Analog input
The 4 analog inputs can be used as NTC probe (-50T90 °C; R/T 10 KΩ at 25 °C) or 4/20mA (Impedance = 100Ω)
current signal. They are configurable by pair B1-B2 and B3-B4. The configuration of the type of the input is
automatically set by the CLIMATIC™ 60.
The analog input can be configurable to be used as one of these items:
0) Not set,
1) Water set point desired,
2) Offset set point desired,
3) Free NTC probe.
Digital input
The 4 digital inputs must be used with dry contacts according to the following example. The digital input can be
configurable to be used as one of these items:
0) Not set,
1) Remote On/Off,
2) Remote reset alarm,
3) Swap to second water set point,
4) Force the cooling mode,
5) Force the heating mode,
6) Force the dead zone mode,
7) Force the defrost delay (10min),
8) Disable the circuit 1 (All compressors),
8) Disable the circuit 2 (All compressors),
9) Disable the circuit 1-compressor 1,
10) Disable the circuit 1-compressor 2,
11) Disable the circuit 1-compressor 3,
12) Disable the circuit 2-compressor 1,
13) Disable the circuit 2-compressor 2,
14) Disable the circuit 2-compressor 3,
15) Force the mode A,
16) Force the mode B,
17) Force the mode C,
18) Force the mode D,
19) Force the mode BMS,
20) Status of electrical heaters,
21) Free digital input.
