Radiator thermostat, Basic Radiator thermostat, Comfort
Fig. 1: 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®app.
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.

Made available by: Radiator thermostat Basic / Comfort
Function: Regulates free@home radiator
thermostats (actuating drives)
Table 3: Overview of functions
Basic functions of Basic
The Basic version of the device has two push-buttons on top of the device:
■OFF (off button): Switches the device into the OFF mode. This means that the temperature
is no longer regulated. The frost protection function and valve protection function are active.
■Comfort: Switches the device into Comfort mode. The temperature is regulated to the
setpoint value. The setpoint value can be set via a connected extension unit (e.g. a
free@home-Touch 7“ or a free@home room temperature controller) or via the ABB-
free@home®app.
Basic functions of Comfort
The Comfort version has two push-buttons on top of the device, as well as a rotary knob at the
front of the device:
■ON/OFF (off button): Switches the device into the OFF mode or Comfort mode. The
temperature is not regulated in the OFF mode. The frost protection function and valve
protection function are active. In Comfort mode the temperature is regulated to the setpoint
value. The setpoint value can be set locally via the rotary control element. The setpoint
value can also be set via a connected extension unit (e.g. a free@home-Touch 7“ or a
free@home room temperature controller) or via the ABB-free@home®app.
■ECO: This is used to switch over between Comfort and ECO mode. In ECO mode the
temperature is reduced by a pre-programmed value. Example: You are leaving the room for
a few hours; the room temperature is to be reduced to save energy; however, the room is
not to cool down completely.

Additional functions of both device versions
■Extension unit mode: The radiator thermostat can be linked with other free@home
devices, so that these can then be used as "Extension unit" to remote control the heating
mode and the setpoint value of the radiator thermostat.
The temperature measurement and regulation continues to be carried out in this mode
locally in the radiator thermostat.
Devices that can be linked as extension unit with a radiator thermostat:
– free@home-Touch 7“
– free@home-Touch 4.3“
– Room temperature controller
– Wireless room temperature controller
– ABB-free@home®app
■Low battery warning: The user is informed when the power of the battery drops below a
critical level. Although the radiator thermostat will continue to function for a few days after
the warning, replacement batteries should be kept ready. When the battery is completely
flat, the radiator thermostat remains in the position set last!
■Valve protection function: To protect the valve, the radiator thermostat carries out a valve
protection movement every two weeks. The valve is moved to the fully open and closed
position once.
■Valve adaptation: The adaptation movement is carried out during commissioning of the
radiator thermostat. This determines whether the valve can be actuated and the size of the
stroke for calibrating the radiator thermostat to this valve. A defective or non-existing valve
leads to an error message.
In case of a defective valve, please contact the installer of your heating system to replace
the valve.
■Window open detection: The radiator thermostat can be linked with a window contact in
the free@home configuration interface. When the window is opened, the radiator thermostat
is switched off automatically or switched back on again when the window is closed.

5 Connection and installation
Note
Transmitter and receiver communicate via radio control. The transmission range
depends on the structural conditions. Walls and ceilings, especially steel
reinforcements or metal claddings, reduce the transmission range. The distance
of components to other transmitters that also emit high-frequency signals (e.g.
computers, audio and video systems) should be at least 1 m.
Radio range
To minimize the consumption of power, battery-operated free@home wireless devices are not
operated as repeaters. Different to free@home wireless devices with mains power, a received
command is therefore not transferred.
That is why during the installation it should ensured that there is at least one free@home
wireless device with mains power supply within the range of the battery-operated device.
Planning instructions
Planning and application instructions for the system are available in the ABB-free@home®
system manual. This can be downloaded at www.abb.com/freeathome.
5.1 Installation
Mounting and installation are identical for both device versions. In the following, only the
Comfort version is shown as an example.
If the device is not in factory settings, the batteries must first be inserted, (See “Inserting the

6 Commissioning
Commissioning of the device is always carried out via the Web-based surface of the System
Access Point. It is assumed that the basic commissioning steps of the overall system have
already been carried out. Knowledge about the Web-based commissioning software of the
System Access Point is assumed.
The System Access Point establishes the connection between the free@home participants and
the smartphone, tablet or PC. The System Access Point is used to identify and program the
participants during commissioning.
When energized, Basic and Comfort thermostats that have not been programmed are in
programming mode for 10 minutes and can be logged into the system. Programmed devices
share information about their type and supported functions with the System Access Point.
During initial commissioning all devices are given a universal name. The installer must change
this name within the commissioning process to a name practical and specific for the system.
The devices must be parameterised for the use of additional functions.
Note
General information about commissioning and parameterization is available in
the ABB-free@home®system manual.
6.1 Coupling of wireless devices with the System Access Point
6.1.1 Coupling devices
free@home wireless devices must first be coupled with the System Access Point before they
can be used in a project. The devices exchange a security key during the coupling process.
Communication between devices is carried out encrypted after coupling and they are firmly
connected with the System Access Point. Coupled devices cannot be connected with a different
System Access Point. They must first be reset to the factory settings.
Note
Separate commissioning is carried out for thermostats.
Carry out the following steps to couple one or several devices with the system:
1. Install the free@home wireless device(s).
2. Use your smartphone, tablet or PC to call up the user interface of the System Access Point
that is ready for use.
3. Remove the batteries from the device.
4. Start the scanning mode ("Settings" > "free@home-Wireless" > "Search for wireless
