Page 13: Using Cooling Functions
INSTRUCTIONS Using cooling functions If the installation is capable of doing cooling, a WLAC-1 switching module is installed. To enable cooling, switch the slider on the right hand side to the cooling position. The system now switches into cooling with a set point than is 3˚C above the master day set point. (In case the WLAC-1 module is connected to a BMS controlled signal, the BMS system will make the decision when to switch to cooling –... - Page 14 Additional information Master Settings Factory settings BA/FS Cooling mode Day cooling temperature Day heat temperature + 3°C Night cooling temperature Day cooling temperature + 3°C DEW point safety zone DEW point + 3°C Room temperature control PI - control P = 4°C I = 90-180 sec K-factor = 0.1 Floor Limit temperature control...

Page 15: Error Indication
The error number will be indicated by the number of fl ashes, with a pause of less than a 1/2 second between the fl ashes. The indication will be followed by a pause of 2 seconds, following which the sequence will be repeated. The failure code can also be seen in the service menu on WLM2-FS MASTERS (submenu 2). - Page 16 Flashing output LED (red): The appropriate output channel LED can fl ash, indicating that the room sensor or room contoller on that channel has a fault/error. The failure code can also be seen in the service menu (submenu 2a). E1, 1 fl ash The master has lost communication to the room sensor.
