3.5. Factory settings

VALLOX 180 SE has the following factory settings

3.4. Week clock control

The week programme can be used to set the desired fan speed (basic fan speed) and supply air
temperature for each hour of the day on seven days a week. The week programme overrides
manual adjustments.
Carbon dioxide and humidity adjustment can increase fan speed but never decrease it below the
basic fan speed set in the week programme.

Example: Monday

Fan speed is increased to speed 2 and supply air temperature to 17 ºC between 07:00 (7 a.m.)
and 17:00 (5 p.m.) hours. After that, fan speed is raised to speed 4 and supply air temperature to
20 ºC. For the evening, fan speed is boosted to speed 6 between 19:00 and 21:00 hours (for the
period when a sauna bath is taken), after which fan speed is lowered back to 4.
Move the cursor with the arrow keys and change values with the + and – buttons. Note that Exit
and saving are done when the programming is finished by moving the cursor below the word Exit
and pr or –.

Changes in fan speed (Sp) and supply air temperature (Tmp) are only made for the hours desired;
in other cases, use N (no change to previous).

Monday (D = 1), 07:00 hours (H = 7), fan speed 2 (Sp = 2), supply air temperature 17 ºC (Tmp =
17). Move the cursor to the following hour.

Monday (D = 1), 16:00 hours (H = 16), fan speed 4 (Sp = 4), supply air temperature 20 ºC (Tmp
= 20). Move the cursor to the following hour.

Monday (D = 1), 19:00 hours (H = 19), fan speed 6 (Sp = 6), supply air temperature unchanged
(Tmp = N). Move the cursor to the following hour.

Monday (D = 1), 21:00 hours (H = 21), fan speed 4 (Sp = 4), supply air temperature unchanged
(Tmp = N). Move the cursor to the following day.
Similar changes have to be made separately for each day. Finally, exit the programming mode by
selecting Exit. If you wish, you can erase the week programme as indicated in section 3.3.3. You
can then start programming from the start. You can see the settings programmed by choosing a day
and by scrolling the hours with the + or – button.
