Homematic IP HmIP-WTH-B Wireless Wall Thermostat 13

Mount wall thermostat in a flush-mounted box

Function

This device is part of the Homematic IP smart home system and works with the Homematic IP radio protocol. All devices of the Homematic IP system can be conﬁgured comfortably and individually with a smartphone via the Homematic IP app. Alternatively, you have the option of operating Homematic IP devices via the CCU2/CCU3 or in conjunction with many partner solutions. The available functions provided by the system in combination with other components are described in the Homematic IP User Guide.
The Homematic IP Wall Thermostat enables time-controlled regulation of your conventional radiators with Homematic IP radiator thermostats or, in combination with Homematic IP ﬂoor heating actuators, of your ﬂoor heating, and adjusts heating phases to your individual needs.
The wall thermostat measures room temperature and humidity and transmits these at intervals to the radiator thermostats or ﬂoor heating actuators enabling room temperatures to be precisely controlled. In combination with a Homematic IP Window and Door Contact, the temperature is automatically reduced during ventilation.
You can get the wall thermostat to teach-in one or more Homematic IP devices (e.g. the Homematic IP Radiator Thermostat – basic) and conﬁgure it to your personal requirements. Alternatively, you can comfortably control the wall thermostat in combination with a Homematic IP Access Point via the free smartphone app.
Thanks to battery operation and radio communication, the wall thermostat is highly ﬂexible concerning the mounting location.
All current technical documents and updates are provided at www.homematic- ip.com.
When selecting the installation location, check for electrical wires and power supply cables.
Notes for mounting on a flush-mounted box

If the device is mounted to a ﬂush-mounting box, there may be no open conductor ends.
If changes or works have to be made on the house installation (e.g. extension, bypass of switch- or socket inserts) or the low-voltage distribution for mounting or installing the device, the following safety instruction must be considered:
Please note! Only to be installed by persons with the relevant electro-technical knowledge and experience!*

Incorrect installation can put your own life at risk and the lives of other users of the electrical system. Incorrect installation also means that you are running the risk of serious damage to property, e.g. because of a ﬁre. You may be personally liable in the event of injuries or damage to property. Contact an electrical installer!
Specialist knowledge required for installation: The following specialist knowledge is particularly important during installation:

The “5 safety rules” to be used:
Disconnect from mains; Safeguard from switching on again; Check that system is deenergised; Earth and short circuit; Cover or cordon off neighbouring live parts;
Select suitable tool, measuring equipment and, if necessary, personal safety equipment;
Evaluation of measuring results;
Selection of electrical installation material for safeguarding shut-off conditions;
IP protection types;
Installation of electrical installation material;
Type of supply network (TN system, IT system, TT system) and the resulting connecting conditions (classical zero balancing, protective earthing, required additional measures etc.).
