Causes and solutions
Check that:
• There is no programming enabled.
• The MASTER thermostat is not OFF.
• ECO temperature is not enabled.
• The external power supply of the thermostat (12VDC, 0.3VA) is working
correctly.
• The last zone which remains open always closes with a 30-second delay. This
is not an anomaly, occurring only in the last open zone.
• Faulty power supply.
• If the locked indicator is lit up (padlock), this thermostat is configured as the
Slave and the keys pressed do not have any functions. Carry out the operations
in the Master thermostat.
• If weekly programming is not enabled, check with your installer for unlocking.
Turning off the whole system
The complete system can only be turned off using the
MASTER thermostat:
1 Press the "POWER"
continuously, until only the word OFF appears on the
display and the zone indicator, as can be seen in the
following figure:
