Troubleshooting
Normal System Operating Conditions
Base Unit
The following indicates that the base unit is
operating properly:
• The power LED of the base unit is lit.
• All channel LEDs are off if there is no demand for
heat.
• LEDs light up when the corresponding actuators
are activated.
• While waiting for the actuators to activate, the
channel LEDs flash, indicating that they are opening.
Thermostat Display T-75
The thermostat is operating properly when the
display shows the room temperature.
Identifying and Resolving Alarms
and Errors
Alarms
Each LED switches off as the corresponding problem is
solved, and the power LED goes back to its normal state
(i.e., always lit). A blinking LED indicator on the base unit
and interface indicates an alarm or error message.
An alarm icon
appears in the upper right corner
of the interface display to indicate an alarm. The icon
disappears when the message is read, even if the
issue remains.
Note:
See
Table 10-1
, beginning on
page 41
, for
possible alarms and solutions.
Warning:
A qualified professional needs to
install the wiring.
Base Unit Alarm
A blinking power LED indicates an alarm or error
message. To resolve:
1. Remove the base unit cover to see power LED.*
2. If LED is blinking, there is an error.
3. Verify which thermostat is creating the alarm
*If an interface is fitted to the system, alarms
display without the need to take the base
unit apart. The interface displays clearly and
accurately the causes of the various alarms.
Note: See Table 10-1
, beginning on
page 41
, for
possible alarms and solutions.
Each LED switches off as the corresponding issue is
solved, and the power LED goes back to its normal state
(i.e., always lit).
