Frequently Asked Questions - KWH4209 Kunft

How do I install the KWH4209 heater?

Drill two holes on the wall about 1.8 m from the floor. Insert the supplied plastic anchors (6 mm diameter) and fix the hooks with screws. Then slide the heater onto the hooks until it locks. Ensure the air outlet faces downward.

Can I use the heater in a bathroom?

The heater should be installed at least 1.8 m above the floor and away from water sources. It is not designed for humid areas; do not use in bathrooms or near showers.

What do the different modes mean?

Mode I: low power (about 1500 W), Mode II: high power (2000 W), ECO: maintains room temperature at 18°C for energy saving. Press the MODE button to cycle.

How does the window open sensor work?

If the room temperature suddenly drops by at least 10°C, the heater automatically switches off to save energy. It reactivates when the temperature stabilizes. This function can be enabled/disabled via the remote control.
