NOTE
This menu shows whether the digital inputs of the control-
ler are switched on or o.
Defr/Brin/Flow Defrost, Brine pressure, ow
Depending on the device type, the
input can full various functions:
For L/W-devices
Defrost end pressostat:
On = Defrost is terminated.
For LWD, LWP, S/W and W/W devices with ow
switch connected at the factory:
On = Flow okay.
For S/W-devices without ow switch
connected at the factory, a brine
pressostat can be connected:
On = brine pressure sucient.
SW-therm. switch Domestic hot water thermostat
On = Domestic hot water requirement
Energy supply company O-time of the electrical supplier
O = O-time
High pressure High-pressure pressostat
O = Pressure okay
Motor protect. Motor protection
On = Motor protection okay.
Low pressure Low pressure pressostat
On = Pressure okay.
potent. ext. Connection of an external current
anode (possible for some devices)
Analog In … Analogue input signal (e.g. for ow
sensor)
release cooling ON = cooling enabled (from external)
present
High pressure High-pressure sensor
Low pressure Low-pressure sensor
ow Heating circuit ow rate
