- The document provides an agenda for MAXVU technical support training, covering an overview of MAXVU, control recap, modes and configuration. - MAXVU has universal inputs, relay and SSR outputs, RS485 option, and 1/16 DIN size. It supports thermocouples, RTDs, and linear inputs but not all thermocouple and RTD types. - The training covers MAXVU modes including user mode, setup mode, and advanced configuration mode accessed via passwords. Configuration software allows programming via PC.

- 13. PV Differential Set-Point Output turns on below differential band Time Output turns off above differential band A common home thermostat operates with this type of control Like West the Differential sets the allowable deviation above and below the setpoint ON/OFF Control On – full power (100%) / Off – no power (0%)
- 14. Set-point 100% power 0% power PV Time *Offset Proportional band * In order to remove the offset above you need to bias the manual reset. Proportional Only Control
- 15. PV Proportional bandSet-point 100% power 0% power Time Conventional P.I.D. Control Within the proportional band the power output is varied by the controller

- 18. Corrects proportional control offset error •Too short - overshoots and oscillates •Too long - slow warm-up and response Too short Too long Integral Time (seconds)
- 19. Suppresses overshoots & effects the response time to disturbances •Too short - slow warm-up/response •Too short - under corrects •Too long - oscillates and over corrects Too short Too long Derivative Time (seconds)
- 21. MAXVU Language • Heat instead of Primary (or SP1) • Heat Proportional Band • Heat Power Limit • Cool instead of Secondary (or SP2) • Cool Proportional Band • Cool Power Limit • Pre-Tune • Tune at Setpoint No control direction parameter needs to be set - Heat, or Cool, or Both available
- 22. MAXVU Simplified Operation – Setup Mode • Appears on first power up, or when reset to factory defaults & then power cycled • Most applications need only a few settings • Quick set-up • Short set-up mode reduces stepping through unused settings • Scaling only visible when using linear input Setup Mode Setup Mode lock code Input Type Input Units Process Display Resolution Scale Upper Limit (linear input only) Scale Lower Limit (linear input only) Output 1 Usage Output 2 Usage Output 3 Usage Alarm 1 Adjust Alarm 2 Adjust Set-point Adjust Automatic Tuning Start/Stop Note: Alarm Type is not visible
