Accessories
CB30N, fan speed switch (3 stage)
Controls the air flow in three stages. Supplied
in a separate enclosed unit for wall mounting.
Controls a maximum of 6 units. Rated current
10 A. IP44.
ADEA, air curtain regulator
ADEA is an advanced and user friendly regu-
lator for air curtains. Ready to run directly
after installation on account of the pre-pro-
grammed parameters. Outdoor sensor, room
sensor and door contact govern the regulator,
which adapts the heat and fan speed. The fan
speed is controlled in three stages. Supple-
mented with a control card
ADEAEB (IP55)
for external installation. ADEAEB must be
supplemented with a control card
ADEAGD
for compatibility with ADR. One ADEA is
needed for each opening, but it may control
several air curtains. IP30.
MDC, magnetic door contact with time
delay
Starts the air curtain or increases the fan
speed from low to high speed when the door
is opened. When the door is closed, the unit
continues running for the preset time (2 s -10
min). Prevents the fan from starting/stopping
continuously and is especially suitable for do-
ors that are frequently opened. Relay with th-
ree alternating volt free contacts 10A, 230V~.
Door sensor MDCDC is included. IP55.

fuses, circuit-breaker, time switch (if any)
that starts and stops the unit.

3. That the door contact is working (if instal-
led).
4. That the overheat protection for the mo-
tors has not been deployed.
5. That the intake grille is not dirty.
If there is no heat, check the following:
1. That there is hot water to the water coil.
(Check the circulation pump - if applica-
ble.)
2. That the heat demand exists; check ther-
mostat settings and actual temperature.
3. That the intake grille is not dirty
If the fault cannot be rectified, please contact
a qualified service technician.
