D18 Co2 Value For Raising The Flow Rate - Viessmann VITOTRONIC 200 Service Instructions Manual

7D0F Min. supply air temperature for bypass
Vitovent 200-C:
■ Outdoor air temperature (heat exchanger air intake)
> "Min. supply air temperature for bypass 7D0F"
plus 0.5 K
Vitovent 300-F:
Supply air temperature > "Min. supply air tempera-
■
ture for bypass 7D0F" minus 1.5 K
and
■ Outdoor air temperature (heat exchanger air intake)
> "Min. supply air temperature for bypass 7D0F"
plus 1.5 K

7D18 CO2 value for raising the flow rate

Vitovent
200-C 200-W 300-C
— —
The air flow rate is increased if the CO
in the room exceeds the set limit. The air flow rate is
reduced if this limit is undershot.
The control limits are "Flow rate reduced ventilation
7D0A" and "Flow rate intensive ventilation 7D0C".
7D19 Humidity value for raising the flow rate
Vitovent
200-C 200-W 300-C
— —
The air flow rate is increased if the relative humidity in
the room exceeds the set limit. The air flow rate is
reduced if this limit is undershot.
The control limits are "Flow rate reduced ventilation
7D0A" and "Flow rate intensive ventilation 7D0C".
7D1A Fan blocking time with frost protection
Vitovent
200-C 200-W 300-C
— —
Only in conjunction with electric preheating coil ("Ena-
ble preheater bank electric 7D01" set to "1"):
If the supply air temperature falls below 5 °C, both
fans are switched off for the set duration. For reactiva-
tion, the supply air temperature must exceed 5 °C.
