Week-clock control4.1 Week programme programmingThe week programme can be used to set the desired fan speed (base fanspeed) and supply air temperature for each hour of the day on seven daysa week. The week programme overrides manual adjustments.Carbon dioxide and humidity adjustment can increase fan speed but neverdecrease it below the base fan speed set in the week programme.Example: MondayIt is the intention to decrease fan speed to speed 2 and supply air tempera-ture to 17 ºC between 07:00 (7 a.m.) and 16:00 (4 p.m.). After that, fanspeed is raised to speed 4 and supply air temperature to 20 ºC. For theevening, fan speed is boosted to speed 6 between 19:00 and 21:00 (7p.m. and 9 p.m.), after which fan speed is lowered back to 4.4.2 Adjusting time© VALLOX • We reserve the right to make changes without prior notice.5.

Adjustment range is0–100%. However, fan speeds limitthe adjustment range as follows:If for instance speed 3 is 30%, speed 2 cannot be increased to morethan 29% and speed 4 cannot be decreased below 31%.The fan stops when the setpoint is 14% or lower. The adjustment is madewith the + and – buttons. There are 8 displays, one for each fan step.3.29 Moving to Operating menuTo Main menupress + and –To move back to the Operating menu,press the + and – buttons simultaneous-ly.Similar changes have to be made separately for each day. Finally, exit theprogramming mode by selecting Exit. If you wish, you can erase the weekprogramme as indicated in Section 3.6. You can then start programmingfrom the start.
