Service intervals
Allows to set the intervals for servicing and maintenance. Upon expiry the control panel will re-
mind the user for a short time upon every switching about the pending servicing. The end user can
check the remaining time to the next servicing in the extended settings menu. This function allows
as well to keep track of the total operation time of the sauna.
Default setting for private use - 500 hours.
Default setting for commercial use - 2500 hours.
Fan
Here you can set the fan operation speed in 3 stages or disable it. If activated, the fan will automati-
cally switch on with the heater (synchronous operation). In “sauna dry“ program the fan will always
operate at the highest speed.
Refilling time (only H models)
Here you can set the grace time which the end user has to refill the vaporizer after the water short-
age alarm. If the vaporizer has not been refilled within this time, it will be switched off (overheating
protection). This function is especially important for Bi-O heaters with manual refilling.
After-heating time (only H models)
Here you can set the time for the “sauna dry“ program after the humid operation. Factory default
setting is 30 minutes. After every humid operation the sauna will then switch on in dry Finnish
mode, in order to dry the cabin. We recommend to use this function in combination with the ex-
haust fan, in order to remove the humidity and dry the sauna cabin.
After-heating temperature (only H models)
This functions allows to set the temperature for the “sauna dry“ program. Factory default setting
is 90 °C.
Fan running time (only H models)
Here you can set how long the fan should operate after the Finnish or humid mode operation of
0-60. Factory default setting is 30 minutes. We recommend to use this function in combination
with the “sauna dry“ program, in order to remove the humidity and dry the sauna cabin.
Hysteresis
Allows to adjust the hysteresis within a 1-10 K range. This adjusts the tolerance level around the
temperature set-point and influences how often the heater will be switched on or off by temper-
ature changes. For instance at 90 °C target temperature and hysteresis set to 5 K the control unit
will switch the heater on at 85 °C and off at 95 °C respectively. This allows you to better adjust the
sauna heater to the specific sauna cabin size and layout.
