Description
Thermostat runs sequences depending on the
water temperature
Heating / cooling controlled manually by user
(via HMI)
Temperature measurement using external
sensors
Switch operating mode locally or via bus
Switch operating mode locally or via bus
To ensure correct acquisition of the water
temperature
and reduce wear and tear
To optimize use of heating/cooling energy in
mixed systems
Application without fan control
Control external equipment based on function
state (heating/cooling demand, operating mode,
sequence, humidity, ...)
For user Comfort and floor protection
To save energy, by avoiding room air that is too
hot or cold
To balance heating and cooling and avoid
hydraulic issues due to different flow rates
To prevent condensation damage in the building ✓
To prevent valve freezing after extended
inactivity
To limit access by unauthorized persons
Indication on energy efficiency
Limit min. and max. humidity in the room
To ensure setpoint temperature is reached
during heating
NFC communication via Siemens smartphone
