CONDUCTOR W4
Cold draught protection
To prevent cold down-draughts, the controller can in certain cases switch on
both heating and cooling.
This is set via parameters: one parameter for setting the level of the output
signal for the hot water valve actuator and one parameter for how great the
cooling requirement can be before the heat is switched off.
Digital airflows
The function involves controller support for obtaining its airflow set point
from Modbus, both in the normal mode and in the BMS mode.
The set point is adjusted and the function is activated via parameters.
Digital Occupancy
The controller has support for activation of the occupancy mode via
Modbus, both in the normal mode and in the BMS mode. This function
interacts with the controller's internal occupancy switching and if any of
these signals are activated, the controller will switch over to the occupancy
mode. Occupancy is deactivated again when none of the signals is active
any longer.
Commissioning, Air/Water
The function can set the controller to a required commissioning mode
via Modbus, both in the normal mode and in the BMS mode. The
commissioning mode can also be selected from the Room unit. It is possible
to run an air sequence and a water sequence at the same time.
The various modes are the following:
Air
* Airflow, no occupants
* Airflow, minimum occupancy
* Airflow, maximum occupancy
* Airflow, Holiday
Water
* Open valve actuators, 100% cooling
* Open valve actuators, 100% heat
