Due to the application flexibility, the sequences are dependant upon the configuration of the I/O and conversion components.
Conversions Conversion components include those components that accept inputs, perform a calculation, then output the result to a PID or output within the application. The Three Zone application includes the following conversion types: Bypass Function: Monitors up to three room temperature sensors and outputs a signal when any of the sensors go to bypass mode. Function: Calculates the minimum, maximum or average value of up to four inputs.
Three Zone Loop Default Configuration By default, the Three Zone controller comes configured to operate a three RTS to valve application.
Occupancy Sensor Use an occupancy sensor as a physical input to function as an “occupancy” or “system on” signal, coordinating the action of the other devices. Variable Frequency Drive Monitoring and control of any directly connected VFD can be accomplished via the Predator. Document No.
Sample Applications Multiple VAV Pressure Dependent System A common air handler cools two VAV rooms: an open plan area with two room temperature sensors (RTS 1 and RTS 2), and a private office with one sensor (RTS 3). Three-position damper actuators in the duct are modulated to provide cool air and maintain the space temperature at the readings on the setpoint sliders. Damper 1 operates in the open plan area, and damper 2 operates in the private office.

Multiple Room Temperature Sensor (RTS) to Valve Sample Application System Description An office space contains three zones that are heated using three hot water radiators with floating motor valve actuators. The controller operates the radiator valves to control the space temperature in the zones to the current space temperature setpoint. Multiple VAV-Pressure Dependent Wiring Diagram Document No.
