• Mounting base with power electronics. • Mounting frame is an additional part to complete the installation for RDF800KN/NF. The rear of the mounting base contains the screw terminals. Slide the front panel in the mounting base and snap on. -
Page 10: Engineering Notes
• Mount the room thermostat on a clean, dry indoor place without direct airflow from a heating / cooling device, and not expose to drips or splashes water. • For RDF800KN only, in case of limited space in the conduit box, use the mounting spacer ARG70.3 to increase the headroom by 10mm. -
