Product overview of Radiator thermostats (Basic and Comfort)
The radiator thermostats HA-S-1-WL and HA-S-2-WL can be used to create a convenient single
room control of the temperature by operating the radiator heating (water-bearing radiators)
guided via wireless signal. No laying of cables required. Communication with the free@home
system is carried out wireless.
The radiator thermostats have an integrated temperature sensor, an integrated temperature
control, as well as an electric motor with drive unit to move the heating valve to a desired
position.
Other than the System Access Point, the devices require no further accessories for
commissioning.
The measured actual temperature value of the radiator thermostats is not displayed in the
visualization of the ABB-free@home
The devices are not pre-programmed. Programming is carried out via the user interface of the
System Access Point.
Battery service life
The service life of the battery depends mainly on the respective usage. This means on how
often the motor of the actuating drive is moved, on the battery type and its state of charge.
Standard usage (in actuating drive status: 2 setpoint adjustments per day; in OFF mode from
May to September) the service life of the battery lasts generally up to 2 years.
Noise impairment
An electric motor operates inside the actuating drive. It influences the position of the valve
tappet via a drive unit. Fundamentally there is a low noise impairment when the motor moves to
a new valve position.
A new valve position is moved to when the user manually specifies a new setpoint value or a
time program. Also to regulate and to maintain a constant temperature an opening and closing
of the valve is necessary.
Movements of the motor are kept to a minimum to save power.
