1.1. General

The purpose of Harvia Xenio control unit is to con-

trol an electric sauna heater within an output range

of 2.3–18 kW. The control unit consists of a con-

trol panel, a power unit and a temperature sensor.

See figure 1.

The control unit regulates the temperature in the

sauna room based on information given by the sen-

sor. The temperature sensor and the overheat protec-

tor are located in the temperature sensor box. The

temperature is sensed by an NTC thermistor and the

overheat protector can be reset ( 3.4.).

Panel lock can be activated only

in standby mode. Panel lock also

prevents remote start.

2.5. Remote control

According to the product standard IEC/EN 60335

-2-53 regulating electrical sauna heaters, a control

unit can be used to remotely control the heater

once the heater is equipped with a secure switch

(safety switch).

Using with a safety switch: the heater can be

turned on remotely, if the safety switch circuit is

closed. If the circuit is open, "SAFE" is displayed

and the heater will not start.

Pause time: These features are limited by a pau-

se time that prevents the heater from turning on

if it has been less than 6 hours since the heater

was last turned off. Trying to remotely turn the

heater on during the pause time period (6 hours),

text ”rESt” is displayed. The heater can be remotely

started after the pause time has elapsed and ”rc”

is displayed.

Memory for power failures: the control unit resu-

mes operation, if the remote switch has remained

in ON position.

Preset time: if the control unit is on preset delay

time, it cannot be controlled with a remote switch.

After the preset delay has passed and the heater

is turned on, it can be turned off with a remote

switch.

Dehumidifying: when the heater is turned off re-

motely and dehumidifying is enabled, dehumidify-

ing starts and cannot be stopped remotely. When

dehumidifying is in progress and a safety switch

is used, the heater can be turned on remotely. If a

door switch is used, the heater cannot be remotely

started, as the remote use mode must be re-activat-

ed by pressing and holding the control unit's heater

button for three seconds.

3. INSTRUCTIONS FOR INSTALLATION

The electrical connections of the control unit

may only be made by an authorised, professional

electrician and in accordance with the current

regulations. When the installation of the control unit

is complete, the person in charge of the installation

must pass on to the user the instructions for

installation and use that come with the control unit

and must give the user the necessary training for

using the heater and the control unit.

3.1. Installing the Control Panel

The control panel is splashproof and has a small

operating voltage. The panel can be installed in the

1. Thread the data cable through the hole in the back cover.

2. Fasten the back cover to a wall with screws.

3. Push the data cable to the connector.

4. Press the front cover into the back cover.

Figure 4. Fastening the control panel

washing or dressing room, or in the living quarters.

If the panel is installed in the sauna room, it must

be at the minimum 500 mm safety distance from

the heater and at a maximum height of one metre

from the floor. Figure 4.

Conductor tubing (ø 30 mm) inside the wall struc-

ture allows you to thread the data cable hidden

within the wall – otherwise the installation will have

to be on the wall surface. We recommend you to

install the control panel embedded in to the wall and

far away from possible splashes.

3.2. Installing the Power Unit

Install the power unit to a wall outside the sauna

room, in a dry place with an ambient temperature

of >0 ºC. See figure 5 for instructions on how to

open the power unit cover and how to fix the unit

to the wall.

Note! Do not embed the power unit into the wall,

since this may cause excessive heating of the in-

ternal components of the unit and lead to damage.

See figure 5.

3.2.1. Electrical Connections

Figure 6 shows the electrical connections of

the power unit. For more detailed installation

instructions see the instructions for installation and

use of the selected heater model.

Figure 5. Opening the power unit cover and mounting the unit to a wall

3.2.2. Power Unit Fuse Faults

Replace a blown fuse by a new one with the same

value. The placement of the fuses in the power unit

is shown in figure 6.

• If the fuse F2 for the electronic card has

blown, there is likely a fault in the power unit.

Service is required.

• If the fuse in the line F1, F3 has blown, there

is a problem with lighting or fan. Check the

wiring and functioning of lighting and fan.

3.2.3. Power extension unit LTY45J (optional)

The maximum load of control unit can be increased

by 18 kW by using power extension unit LTY45J.

It is controlled using terminals A1, A2, A3 and A4.

The power extension unit includes detailed instruc-

tions of installation.
