MAXIAIR MXP-HPW & HPWI-IOM/1905-E
By entering page A02, there are 2 possible options:
-
Temperature control mode:
it allows to chose among Automatic (default), Hot, Cold, Ventilation only. The unit is equipped with a
regulation logic that controls all the actuators to produce hot/cold air, by comparing the different temperature probes. By using this
menu entrym it is possible to make the unit work only with the hot/cold actuators or to exclude them.
-
Running mode:
it allows to select the operating mode between heat recovery unit and UTA. In the heat recovery operating mode
(default), when the comparison between internal and external temperature allows it, the unit does not use the actuators to produce
heat/cold, because the only action of the heat recovery unit should be able to satisfy the needed thermal requirements. On the
other hand, in the UTA operating mode, the unit activates also the heat/cold actuators even when the only heat recovery should be
sufficient to reach the the required set point.
Menu B: Set Point
By entering this menu it is possible to program the required temperature set point.
Menu C: Clock
By entering this menu it is possible to set the current time and date, and to enter the pages for programming the time slots, if the
operating of the unit with turning on/off by time slots is selected.
Menu D: Input/Output
By entering this menu it is possible to visualize the condition of all the inputs/outputs of the unit. The outputs on/off are marked by the
symbols DOx, where x stands for the number of the output, whereas DIx identifies the on/off inputs.
The proportional outputs are marked by the symbols Aox, whereas the proportional inputs (as for example the temperature probes) are
identified by the symbols AIx.
For the correct meaning of each of them, please see the specific electrical wiring diagram.
Menu E: List of Alarms
By entering this menu it is possible to visualize the last 50 registered alarm messages.
Menu F: Substitution of the board
This menu is reserved to the manufacturer.
Menu G: Service.
By entering this menu and the corresponding subordinate menus it is possible to set the different operating parameters. For their
meaning, see the below table.
It has to be underlined that for the menus G and H the pages of the menus are marked by 2 letters and 2 numbers, where the second
letter specifies the subordinate menu, so for example Ga01 stands for page 02 of the subordinate menu “a” of the menu G.The access
to this menu is protected by password that is 0000.
Menu H: Manufacturer
This menu is reserved to the manufacturer.
