This function takes priority over all others, and is the first to be implemented by the
controller. When the function is activated, the temperature of water in the boiler is raised to
70 C and maintained for ten minutes. The function can be activated at any time by the user. If,
after 120 minutes following activation, the temperature is not reached, the controller
switches off the function and displays text information showing that the function could not be
implemented. This is only available in the second configuration.

GA03HA room panel
The GH21TA controller is adapted to communicate with GECO’s GA03HA room panel,
enabling an easy overview of the boiler from the comfort of your home.
Connecting the GH21TA controller to the GA03HA room panel allows:
•
Changing the boiler output temperature setting
•
Changing the DHW (hot water) or returning temperature setting
•
All alarms to be viewed in text format
•
Monitoring of the heating system operations
•
Monitoring of the operation of devices (fan, feeder, CH pump, DHW pump);
•
Monitoring of all temperature measurements
If the GA03HA room panel is correctly connected to the controller, it will be automatically
detected by the controller and does not require any additional steps or settings from the user.
SWITCHING ON THE ANTI-LEGIONELLA FUNCTION WILL
INCREASE THE TEMPERATURE OF DOMESTIC WATER TO 70C.
USE EXTREME CAUTION WHEN USING HOT WATER TO AVOID
SCALDING!!!
Proper communication between the panel and controller is shown by
the icon
on the controller panel, in negation in the system
operation preview screen
