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.
The control system has four ventilation modes.
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.
Bypass - The outdoor temperature is higher than 7°C and
valve - the outdoor temperature is lower than the indoor temperature in the dwelling and
open - the temperature in the dwelling is higher than the temperature set at step no. 5 in the settings menu
(set a standard at 24°C).
Bypass - The outdoor temperature is lower than 7°C or
valve - the outdoor temperature is higher than de indoor temperature in the dwelling or
closed - the temperature from the dwelling is lower than the temperature set at step no. 5 in the settings menu minus the
set temperature by the hysteresis (step no. 6), this temperature is factory 22 °C (24,0 °C minus 2,0 °C).

Frost protection

To prevent freezing of the heat exchanger at extremely low out-
door temperatures, the appliance features intelligent frost con-
trol. Temperature sensors measure the temperatures across
the heat exchanger and, if necessary, the optional -preheater
is switched on. That guarantees a proper ventilation balance,
also at very low outdoor temperatures. If, with switched on
4.4 Renovent Sky EnthalpPlus version
The Renovent Sky 300 Enthalpy is also available as Plus ver-
sion. This version is equipped with a different control board with
2 additional connectors (X14 & X15) with more connection op-
tions for various applications.
Only the Plus is equipped with a 9-pole connector (connected
to X15 on control board) that is accessible from the outside of
the appliance.
If a postheater or extra preheater is connected to connector
X14 (accessible after opening the front panel) the installer must
feed the connected 230 Volt cable to outside the appliance
through a strain reliever. For this strain reliever (not supplied
with the appliance) a plug must be removed from the position
where this strain relieve must be placed.
See §9 for more information on the connection possibilities of
connectors X14 and X15.

Operation

The air flow rate can be adjusted per ventilation mode. The
constant volume control system ensures that the air flow rate
of the supply and extract fans is realised independent of the
duct pressure.
The bypass valve opens and closes automatically when a num-
ber of conditions are satisfied (refer to the table below for by-
pass conditions).
The operation of the bypass valve can be adjusted in step num-
ber 5, step number 6 and step number 7 in the settings menu
(see chapter 12).
