Room thermostats, ceiling heating and cooling, air conditioning and fan coils, roller shutters and safety sensors – coordinated by a single controller pair in the apartment's distribution board, even without internet.
Ceiling heating and cooling control
Radiant ceiling emitters are controlled room by room: weather-compensated, even warmth in winter, and dew-point-based quiet cooling in summer, without fan noise.
Plant room–apartment sync
Room-by-room control
Precise zone control
Air-conditioning control
Apartment AC units join the system over Wi-Fi through the SINUM AC Gateway: more than ten brands, mode, fan speed and setpoint from one interface, coordinated with ceiling cooling.
Coordinated with ceiling cooling
Control by the room thermostat
Mode and fan speed
Fan-coil control
Fan coils are controlled via Modbus, 230 V speed switching or stepless 0–10 V according to room demand, coordinated with the valve control.
Full sync with the thermostat
With emitter staging
Can be automated
Dew point protection
The system continuously calculates the dew point from room temperature and humidity and keeps the cooling supply temperature above it with a safety margin, so no condensation forms on the ceiling.
Real-time dew point calculation
Gradual cooling limitation
Alarms and logging
Roller shutter control
Roller shutters calibrate automatically, so positions are accurate to the percent. They move with scenes and schedules, and reduce cooling demand in summer.
Unified control of multiple shutters
Open, half-shade, closed
Automatic calibration
Smoke and water leak detection
Wireless sensors monitor the apartment. In case of smoke or a leak they sound a local alarm and notify both the resident and the building operator.

AI-based zone control
Measured data is turned into a comfort index, and zone control is coordinated. The system recognises, for example, air that is too dry or too humid.

Valve and pump control
The KW-15m's 0–10 V output modulates the mixing valve continuously with built-in PID control. Its 9 relay outputs switch the room-circuit actuators and the 230 V pump.

Pipe burst and leak protection
The CZ-01 water leak sensor reacts to the very first drops: the resident and the operator are notified at once, so a leak can be stopped before it reaches the apartment below.

Resident app · iOS and Android
The apartment and the building in your pocket
Residents use the native Sinum CONNECT app to control their apartment, see their consumption and receive the building's notifications – even under the project's own brand.
Dashboard: the apartment at a glance
The home screen shows the apartment's average temperature and humidity, the state of each room, the local weather and the comfort score, together with the next heating programme.

Thermostats and target temperature
Measured and set temperature and humidity for every room in one list. A shared target can be applied to all zones in one move, and heating programmes can be scheduled.

Shutters and scenes
Roller shutters move room by room or all together, to the exact percentage. Morning, evening and away scenes coordinate heating, lighting and shading with a single tap.

Consumption and statistics
Residents see their monthly heating, cooling, cold and hot water consumption compared with the previous period. A daily chart helps spot unusual use.

Plant room and heating plant · BMS supervision
The plant room, live with measured data
A dedicated Sinum PRO hub supervises the heating plant. Heat pumps, buffers, DHW, mixing circuits and meters appear on a single interface, and the apartments' heat demand goes straight to the heat generators.
BMS supervision
A live schematic shows every circuit, pump and temperature in the plant room. Deviations trigger alarms, and every event is logged.
Plant room templates

Alarms and log
Heat generators
Heat pumps, buffer tanks and DHW cylinders can be tracked in real time, and efficiency is measured, not estimated: heat output and COP.

Mixing circuits
Flow temperature is controlled circuit by circuit, based on the actual demand of the apartments. Flow is shown as a solid line, return as a dashed line.

Heat metering
The apartment's heat meter is read directly via the M-Bus input. Two NTC sensors measure the mixing circuit temperature.
