Index Parameter Description
Ea01 Type of control One temperature probe
Ea05 Modulating control
Set:
temperature set point (0-100 °C) (32-212°F)
differential (2-20°C) (3.6-36°F)
Minimum production (25-100%)
Maximum production (25-100%)
Ec01 Type of main probe Select from: 0-1V, 0-10V, 2-10V, 0-20mA, 4-20mA
Tab.4.p
Note: when using Carel 0-10V probes, connect the probe power supply +(G) to terminal “14” on the
terminal block “T” inside the electrical panel, rather than terminal 3U.

CONTROL WITH ONE TEMPERATURE PROBE AND LIMIT PROBE
l short-circuit terminals 7U and 8U (jumper) to enable production; alternatively connect terminals 7U –
8U to a remote contact (e.g.: switch, timer,...);
l connect the main active room probe to terminals 1U, 2U (GND) and 3U (+12Vdc);
l connect the active limit probe to terminals 5U, 3U (+12Vdc), 6U (GND);
l to enable control, set:
