The heating capacity of the coil with only 2 rows is independent of the connection of the hot water in equal flow or in
counter flow to the direction of the air, but connection of the hot water to the pipe marked for inlet and the return
water to the pipe marked for outlet is very important to ensure that the sensor for transmission of the water tempera-
ture for frost protection really will be placed in a return circuit of the coil (Screw-joint for the water temperature sensor
is welded in the main collection pipe for return water).
Coils with 3 rows or more must always be connected in counter flow to the airflow.
Note:
If glycol is added, the glycol must be without additives and auto glycol must not be used. Automatic
bleeding has to be installed at the highest point of the 2 pipes supply or return pipe.
I.4.4.1.1 Video instruction about installation of sensor for frost protection of heating coil
To protect against frost a temperature sensor for the transmission of an analog signal to the controller is placed in a
pipe on the collection pipe for return water. For the frost protection of heating coil, the water temperature is transmit-
ted to the controller. The controller always must generate a signal to the valve motor that keeps a sufficient flow of hot
water to protect the coil against frost. This frost protection also must be activated when the running mode is “off”.
Note:
Instructions about easy, quick and safe installation of sensor for frost protection and cables is in a 3–minutes
video. The video is available on YouTube.
