cally to prevent mould or rot from forming in the sauna room. This involves
heating the sauna room to 80 °C with the fan running for 30 minutes.
Instructions for installation and use p. 10/38
Excess temperature fuse
The excess temperature fuse is installed in the housing for the heater sen-
sor. Should the sauna heater continue heating after reaching the preferred
temperature due to a defect, the excess temperature fuse switches the sauna
3.4. Sauna operating modes
The sauna control unit Pro B3 provides two operating modes, sauna mode and
combi mode.
Sauna mode
Dry heat is provided in sauna mode. The temperature in the room is high (80 to
100 °C) The humidity level of maximum 10 % is low.
Combi mode
The evaporator operates along with the sauna heater in combi mode. The
temperature in the sauna room is lower (approx. 40 to 65 °C) than in sauna
mode, with the relative humidity being considerably higher, spanning 35 % to
approximately 70 %. The maximum humidity level which can be set depends on
the temperature of the sauna. The higher the sauna temperature, the lower the
maximum humidity level which can be set.
3.5. Sensor operating modes
The sauna control unit can be operated with one or two sensors. A temperature
sensor (bench sensor, F2) or a humidity sensor (FTS2) can be used as the
second sensor.
Single-sensor mode (F1)
time (see 8.3. Activating/deactivating the single-sensor mode on page 25).
In single-sensor mode, the sauna control unit is operated with the heater sensor
with excess temperature fuse (F1) only. This is included in the scope of delivery.
EN
Instructions for installation and use p. 11/38
In single-sensor mode, the sauna control unit only displays the set temperature
as standard. The actual temperature is not displayed. Should the sauna control
unit display the temperature above the heater (F1) as an actual temperature in
8.5. Displaying the heater temperature in single-sensor mode on page 26)
The maximum humidity level which can be set is based on the temperature above
the heater, and the humidity is timed. Only the set value for the humidity level (in
% of relative humidity) is displayed by the sauna control unit. The actual humidity
level in the sauna room when humidity is timed depends on the size of the room
and the evaporator capacity, and may deviate from the set value.
Two-sensor mode with bench sensor (F2)
In two-sensor mode with bench sensor, a second temperature sensor (bench
sensor) is installed above the rear sauna bench. The sauna control unit displays
the temperature measured by the bench sensor as the actual temperature.
In two-sensor mode with bench sensor, the humidity is timed. Only the set
value for the humidity level (in % of relative humidity) is displayed by the sauna
control unit. The actual humidity level in the sauna room when humidity is timed
depends on the size of the room and the evaporator capacity, and may deviate
from the set value.
Two-sensor mode with humidity temperature sensor (FTS2)
When a humidity temperature sensor is used in two-sensor mode, the sauna
control unit displays the temperature which is measured by the humidity tem-
perature sensor as the actual temperature.
In two-sensor mode with humidity temperature sensor, the evaporator is
regulated in accordance with the humidity level measured in the sauna room.
The actual value for the humidity level (in % of relative humidity) is displayed by
the sauna control unit.
Installation instructions, only for experts p. 12/38
4. Installation
4.1. Installing the sauna control unit
Observe the following points when installing the sauna control unit:
The sauna control unit must be installed outside the sauna room or in accord-
ance with the recommendation issued by the sauna manufacturer.
The ambient temperature must be within a range spanning -10 °C to +40 °C.
The sensors may only be connected using the sensor wires provided with the
unit, which are heat-resistant up to 150 °C.
ATTENTION!
Damage to the unit
The sauna control unit is protected against jets of water, however direct contact
with water could still damage the unit.
Install the sauna control unit in a dry place at which a maximum humidity of
95 % is not exceeded.
The sensor wires may be extended under the following conditions:
When a silicon wire resistant to temperatures up to 150 °C is used.
The minimum cross-section of the wire is 0.5 mm2.
The length of the heater sensor wires may NOT exceed 10 m.
ATTENTION!
Sources of interference can have a negative eect on signal transmission
Lay all sensor wires separately from other mains wires and control wires.
Protect wires with only one layer of insulation by using a pipe (double insulation).
