6.2 EDIT THE SET-POINT FROM 0-10V INPUT OR FROM RATIOMETRIC INPUT
Another type of adjustment allows you to edit the setpoint by adding (or subtracting) a value depending on the 0-10V input (if enabled). To
enable the function, set H22=40 , and, if appropriate, edit the value of the parameter b15 (range 0-10), keeping in mind that if b20 =0, 0-10Volt
input, if b20 =1, ratiometric input.
- b20 = 0 with input at 0 Volt, the current setpoint: (Coo/Hea) setting – b15/2
- b20 = 0 with input at 5 Volt, the setpoint will be that set (Coo/Hea)
- b20 = 0 with input at 10 Volt, the current setpoint: (Coo/Hea) s b15/2

The signal must be applied to terminals X-22.1 and X-22.2- (see wiring diagrams).
- b20 = 1 with input at 0%, the current setpoint: (Coo/Hea) setting – b15/2
- b20 = 1 with input at 50%, the setpoint will be that set (Coo/Hea)
- b20 = 1 with input at 100%, the current setpoint: (Coo/Hea) s b15/2

Through the terminal block, connect X-22.1 and X-22.2, while for +5V connect it directly to pin 3 of CN7 (pin 28 of the controller).

NOTE : in “cooling” mode, having considered that the default cooling setpoint is 7°C, the parameter b15 must not have a value of 6 or higher to
prevent the new setpoint set by 0-10V input from being lower than the antifreeze triggering threshold (4°C).
7. CIRCULATOR
The circulator of the heat pump can be set in the following operating modes:
- operation on call by temperature controller
- operating on call by temperature controller with periodic activation;
