General

Due to the high recovery rate and to ensure frost protec-
tion in NIBE ERS, an electrical air heater must be in-
stalled.
EAH 20 is equipped with a temperature limiter that
automatically switches off the current if the temperature
exceeds 50 °C. In the event of falling temperatures,
the temperature limiter resets automatically.
For extra safety, there is an integrated thermal fuse
which disconnects when the temperature exceeds
100 °C. Reconnection is performed manually by pressing
the reset button on the junction box.

Mounting

EAH 20 (EB17) must be installed in the outdoor air duct
as illustrated.
BT23 EB17
The outdoor air sensor (BT23) in NIBE ERS must be
disconnected and replaced with the one supplied with
EAH 20.
The outdoor air sensor is installed approx. 500 mm
ahead of EAH 20 to prevent it from being affected by
radiated heat.
Note the following during installation:
NIBE EAH 20-1800 | GB
ERS
• Arrows for air direction and location of the junction
box must be followed. EAH 20 must never be installed
with the junction box downwards.
• The outer temperature of EAH 20 can reach 100 °C.
EAH 20 must not be installed directly under a wall
socket or near flammable objects, and must not be
covered during use. Take the high temperature into
consideration when selecting insulation material.
• The junction box must not be insulated against con-
densation or heat, because it will overheat. The dis-
tance from the junction box to the condensation insu-
lation should be at least 100 mm.
