Cooler control mode.
Two options are available:
manual (on)
and
auto
. If discrete is selected, the cooler can be switched on manually
or automatically. If analogue is selected, the 0...100 % cooler control slider appears on selecting the manual mode.
Min. time before OFF.
The minimum time for the cooler operation before deactivation.
Min. time before ON.
The minimum time for the cooler idling before re-activation.
Cooler hysteresis.
Available for coolers with discrete control.
Bypass/rotary heat exchanger control mode.
Displays the bypass control mode or the rotary heat exchanger control mode depending
on the unit configuration. The following modes are available for discrete configurations of the bypass/rotary heat exchanger:
close/run,
open/stop, auto.
The following modes are available for analogue configurations of the bypass/rotary heat exchanger:
manual
and
auto
.
If manual mode is enabled, the
0...100 %
bypass/rotary heat exchanger control slider appears. The 0 % value corresponds to a completely
closed position of the bypass or maximum speed of the rotary heat exchanger.
Freeze protection.
Types of heat exchanger freeze protection.
Freeze protection is activated if the outdoor temperature drops below -3 °С and the supply and extract fans are enabled. Freeze protection
is deactivated when the outdoor temperature raises above -1 °С or if the supply or extract fan is disabled.
Protection by supply fan
The fan speed is smoothly changed to maintain the temperature of +5 °С in the exhaust duct downstream of the heat exchanger.
Protection by bypass
The protection is activated if the bypass is set to automatic and the air temperature in the exhaust duct downstream of the heat
exchanger drops below +5 °С (+3 °С for a two-point bypass). Protection is deactivated if the bypass is opened/closed manually or if the
air temperature in the exhaust air duct downstream of the heat exchanger raises above +7 °С (+6 °С for a two-point bypass). The bypass
maintains the temperature of +5 °С in the exhaust duct downstream of the heat exchanger.
Note:
the freeze protection operates only if the main heater is enabled, the bypass is installed on the outdoor side and
Heating
or
Auto
mode is selected.
Protection by electric preheater
If freeze protection is activated, the preheater maintains the temperature of +5 °С in the exhaust duct downstream of the heat exchanger.
Note:
deactivate freeze protection at your own risk. This information is also provided in the corresponding on-screen warning.
While selecting protection by preheater make sure that the preheater is connected to the unit to avoid triggering an alarm condition and
causing the unit to shut down.
