Page 5: Unit Description
UNIT DESCRIPTION General The Daikin EKOMBG*AAV1 wall-mounted gas boiler is a closed unit. The unit is intended to provide heat to the water of a CH-installation and the domestic hot water installation. The air supply and the combustion gas outlet of the EKOMBG*AAV1 can be connected to the unit by two separate pipes, or by a concentric connection. - Page 6 This function keeps the heat exchanger at the right temperature (it can be set, see par. 7.2). The tap comfort function has the following settings: On: ( LED on) The tap comfort function of the unit is continuously switched on. • Daikin Europe NV...
