Finder 1C.B1.9.005.0007 – 1C Series BLISS – BLISS2 Smart Thermostat

Why Choose the Finder 1C.B1.9.005.0007 BLISS2 Smart Thermostat?

The Finder 1C.B1.9.005.0007 BLISS2 Smart Thermostat is an advanced electronic room thermostat designed for intelligent heating and temperature control in domestic and compatible light-commercial installations. Part of the Finder Series 1C, BLISS2 combines accurate room temperature regulation, programmable heating schedules, humidity monitoring and smart-home connectivity in a stylish, easy-to-use device.

Designed to bring greater convenience and flexibility to central heating management, the Finder BLISS2 thermostat allows users to adjust room temperatures directly from its illuminated LED matrix display or remotely through the Finder YOU app when connected to a compatible gateway. Integration with Amazon Alexa and Google Assistant also enables supported voice commands, making everyday heating adjustments quicker and more convenient.

The thermostat operates using three AAA batteries, with an estimated battery life of approximately 18 months under typical operating conditions. An optional external power supply is also available, providing installation flexibility when upgrading an existing room thermostat or designing a new heating-control system.

For connected operation, BLISS2 communicates using 868 MHz radio frequency technology with the second-generation Finder 1Y.GU.005.1 YESLY Gateway. The gateway connects to a 2.4 GHz Wi-Fi network, enabling remote temperature adjustments, weekly programming and supported smart-home voice control.

Important: Product reference 1C.B1.9.005.0007 is the standalone BLISS2 thermostat. The gateway is supplied separately and is required for remote app control and voice assistant integration. The thermostat can also operate locally without a gateway.

Intelligent Temperature Management for Comfortable Indoor Environments

Maintaining a comfortable indoor environment requires an effective balance between room temperature, heating schedules and energy consumption. The Finder 1C.B1.9.005.0007 BLISS2 Smart Thermostat provides electronic temperature regulation, allowing a compatible heating or cooling system to respond to changing room conditions and user-selected settings.

With an adjustable temperature range of 5°C to 37°C and a resolution of 0.1°C, the thermostat provides convenient control over the desired indoor temperature. Its integrated sensor monitors ambient room conditions, while the illuminated LED matrix display enables users to view information and make adjustments directly from the device.

When connected to a compatible Finder gateway, the BLISS2 thermostat can be managed using the Finder YOU application. Users can establish weekly heating schedules, change target temperatures remotely and organise different comfort settings to suit their daily routines.

For example, a household can schedule a comfortable temperature during the morning, reduce heating demand while the property is unoccupied and restore the preferred temperature before occupants return home. At night, a lower programmed temperature may help avoid unnecessary heating operation.

The thermostat also supports timed manual temperature overrides. A user can temporarily select a different target temperature for a set number of hours, from 1 hour upwards. When the selected period finishes, the thermostat returns to its automatic weekly programme. Permanent manual operation is also available where a fixed temperature is preferred.

An integrated relative humidity sensor allows users to view the humidity conditions within the room. This additional environmental information can be useful when monitoring indoor comfort alongside room temperature.

The thermostat's battery-operated design provides installation flexibility, particularly when replacing conventional wall-mounted controllers. For fixed-power installations, Finder also offers an optional external supply. When this supply is used, the thermostat batteries must be removed in accordance with Finder's instructions.

Amazon Alexa, Google Assistant and Smart Home Heating Control

The Finder BLISS2 Smart Thermostat can integrate with Amazon Alexa and Google Assistant, providing convenient voice-based temperature adjustments when used with the appropriate Finder gateway and configured voice assistant integration.

For example, once the thermostat has been correctly configured and recognised by the voice assistant, users can issue commands such as "Alexa, set the living room temperature to 25 degrees" to change the required temperature without using the thermostat controls or opening a smartphone application.

The second-generation Finder 1Y.GU.005.1 YESLY Gateway provides the connection between the thermostat, the household Wi-Fi network and the supported smart-home services. The gateway communicates with BLISS2 using 868 MHz radio frequency technology and connects to the internet using 2.4 GHz Wi-Fi.

This arrangement also allows compatible Finder YESLY lighting, shutter and other smart-home devices to be managed within the wider Finder connected-home ecosystem.

Timed voice commands: BLISS2 supports timed manual temperature settings locally, but availability of specific Alexa commands requesting an exact duration, such as 25°C for 90 minutes, depends on the supported voice assistant integration. This functionality should be verified rather than assumed.

For remote operation and supported voice commands, the gateway must be correctly installed, connected to the internet and associated with the thermostat through the appropriate Finder application and account configuration.

Boiler Compatibility and Heating System Integration

The Finder 1C.B1.9.005.0007 thermostat is suitable for integration with heating systems that provide a compatible conventional ON/OFF control interface. Potential applications include gas combi boilers, system boilers, conventional central heating systems and suitable heating-zone control arrangements. Finder states that BLISS2 can interface with traditional radiator, underfloor, heat pump and fan coil systems.

The thermostat incorporates a volt-free changeover relay contact rated at 5 A, 250 V AC. In a conventional wired installation, this contact can be used to provide a heating demand signal to compatible boiler controls, valves or other switching equipment.

Compatibility is determined by the actual boiler model, its control interface and the electrical requirements of the heating installation. A boiler manufacturer may offer different thermostat connection arrangements across its product range.

Important: The BLISS2 should not be assumed to connect directly to every boiler. Systems that require OpenTherm modulation, proprietary digital communications or a specific manufacturer control interface may not accept conventional relay switching without an appropriate control arrangement.

For installations where running a control cable between the room thermostat and heating equipment would be inconvenient, Finder offers the 13.21.8.230.S000 wireless radio actuator. This compatible accessory can provide remotely located switching for suitable heating and cooling arrangements, subject to the system design and installation requirements. Finder specifies that the actuator is used together with the BLISS2 thermostat and a second-generation gateway.

The complete heating-control arrangement should be checked against Finder's technical documentation and the boiler manufacturer's installation instructions before connection. Fixed electrical wiring and boiler control connections should be installed and commissioned by a competent professional.
