necessary for normal operation:
Display and setting of operating modes
Display of temperatures and setting of the room temperature set values
Display and programming of the weekly calendar
Display and handling of alarms
Password protection
Intended use also includes compliance with the operating instructions. Any usage
over and above this use is considered to be not as intended. The manufacturer

2.4 Operating modes
Code Operating mode
REMU RECU
REC Recirculation
On/Off recirculation operation with TempTronic algorithm: During heat or
cool demand, the unit draws in room air, heats or cools it and blows it back
into the room. The room temperature set value day is active. The flow rate is
controlled in 2 stages.
● ●
DES Destratication:
To avoid heat build-up under the ceiling, it may be appropriate to switch
on the fan when there is no heat or cool demand (either in permanent
operation or in on/off operation depending on air temperature under the
ceiling, as desired).
● ●
REC1 Recirculation speed 1
The same as REC, but the unit operates only at speed 1
(low air flow rate)
● ●
DES Destratication:
The same as for REC, but the unit operates only at speed 1
● ●
SA2 Supply air speed 2
The unit blows fresh air into the room. The fresh air ratio is adjustable.
Heating/cooling is controlled according to the heat/cool demand. The room
temperature set value day is active. The unit operates at speed 2 (high air
flow rate).
●
SA1 Supply air speed 1
The same as SA2, but the unit operates at speed 1 (low air flow rate)
●
ST Standby
The unit is normally switched off. The following functions remain active:
● ●
CPR Cooling protection:
If the room temperature drops below the set value for cooling protection,
the unit heats up the room in recirculation operation.
● ●
OPR Overheating protection:
If the room temperature rises above the set value for overheating
protection, the unit cools down the room in recirculation operation. If
the temperatures also permit fresh air cooling, the units automatically
switches to night cooling (NCS) to save energy.
● ●
NCS Night cooling:
If the room temperature exceeds the set value for night cooling and the
current fresh air temperature permits it, the unit blows cool fresh air into
the room and extracts warmer room air.
●
L_OFF Off (local operating mode)
The unit is switched off. Frost protection remains active.
● ●
–Forced heating
The unit draws in room air, warms it and blows it back into the room. For
example, forced heating is suitable for heating the hall before taking the
control system into operation or if the controller fails during the heating
period.
Forced heating can be activated and set as required by the Hoval service
technician.
●
Forced heating is activated by connecting the unit to a power supply (only
if there is no bus connection to the zone controller).
●
