Good morning,
I purchased an atr444 thermoregulator from one of your specialized distributors.
I want to connect a temperature probe to the input.
Specifically, a 3-wire PT100 probe.
How can I connect it and which are the parameters i should enter?
Thank you.

Re: ATR444 connections and parameter configuration with pt100 sensor
Good morning,
Below are the connection diagrams of the required probe or sensor:
input / terminal 16 - pt100 sensor red wire
input / terminal 17 - pt100 sensor white wire
input / terminal 18 - pt100 sensor red wire
Subsequently, to log in and in order to modify the configuration parameters, proceed as follows:
press "FNC" for 3 seconds;
enter the password "1234";
press "FNC" again to confirm;
use the two arrows to scroll through the parameter groups;
press "SET" to allow modification of the selected parameter;
use the arrows to change its ownership;
press "SET" again to confirm the change;
Below are the parameters to modify to select the 3-wire PT100 probe:
GROUP Parameters A1 - [A.in.1] - Analog input 1
Par. 1 [SEn.1] = Pt100
Press "FNC" once to return to parameter group selection,
Press "FNC" a second time to exit setup mode.
The value of the main setpoint (and alarm setpoint if enabled) can be modified from keyboard as follows:
Change the value on display 2 (bottom row) with up and down arrow keys;
(pressing the "set" key allows you to view the other setpoints, located on display 1 (top row). Display 2, on the other hand, indicates the setpoint type.
Change the digit on display 1 with up and down arrow keys.
To simplify the operation we suggest you to download "MyPixsys" APP which, via NFC communication, will allow to view and modify the setting parameters from your mobile phone or tablet.
