Water after-heating element
An after-heating element is necessary if you want to control the supply air temperature.
The water 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 (+)
2. User selection 1
1. GND
ATTENTION
The after-heating element must be activated in the Software under Basic settings.
