SELF-DIAGNOSIS PROCEDURE
This procedure allows you to check whether the individual
outputs of the controller function correctly.
To run the procedure, follow the directions below:
■
switch the thermostat
off
■
push the at the same time
■
use the keys to change the value on the display
until arriving at the password for self-diagnosis (
030
) and
press . The following screen will be displayed:
■
press the button to switch on the various thermostat
outputs in sequence.
Symbol Actuation Terminals
Extra low speed N-V0
Minimum speed N-V1
Medium speed N-V2
Maximum speed N-V3
Valve N-Vc
Heater / Second valve N-Vh
CO1 Digital 1 output C012-C01
CO2 Digital 2 output C012-C02
AO1 Analog output 1 = 10V COM-101
AO2 Analog output 2 = 10V COM-102
The electronic controller outputs can be checked one by one
either by observing the respective component (valve, fan..)
or verifying whether a voltage of 230 V is present at the cor-
responding terminals.
■
to exit the self-diagnosis procedure press (after a
few minutes the thermostat will automatically exit in any
case).
