An S1–S2 multifunctional input allows connection of an additional sensor, such as a floor temperature or external air sensor. The binding function enables a wireless and direct connection to receivers (e.g., control modules, actuators, or relays) via the HERZ Thermiq Gateway.
Devices can also be controlled via wired connection directly from the thermostat. For wireless operation, the HERZ Thermiq App and an internet gateway are required. The thermostat may also function as a standalone unit, connected by wires to the controlled device without the need for an internet gateway.
Product highlights
• Modern smartphone-inspired design
• Large, easy-to-read display with side-mounted function buttons
• Perfect fit for contemporary interiors
• Equipped with advanced control algorithms for precise temperature regulation
• Ideal for underfloor heating applications
• Programmable via the HERZ Thermiq App (using the HERZ Thermiq Connect gateway)
• Voice control supported through Amazon Alexa and Google Home
• S1–S2 input for additional sensor connection (e.g., floor or external air sensor)
• Integrated humidity measurement and display
