3.4. Sauna operating modes

The sauna control unit home.com4 provides two operating modes: sauna mode
and combi-mode. If no vaporizer is connected, the menu item for operating the
vaporizer can be hidden (see "9.1. Technician menu" on page 33).
Sauna mode
Dry heat is provided in sauna mode. The temperature in the room is high
(80 to 100 °C) The maximum humidity level of 10% is low.
Combi-mode
The vaporizer operates along with the sauna heater in combi-mode. The temper-
ature 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 tempera-
ture 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 units of the home.com4 series can be operated with one or
two sensors. A temperature sensor (bench sensor, F2) or a humidity sensor EN
(FTS2) can be used as the second sensor.
Single-sensor mode (F1)
The maximum humidity level which can be set in single-sensor mode 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 vaporizer capacity and may deviate
from the set value.
