The temperature sensor for the hot water flow is defective. • Flashing RED (3x every 4 seconds): The temperature sensor for the hot water return is defective. • Flashing RED (4x every 4 seconds): The potentiometer for manual setting of the hot water temperature is defective. www.eta.co.at... - Page 9 Description Function The cold water that simultaneously flows through the the plate heat exchanger and mixes this with the hot plate heat exchanger on the secondary side absorbs heating water from the buffer. As a result of this, the this heat and exits the fresh water module as hot water. critical calcification temperature of 60°C is not reached and lime buildup is prevented.

Page 10: Information For Installation
At 0.15 m³/h feed capacity, an installation with a new aluminium interconnector (16 x 2.2 mm, 20 m length, 6 fittings) has a line resistance of approx. 0.65 mWs. This roughly corresponds to the transport height of the circulation pump and thus fits. www.eta.co.at... -

In this case the pipework set can be left out. For installation on the buffer, an optional pipework set is available from ETA. The room height must be at least the buffer height plus 100 mm for the installation of the pipework and the ventilation valve. - Page 12 Mount the 4 screws in the wall, hang the fresh water module on these and fasten in place.
