Q. Why have I got no rooms displaying any temperatures?
A. Usually this is one of two things:
1. There is a wiring issue which is stopping the Sensor communicating with the Wiring Centre
2. The order in which the Wiring Centres were added does not match order of the added Sensors.
2. The order in which the Wiring Centres were added does not match order of the added Sensors.
SOLUTION 1
You shoud check:
- The connections on the back of the Sensors (b+ and b-)
- The connections on the Wiring Centre C2 (b+ and b-)
- Check the Links are correctly placed in the last sensor and on the Wiring Centre C2 (i f)

This guide provides all the information you'll need about the sensor bus
SOLUTION 2
You shoud check:
- Check your Appendix Table is filled out correctly
- Perform a Modbus reset and add the Wiring Centres again making sure to follow the Appendix Table precisely
TOP TIP: When you add the sensors to the Wiring Centres this creates a sequential list on the Control Hub (you'll see the rooms added with a number next to them). Make sure you have the serial numbers for every room and add all the snesors for one Wiring Centre at a time (i.e. don't add sensors in a random order)
