5. Programmer

The programmer is composed of a two-piece wall mounting housing with display (LCD) and membrane keypad. The
display can read out 8 lines with a maximum of 21 characters per line.
The 1

line indicates the date, time and room temperature.

The remaining lines inform the user on the operating mode (manual or automatic), the current ventilation step and the
activated program.
The programmer includes an integrated sensor recording the room temperature. It also includes the connections for an
external boost switch, an external temperature sensor and another programmer.
Several programmers can be connected in series (maximum 5).
Cable lengths between the control unit and the programmer, or between programmers, should not exceed 15 metres.
If it is intended to record the temperature in a room where no programmer is installed, an external NTC sensor needs to
be connected to the first programmer. In such case, it is necessary to remove (cut off) the NTC sensor in the lower left
part of the programmer.
Always the temperature reading from the first programmer is evaluated for back-up heater and temperature indication.
The programmer can be used to view, enter, or change any parameters of the mechanical ventilation control unit.
The programmer offers menu dialogues; so all settings are self-explaining. There are two access modes: one for the
user and one for the service staff.
The user can just make a limited number of settings and validations only.
The system setup menu allows the service staff to change any parameters of the control unit.
The service staff has the option to connect to the first programmer a second service programmer giving access to all
parameters of each of the modules.
But no settings can be made with the service programmer. To activate the service programmer, a jumper must be
inserted into the two contacts next to the connector X1 on the HCE board.
