Electrical after-heating element
An after-heating element is necessary if you want to control the supply air temperature.
The electric after-heating element can be purchased for installation in the supply air duct and the necessary sensor, connection box
and connection to the ventilation unit are included. The wire from the heating element to the connection box (A) is 2 meters long and
from the box to the RJ45 plug there is 0.5 meter.
ATTENTION
The temperature sensor T7 is mounted after the heating element.
It is not necessary to purchase a CTS400 connection box, as the electric heating ele
-
ment is supplied with a connection box (A), where there are options for other connec
-
tions:
7. Fire input signal
5. Modbus B1 (-)
4. Modbus A1 (+)
3. Overheat protection
2. User selection 1
1. GND
ATTENTION
The heating element must be insulated with a fire retardant insulation material. The cover of the connection box, how
-
ever, must not be insulated.
