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.

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.
