4.3 Function
The single room temperature controller is used to control the temperature in rooms with underfloor heating system (heating/cooling).
The product measures the actual temperature in the corresponding room. The reference temperature is adjusted via the rotary dial of the corresponding
product.
The product transmits the actual temperature and the reference temperature to the connection modules WL via wireless EnOcean®signals.
The product does not indicate heating and cooling via LEDs.
The product features a solar cell for energy supply. If the product is to be set up in dark environments, an optional battery
may be used (see “Technical data”).
Each product has a unique ID. If multiple products are used, the recipient can distinguish the individual products.
4.4 Approvals, conformities, certifications
The product complies with:
• EMC Directive (2014/30/EU)
• Low Voltage Directive (2014/35/EU)
