Description
EG4 - Humidity regulation frequency
Setting of desired frequency for how often the fan speed
may be changed.
The function is defined as 1% per unit of time.
When humidity regulation is activated, the current
humidity is continuously measured via the integrated
humidity sensor in the ventilation unit, which is placed
in the extract air duct.
EH1 - Rotor speed (rpm)
setpoint value for minimum rotary heatexchanger speed (rounds
per minute)
Be aware that a reduction in RPM might decrease heat recovery
rate but will increase the operating range of humidity recovery.
This values should be adjusted by an installer.
EH2 - Rotor stop C
Offset temperature setpoint for stop of heatrecovery using a
rotary heatexchanger.
for example
setpoint temperatur 20 °C
EH2 = 2
Rotary heatexchanger will stop when fresh air temperatur T3 is
20-2= 18 °C
This function will save energy for the rotor motor when there is
limited possibility to recover energy
EH3 - Rotor max deicing time
Setpoint in minutes for maximum time used for decicing rotary
heatexchanger. When exceeding the time limit the rotary
heatexchanger will return to normal operation.
EH4 - Rotor deicing pause
Setpoint in hours corresponding to minimum time between deicing
cycles
EI1 - CO 2 control
On = activates external sensors for demand control (if available)
Off = no external sensors for demand control available
EI2 - CO 2 setpoint
setpoint for desired CO 2 level in PPM.
If CO 2 level increase above setpoint, the fans will increase speed
in steps to maintain CO 2 level at setpoint.
EI3 - CO 2 level time
setpoint in minutes for time between increase/decrease fanspeed
in steps according to CO 2 level (see setpoint EI2)
EI4 - Number of RF CO 2 sensors
Select number of wireless CO 2 sensors connected.
Make sure that the dip switches in the CO 2 sensors are set correct
according to seperate documentation.
