In this example, the boilers’activation and their power control would be made as shown below:
10.2 External control signal 0…10 V to regulate start-up and power modulation of each boiler
Each boiler can receive and process an external signal 0…10 V.
The external signal 0…10 V will transmit to the boiler a set-up temperature value.
The signal 0…10 V must be connected to the terminals shown inside the boiler.
The linear characteristic is defined by 2 fixed points. The setting uses 2 pairs of parameters for function value
and voltage value (F1/U1 and F2/U2).
