5.11 0-10V analogue input
For the thermostat input to operate correctly, ensure that the jumper on CN4 is set at 'A'.
Applying a voltage in the range 0-10V to the T/A input relative to 0V will cause the controller to move the
actuator to a position which assumes 1V==10% opening.
In operation, the controller calculates the required position using the equation (input voltage)/10*18,
where the 18 seconds element can be adjusted at the factory be S E Controls.
The exception to this is if the input voltage is set to 0V. In this case, the controller will apply power in the
close direction to the actuator but will time off after a period of 180 seconds (factory adjustable) to
guarantee the fully closed position is reached.
By default, the 0-10V input is assumed to be an automatic control but can be adjusted at the factory by
SE controls to be a manual control.
5.12 Auto/Manual input
Connecting AUT to 0V will place the controller in automatic mode. Breaking the connection will place the
controller into manual mode.
