## Long description

Volt COMFORT HT-08 is a wired and Wi‑Fi thermostat engineered for underfloor heating systems. It combines a hardwired relay interface with wireless connectivity to provide local temperature sensing, programmable schedules and remote control from mobile apps or smart‑home platforms. The device is intended for residential installations where reliable floor and room temperature regulation is required to maintain comfort and reduce energy use.
Advantages
The thermostat supports both wired connection and Wi‑Fi remote management, enabling on‑site control and offsite adjustments. Its scheduling capability allows setting daily and weekly heating periods, improving energy efficiency by limiting heating to occupied times. The unit is designed for straightforward integration with common underfloor heating circuits and provides stable temperature regulation via dedicated sensors and output switching. The interface and app control simplify operation and monitoring of setpoint and actual temperatures.
Suitable for
Residential underfloor heating systems in single or multi‑room homes
Applications requiring scheduled room or floor temperature control
Smart‑home setups that use Wi‑Fi thermostats for remote management
Key specifications
Control type: wired relay output with Wi‑Fi remote control
Functionality: temperature sensing, programmable schedules, remote access
Installation: flush or surface mounting compatible with standard electrical boxes (check local installation requirements)
User interface: local controls for setpoint and schedule adjustment plus mobile app control
Compatibility: designed for electric underfloor heating systems and compatible with standard room/floor sensors
How to use
Install the thermostat according to the electrical and mounting instructions supplied by the manufacturer, ensuring the wired relay and sensor connections match the underfloor heating circuit. Configure the local setpoint and time schedules using the device controls, then connect the unit to the local Wi‑Fi network to enable remote control. Use the mobile app to create or adjust temperature programs, monitor current temperature readings and switch between manual and automatic modes as needed.
Usage recommendations
Place the floor or room sensor in a representative location away from direct sunlight, drafts and heat sources to ensure accurate readings. For energy‑efficient operation, use weekly schedules to reduce temperature during unoccupied periods and raise it shortly before occupancy. Follow all local electrical codes and, if unsure, use a qualified electrician for installation and wiring.
