3.4.8. PARAMETERS
PRE-HEATING
Temperature
– current readout from sensor dedicated for
pre-heating coil
Setpoint
– current setpoint for the regulator, read only
Heating rate
– indicates current heating capacity
0% – no heating, 100% – full heating
Pump status
– indicates current state of the circulation
pump
Alarm status
– indicate the state of frost protection input
Note!
The pre-heating coil works out of the standard
cooling/heating sequence. It is intended just to keep the
constant temperature in specified place, e.g. to heat up
outside air before entering the heat recovery unit.

EXH MOTORS
Freq
- actual output frequency
Current
- actual current consumption
Status
- combined information for communication problems
and for motor alarms
OK
- no malfunctions
Comm
- communication to the frequency converter not
stable or lost
Alarm
- communication OK, but frequency converter
reported an error, e.g. overload
Note!
Ventus AHU can have up to 4 frequency converters
in one fan set (MultiFan configuration). All FCs in the
fan set have common settings for frequency, ramp-up,
ramp-down and the main limits – as they must work
synchronously.
Note!
FC details visible only if frequency converters were
enabled during unit configuration
