4.2 Bypass conditions
The standard bypass valve makes it possible to supply fresh
outside air that is not heated by the heat exchanger. Particular-
ly during summer nights it is desirable to supply cooler outside
air. Then the hot air in the dwelling is replaced by cooler outside
air in so far as possible. The bypass valve opens and closes automatically when a num-

Bypass valve conditions
Bypass valve open
- The outdoor temperature is higher than 7°C and
- the outdoor temperature is lower than the indoor temperature in the dwelling and
- the temperature in the dwelling is higher than the temperature set at step no. 9 in the set-
tings menu (set standard at 22°C).
Bypass valve closed
- The outdoor temperature is lower than 7°C or
- the outdoor temperature is higher than de indoor temperature in the dwelling or
- the temperature outside the dwelling is lower than the temperature set at step no. 9 in the
settings menu minus the set temperature on the hysteresis (step no 10), this temperature is
standerd set at 20 °C (22.0 °C minus 2.0 °C).
4.1 Description
The appliance comes plug and play and operates fully auto-
matically. The extracted indoor air heats up the fresh, clean
outdoor air. That saves energy and fresh air is sent to the re-
quired rooms. 7KHFRQWUROV\VWHPKDVWKUHHYHQWLODWLRQPRGHV7KHDLUÀRZ

4.3 Frost protection
To prevent freezing of the heat exchanger at extremely low
outdoor temperatures, the Renovent Excellent P300 features
intelligent frost control. Temperature sensors measure the tem-
peratures across the heat exchanger and, if necessary, when
the changer is threatening to freeze, there is a stepless imbal-
ance in the appliance. That guarantees a proper ventilation balance, also at very low
outdoor temperatures.
When the preheater (option) is switched on and at extremely
low outside temperatures the changer is still threatening to
freeze, it will cause a stepless unbalance in the appliance.
