EC - Regulator

Description
6 The relay will be on when terminal L1 is bridged (for example
by connecting an kitchen hood to the MVHR unit). This function
can be used to activate a damper which will reduce airflow to
the rest of the house and focus extraction through the kitchen
hood.
EC6 - Regulation water
If a water reheater with a motor-operated valve is installed in the
system, it may be necessary to adjust the regulation time. The less
regulation time, the faster the motor-operated valve will regulate.
EC7 - Water heat protection
If a water reheater with motor-operated valve is installed in the
system, a frost protection sensor must be fitted to the water
reheater and the set point must be set to ON.
If no frost protection sensor is installed, the set point must be set
to OFF.
EC8 - Water heat protection temperature
If frost protection in item 25 is set to ON, the frost protection
temperature must be set to the temperature where the system
should stop and the motor-operated valve open completely for
the flow of hot water.
EC9 - System stop
Here you choose if it should be possible to stop the system by
selecting "standby" in fanspeed settings. If the set point is OFF,
the system cannot be turned off.
If On is chosen then "standby" will be shown in fanspeed selector
on main screen.
EC10 - Right / left model
right = MVHR configured as a right version (only applicable for
counterflow heatexchanger units and rotor right version)
left = MVHR configured as a left model (only applicable for
counterflow heatexchanger units)
rotor left = MVHR configured as a left model (only applicable for
rotary heatexchanger units)
Note this setting should only be changed by the installer as there
is a risk of corruption of the machine functions if wrong setting is
applied.
EC11 - Factory reset
Factory reset (-fans) = reset all controller values to factory
settings except fanspeeds
Factory reset = reset all controller values to factory settings
