From the main menu decreases the value of set point displayed in the large field. From the other menus displays the variables or the
parameters or alternatively changes the value if first pressing SET.
Important: the operating mode can be changed with the instrument on or off. When the mode is changed, the user is asked whether to use the
default parameters for that mode. If yes, press SET, tasto UP and SET again. Otherwise press PRG to exit.
TABLE OF ERRORS
Code displayed Description
ALE
External alarm generated by the digital input. If set from parameter
EE Parameter memory alarm. Stops control of the instrument until the default parameters are loaded
E1 Inside temperature probe alarm
E2 Outside temperature probe alarm
Eth Digital temperature or humidity sensor alarm (only in the models where featured)
Ert Real time clock alarm (only in the models where featured)
ELN No link: control of the outputs by supervisor has been set, but there is no connection (parameter Lin = on)

CONNECTIONS
The installer must connect the “CLIMA” regulator ( see fig. 4 ) to the electric control board of roof top, with n. 6 cables ( 4 cables when
operating with roof top AMC..XR..), and keeping separate the tension cables from the analogue output 0-10V ones for the RX burner
proportional regulation . The “CLIMA” regulator must be installed not more than 30 m. from the warm air heater X or roof top, as cable length.
• digital input:
– non-insulated version: direct connection of the voltage-free contact; contact closing current: 3-5 mA .
– insulated version with external power supply and 24 Vac contact: class II safety external power supply separated from the 24 Vac of the
instrument (Fig. 4b)
• Outside probe connection with standard Carel probes ( 10K 25°C B=3435):
– maximum length: 30 m with min cable cross-section 0.5 mm 2 .
• Digital input connection: maximum length 10 m, min. cable cross-section 0.5 mm 2 .

• Relay output:: to use the instrument in compliance with UL-873, a load with a maximum voltage of 24 Vac, class II, can be connected.
• UL instructions for the connections:
- Use 75° copper (CU) conductor and wire size No. 22-14 AWG, stranded or solid
