Issue How to make local CPH work on a stand-alone MR-VAV-AX. Environment MR-VAV-AX Cause Even after you select local-CPH in the parameters and connect a contact to the local cph point, the unit probably won't switch modes without further modification. The application is looking for a zero for one mode and something above 1 for the other. Problem is that the factory calibration of the inputs can only be done to within 1 or 2 counts. With the standard conversion coefficient of 5 and 0, you'll still see a value of 5 or 10 for a shorted input. Changing the conversion coefficient wouldn't help because you need an absolute zero. Resolution Even though this is for stand-alone use, you need to connect the unit to an MCI or ISITE Lan. You can leave the address at 0 and set address 0 to MR or ASC in the MCU configuration. Open the ASC editors and update MCI for address 0 and check the point value for local cph with that input shorted. If it doesn't read 0, proceed. Next select Edit, Controller, MR functions. Highlight 0 and hit the Hardware button. These M and Bs are here as a result of the factory calibration. Reduce the B on input 02 (3rd entry down) by one or 2 or even 3 so that the local cph input reads 0 when shorted. When your done with the first one, you can plug in the rest and use the same MCI database provided you leave them all at 0.

Issue Why do the just created lighting circuits not appear in the zones sometimes? Environment I/NET Lighting controller Cause This is a known issue. This has been fixed in later revisions of I/NET. Resolution As a work around, Exit out of the Resident I/O or Summary screen Launching either screen again. Or you can go into the Edit > Controller > Zone Definition and attach the circuits to the zones there.

Issue What are the point address to be used as lighting circuits? Environment I/NET Lighting controller Cause Only certain points can be used to control lighting circuits. These are reserved. Resolution Use points 0-7 with a bit offset of 0-7. You may also use 8-11 for indirect circuits.

Issue What are the point address to be used as lighting zones? Environment I/NET Lighting controller Cause Only certain points can be used to control lighting zones. These are reserved. Resolution Use points 12 to 15 with a bit offset of 0-7

Issue When controlling a circuit point in the summary, the relay does not fire. Environment 7780 Lighting Controller Cause  PICO Fuse on the 7780 controller may be burned out.

Issue What is the difference between Single-pushbutton, dual-pushbutton and latched in a lighting zone? Environment I/NET Seven Lighting Zone Controller Cause Programming lighting controls offers zone options for after hours override. Resolution Single-pushbutton is used when a momentary spring-loaded button is required. You push a button and a closed contact (1) is made. Releasing the button results in a open contact (0) and starts the zone. Dual-pushbutton is a two button switch. Pressing one button gives you a closed contact (1). Pressing another button results in a closed contact (0) on the second input and the zone is turned off. Latched is for when you have a light switch. Flip a switch and it stays on (1). Flip it the other way (0) and it turns off.

Issue What are the different override types on a 7780 Lighting Controller? Environment 7780 Lighting Controller Cause Different override types behave differently. Resolution Permanent means the override will continue indefinitely until: the button is pressed, the switch is moved, or the next time schedule off time happens. Timed means the override will run for a specified number of minutes (0-120).

Issue Correlate which output relays go with which resident I/O addresses in the 7780 Environment 7780 Lighting Controller Resident I/O Editor Cause Wiring diagrams and software designations need to line up for proper lighting control. Resolution On the 7780 the first matrix card controls the bottom eight on each side of the controller giving you your first 16 relays. The bottom front relay on the right side is your first relay. The relay directly behind it is the second relay. This continues up the right side of the controller till you reach the eighth relay, then the numbering jumps to the front bottom left relay and continues with relay number nine. The first relay will be circuit 0000. The second relay will be 0001 and so on. Till you reach 0007. Relay nine will be 0100, ten will be 0101, etc..

Issue What are the differences between DPU EPROM rev 2.21 and 2.22? Environment DPU EPROM Cause On the 2.22 rev, one problem was corrected and an enhancement included.
