10.6.2 Analogue Inputs
The analogue inputs show the temperatures of the various sensors as well as the operating signal / mutual fan monitoring.
Analogue inputs Temperature
AE1 Outdoor temperature 7.1 °C
AE2 Supply air temperature 23.4 °C
AE4 Extract air temperature 22.0 °C
UAE1 Hot water temperature 44.6 °C
UAE2 Supply air fan monitoring 10 V
UAE3 Extract air fan monitoring 10 V
UAE4 Secondary air fan monitoring 10 V
UA 2 ... 4 Relevant for the fan monitoring (see "8.1.4 Conrm Faults / Procedure" page 57).
10 V: failure-free operation
0 V: triggers an alarm
10.6.3 Digital Inputs
Digital inputs show operating signals.
Digital inputs
DE1 EVU status On
DE2 Pressure monitoring alarm Off
DE3 PV Off
DE4 Rotor operation Off
DE1 EVU Set to Off, as long as the forced shutdown of the utility company is active. see “Ser-
vice manual/Wiring Diagram”.
DE2 Pressure monitoring If there is a replace and pressure monitoring (provided on-site by the client) is
required, it is connected here. see “Service manual/Wiring Diagram”.
WARNING
Scalding
Risk of scalds with water temperatures higher than 43 °C.
» The client must provide protection against scalding!
DE3 PV If this input receives a signal from an inverter of a photovoltaic system, the hot water
will be heated to a temperature of 60°C using an electric heating rod.
DE4, rotor operation On/Off Changes during rotor operation steadily from Off to On. This is not an error, but is
caused by the rotor monitoring.
