Operation
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-

pass conditions).
The operation of the bypass valve can be adjusted in step num-
ber 5, 6 and step number 7 in the settings menu (see chapter
13).
4.3 Frost protection
To prevent freezing of the heat exchanger at extremely low out-
door temperatures, the Renovent Excellent features intelligent
frost control. Temperature sensors measure the temperatures
across the heat exchanger and, if necessary, the preheater is
switched on. That guarantees a proper ventilation balance,
also at very low outdoor temperatures.
Bypass valve conditions
Bypass valve open
- The outdoor temperature is higher than 10°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. 5 in the set-
tings menu (set standard at 22°C).
Bypass valve closed
- The outdoor temperature is lower than 10°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. 5 in the
settings menu minus the set temperature on the hysteresis (step no 6), this temperature is
standerd set at 20 ° C (22.0 ° C minus 2.0 ° C).

The Renovent Excellent is also available as Plus version. This
version is equipped with a different control board with 2 additio-
nal connectors (X14 & X15) with more connection options for
various applications.
The 9-pole connector X15 is accessible at the rear of the Re-
novent Excellent display cover without having to open the ap-
pliance.
The 2-pole connector X14 is accessible after taking off the

second gland. That makes it possible to feed a 230 volt cable,
which may be connected to connector X14, two outside the
appliance.
See § 11.1 for more information on the connection possibilities
of connectors X14 and X15.
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.
