DESCRIPTION: Plus or minus temperature deviation from setpoint in degrees.
10. Remote Setpoint (Optional)
There are two inputs; 4-20mA and Volts which can be fitted in place of digital communications.
It is not necessary to fit an external burden resistor to the 4-20mA input.
If the 4-20mA remote setpoint input is connected and valid (>3.5mA; < 22mA) it will be used as the main setpoint. If it is not
valid or not connected the controller will try to use the Volts input. Volts sensor break occurs at <-1; >+11V. The two inputs are
not isolated from each other.
If neither remote input is valid the controller will fall back to the internal setpoint, SP1 or SP2 and flash the alarm beacon.
Be sure to set the Remote Hi Limit and Remote Lo Limit in the SETPOINT List.
