5.4 LED message code
„
Continuously green
At least one relay is closed.
Regulation operating normally (System Operating). Solar system
Operating. The temperature of the hot water tank (parameter TS)
increases.
„
Continuously red
All relays are open.
The installation is stopped. The solar collectors are not hot enough
(parameter TC) to enable operation.
„
Flashing green/red
- Initialisation phase
- Sensor fault.
See chapter Sensor fault.
- The installation is in manual mode.
For automatic operation, set parameter MM to 4.
- Maximum tank temperature exceeded.
The hot water tank has reached the set temperature and the
installation is in overheating safety mode or in cooling mode.
- Maximum temperature of the solar collectors exceeded.
The installation is in safety mode. It remains in this mode until the
temperature of the solar collectors has fallen back below the
maximum temperature.
5.5 Measured values and adjustment parameters
 The regulator has a safety system that cuts off the tank at
temperatures of over 80°C.
