Central apartment unit for HVAC and energy consumption data collection
The central apartment unit serves as an operator and display unit for an apartment.
It manages individual room control (heating/cooling) of up to 12 rooms, comfort ventilation, precontrol, control of air conditioning equipment, and acquires the consumption data of heat, water, electricity and gas.
• Management of heating and cooling control for one apartment
• Suited for heating and cooling plants with central distribution (e.g. underfloor heating) and radiators with decentral connections
• Selection of operating mode, timer and holidays / special day function for the apartment • Independent time switches and operating modes for 12 rooms
• Flow temperature control of 2 independent room groups including limitation (min. / max.) and maintained return temperature (high / low)
• Increase of economy room temperature setpoint and minimum flow temperature setpoint depending on the composite outside temperature
• Collection of heat / cooling requests from the individual rooms and forwarding the requests to the heat/cooling sources via wired bus, heat/cooling demand relay or DC 0...10 V output to the RRV912 or RRV934
• Absence function (heating, cooling, ventilation)
• Management of 3-stage ventilation plant via RRV934 multicontroller, incl. night cooling
• Control of air conditioners (split units) via universal outputs (locally and RRV91x) or via S-Mode (KNX TP1)
• Display of meteorological data
• Presentation of key data on info pages
• Remote access via Siemens web server OZW772.xx
• Collection of meter data (heat / cool, electricity, water, gas) to support automated meter reading & billing
