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
