Manual mode.
In manual mode, the controller does not activate the algorithm, and the number and type
of attached devices are dependent on the user, who takes responsibility for the correct
operation of the equipment. The system temperature is displayed on the main screen.
On entering manual mode, all connected devices are stopped automatically. When the
controller is operating in manual mode, this is indicated by a red light in the top part of the
button
.
5.4.
Alarm mode.
The controller will go into alarm mode when one of the sensors fails, the cable is broken or a
sensor is disconnected - in which case the controller will indicate that such a sensor is required.
During an alarm, all pumps are switched off (with the exception of the boiler overheating alarm
AL6). When the fault is repaired the controller returns to the mode it was in before. The controller
will not go to alarm mode when a sensor fault is repaired. Any changes to components should be
performed while power to the controller is disconnected. The controller exits alarm mode
automatically when the alarm is AL12 (overheating of the boiler) and the outlet temperature drops
below the 'F17' value - 4 ° C.

system operation measurements using LEDs on the display, and editing the parameters
customisable by the user.
