3.4. Sauna operating modes
The sauna control unit home.com4 provides two operating modes: sauna mode
and combi-mode. If no evaporator is connected, the menu item for operating the
evaporator can be hidden (see “9.1. Technician menu” on page 33 ).
Sauna mode
Dry heat is provided in sauna mode. The temperature in the cabin is high
(80 to 100 °C). The humidity is low (no more than 10%).
Combi mode
The vaporizer operates along with the sauna heater in combi-mode. The temper-
ature in the sauna cabin is lower (around 40 to 65 °C) than in sauna mode, but
the relative humidity is much higher, ranging from 35% to 70%. The maximum
humidity that 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 units of the home.com4 series 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)
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 setpoint
for the humidity (in % relative humidity) is shown on the sauna controller display.
The actual humidity in the sauna cabin when the humidity is timed depends on
the size of the cabin and the evaporator output, and may differ from the setpoint.
