- Page 11 Network variables 7.2 Write access With write access, set values can be specified or adjusted in the control unit, subject to operating mode, via a LON-Works network. For safety reasons, all variables that are available for BMS write access are monitored regarding their min./max. limits. If a value outside the valid value range is sent, the value is rejected and the original value is retained.
- Page 12 7. Network variables If a LON interface module is installed, the system can be operated in 3 different 7.2.2 Operating mode operating modes: Manual mode 7-day program BMS mode Manual mode The system runs with the set values specified for manual mode via the BMK programming module.
- Page 13 The set values for speed or pressure can be adjusted via the remote control in 3 stages (see WRS-K installation and operating instructions). Here, the set value is altered according to the values specified in the standard settings for supply air and extract air.
- Page 14 7. Network variables In BMS mode, all set values are specified via the LON interface. The system is also 7.2.4 BMS mode switched on and off via the LON interface. The following variables are effective: nviTempSet (set temperature) nviSpSupSet (set speed for supply air fan) nviSpExhSet (set speed for extract air fan) nviFrAirSet (set value for fresh air proportion) nviPresSupSet (set pressure for supply air)
