Installation Of The Sensor; Mounting The Door Sensor; Resetting The Overheat Protector - Harvia Xenio Instructions For Installation Manual

Terminals for controlling electrical heating
The power unit interface J (Figure 2) can also be used for purposes such as electric heating control. When the heater
is turned on from the control unit, voltage is generated in terminal J. The heating can be switched on or off based on
the signal.
Installation of the Sensor › Image 4
NOTE! Always check the correct location of the temperature sensor from the heater's installation
instruction.
• See image 4A
• Note! Do not install the temperature sensor closer than 1000 mm to an omnidirectional air vent or closer
than 500 mm to an air vent directed away from the sensor. See figure 4B. The air flow near an air vent
cools down the sensor, which gives inaccurate temperature readings to the control unit. As a result, the heater
might overheat.
Mounting the door sensor › Image 5
Installation of a sensor on a door frame:
• Attach the sensor holder to the door frame, using either a screw (Figure 5A) or double-sided tape (Figure 5B).
• Install the sensor in the holder (Figure 5C).
• Note: If the door frame is sheet metal and there is room for the sensor behind it, the sensor can also be attached
using a grommet (Figure 5D). An 8 mm drill bit should be used.
Attaching the magnet to the door:
• Fix the magnet holder to the door, using either a screw (Figure 5E) or double-sided tape (Figure 5F).
• Press the magnet into place in the holder (Figure 5G).
• The magnet can also be mounted on the door using only double-sided tape (Figure 5H).
Resetting the Overheat Protector › Image 6
The sensor box (WX232) contains a temperature sensor and an overheat protector. If the temperature in the sensor's
environment rises too high, the overheat protector cuts off the heater power. Resetting the overheat protector is shown
in figure 6.
Note! The reason for the going off must be determined before the button is pressed.
