• Management of heating control for one apartment
• Increase of Economy room setpoint and of the minimum flow temperature set-
point as a function of the composite outside temperature
• Collection of heat requests from the individual rooms
• Generation of heat request signal and transmission to heat generation via wired
bus, heat demand relay, or DC 0...10 V output to the RRV912 or RRV934 heat-
ing circuit controller
• Suited for heating plant with central heat distribution (e.g. floor heating) and ra-
diators with decentralized connections
• Control of heating circuits with RRV912 / RRV918 heating circuit controllers and
SSA955 radiator control actuators
• Flow temperature control of 2 independent room groups with limitation function
(minimum / maximum)
• Maintained return temperature (high / low)
• Control of room group pumps via universal relay outputs
• Control of DHW pump / diverting valve via universal relay output. Acquisition of
DHW temperature via universal input
• Management of ventilation plant via RRV934 multi-controller
• Night cooling function (bypass function of HR)
• Control of air conditioners (split units) via the universal outputs (locally and
RRV91x) or S-Mode (KNX TP1)
• Release of cooling enable contacts per room depending on the composite out-
side temperature, the current HVAC level, the state of the windows, and a heat
request
• Monitoring of door contacts, window contacts and smoke detectors
• Operation of lights and blinds via softkeys, time switch and events
• Simulation of presence through random switching of lights combined with per-
manent ON of one or several light sources
• Generation, storage and retrieval of scenes
• Display of progression of outside temperature and atmospheric pressure over
the last 24 hours with the help of the QAC910 meteo sensor
• Display of open doors and windows
• Display of weather trend (sunny, cloudy, rainy)
• Remote access via Siemens OZW77x central communication units
The central apartment unit can be used in connection with the following RF prod-
ucts of the Siemens Synco living system and those of other suppliers of wireless
KNX products:
