Stand-by mode.
When the control system registers a signal indicating that a window is open,
the controller switches over to the standby mode. When the window is
closed, the controller switches to the AUTO operating mode.
While the controller is in the Stand-by mode, the room temperature is
maintained above the predefined level for the Frost protection function.
EMERG, emergency mode.
In the event of a fire alarm, the air damper in the extract air duct is opened
or closed, depending on the setting entered in the control system. The
cooling and heating functions are shut off while the system is in the EMERG
mode. The supply air is normally shut off.
The EMERG mode can only be managed in control systems that are
connected to a main control system via ModBus RTU.
There are a variety of functions built into the CONDUCTOR W1/W3:
• Exercising of valves
• First open
• Frost protection
• Change over
• Night cool
• Time-set setpoint restoration
Exercising of valves
The function involves regularly exercising the water valves by utilising
automated functions in order to prevent them from becoming sluggish or
jamming. During the exercising period, all the valves that are wired to the
controller are opened for a maximum of 6 minutes and are then closed.
The valves for the cooling system are exercised first. Then the valves for the
heating system are exercised.
First open
The function means that the water valves are open when the system is
installed, which makes it easier to fill, pressure test and vent the water
system.
The function will be automatically disabled after the actuator has been
energized for approx. 6 minutes. A clicking noise will be heard when the
valves and the dampers change over to the NC mode (=normally closed)
and the normal control function is enabled.
