Set the CN 2110 controller’s configuration via mechanical dip switches, located on the bottom of the unit. Factory settings are J, TC, °F, and PI Control. Switches are easier to set before mounting.
To change the switch settings, first disconnect all wiring and power from the unit. Adjust switch settings as follows:
|

Switch | Function | Options | Setting |
A | Thermocouple | J or K | J |
B | Input Type | TC or RTD | TC |
C | Temperature Units | °F or °C | °F |
D | Control Type | PI |
If input type is thermocouple, switch A selects either thermocouple type J or K.
Switch B selects input type thermocouple or RTD (resistance tempera- ture detector). Note: If RTD is selected, switch A is ignored.
Switch C selects temperature units °F or °C.
Switch D selects either PI
