Issue
DC1100 / DC1400 displays message "No Sensors Connected" or displays temperature values that are not representative of the temperatures being sensed.
Environment
DC1100 / DC1400 Discrete Controller and associated Sensors.
Cause
DC1100 / DC1400 is connected to Sensors having incompatible resistance range.
The resistance range of those Sensors compatible with the DC1100 differs to that of the resistance range of those Sensors compatible with the DC1400
"No Sensors Connected" message may appear in the Controller display as a result of the Sensors connected having a resistance that is out of range compared to that of the resistance range that the Controller Sensor Inputs are designed to recognise.
Resolution
Check Sensor type connected to Controller.
DC1100 Controller is compatible with the following Sensors :-
STC 600 D Contact Temperature Sensor (Original Drayton Sensor = A704)
STO 600 D Outside Air Temperature Sensor (Original Drayton Sensor = A702)
STP 600 D Pipe Temperature Sensor (Original Drayton Sensor = A703)
STR 600 D Room Temperature Sensor (Original Drayton Sensor = A701)
DC1400 Controller is compatible with the following Sensors :-
STC 600 Contact Temperature Sensor (Original Satchwell Sensor = DST)
STO 600 Outside Air Temperature Sensor (Original Satchwell Sensor = DOT)
STP 660 Pipe Temperature Sensor (Original Satchwell Sensor = DWT)
STR 600 Room Temperature Sensor (Original Satchwell Sensor = DRT)
