POWER ON/OFF

When you place 4 AA batteries in the back of the device, the display is switched on automatically. Booting takes about 2 seconds. The measured values are then refreshed every 10 seconds. Thereafter you are then in normal mode. To switch off the device, remove the batteries again.

Caution

The device does not have a backup battery. All functions such as AVG, date and time are reset after every power on/off.

Note

The following settings can only be made when the device is on.

MIN/MAX/AVG

This device enables you to check the minimum, maximum and average values. Press the MODE

key briey to switch between minimum values (MIN), maximum values (MAX) and average values

(AVG). The AVG function always calculates the average of the last 7 days. The value must then be reset and the calculation begins anew for the next 7 days.

Caution

The AVG function can only calculate the value of the last 7 days; after these 7 days, only - - - is shown in the display when the AVG value is called up. Calculation of AVG has stopped.

When the measured values MIN/MAX/AVG are shown in the display, the clock always shows the current time. It does not show the times when the measurement was too high or too low (MIN/MAX).

To reset the measured values MIN/MAX/AVG, press the SET key for 2 seconds while on the required

value. Every measured value can be reset separately. To do so, simply switch between the measured

values with the MODE key and press the SET key for 2 seconds.

Programming

Various functions can be programmed in the HD1 device. To program the temperature unit,

alarm parameters and high/low alarm threshold, press the SET key for 5 seconds to call up the

programmable settings. Move between the individual settings with the two arrow keys (UP/

DOWN). Press the SET key to adjust a parameter. To leave the programming menu, press the SET key again for 5 seconds.

Alarm Parameters

The device has an audible alarm and an alarm light to warn you when the set alarm parameter has been exceeded.

To select the required alarm parameter, press the SET key when in the menu P1.0 (PA). You can

then switch between the alarm parameters (P1.1) Temperature, Humidity and Low Dew Point with

the UP / DOWN key. You can then select the parameter you require with the SET key.

The alarm settings can be made in the menu P2.0 (ALA). You can switch the alarm on and off in P2.1. You can enter the high alarm threshold in the menu P2.2 (Hi). You can enter the low alarm threshold

in the menu P2.3 (Lo).

SHORT INSTRUCTION MANUAL

☞

HD1 – Thermo Hygrometer Display

General Description

Congratulations on your purchase of the

new ROTRONIC HD1 display. Read this short

instruction manual carefully before using the device. The document is restricted to a description of the main functions and installation of the device.

The HD1 is a precise display that can show the relative humidity, temperature and dew

point, has MIN/MAX/AVG functions and can

emit alarm signals.

Dimensions

120

Mechanical Installation / Position

There are two ways to mount the device: it can be hung on a wall using the two fastening points

at the back of the device or placed on a at surface using the stand that can be moved in and out

at the bottom of the HD1.

Function Keys

MODE

- Press the key briey to switch between MIN/MAX/AVG value.

- Press the key for a longer time to show the dew point value (Td).

Switch Between Dew Point & Humidity

When the device is on, press the MODE key for a longer time to switch between low dew point (Td) and relative humidity (%RH).

Up/Down

- Press the keys to move between the different functions in the device settings or to dene a range

for the alarm settings.

SET

- Press the key for 5 seconds to open the device settings.

- Press the key again for 5 seconds to see the current measured values again.

When one of these alarm parameters has been selected and switched on in menu P2.1, a bell symbol is shown in the normal standard operating display and the selected parameter (Tempera-

ture, Humidity, Dew Point) ashes every 3 seconds. If the measured value is above or below the set threshold, the symbol H or L appears in the display and ashes every second. The audible alarm (beeper) is also emitted every second for 1 minute,

and then every 10 seconds. The alarm functions do not stop on their own; they must be reset

manually. To stop the alarm functions manually, press the SET key for 2 seconds.

Temperature Unit Settings

This device allows you to select between two different temperature displays. When you are in menu

P3.0, press SET. You can then change the temperature unit from °C to °F in the menu P3.1; conrm by pressing SET again. The temperature is then always shown in the standard display in the unit set.

Date/Time Settings

When the device is on, press the SET key for 5 seconds to open the device settings. Then press UP/DOWN until you reach the menu P4.0 and conrm with the SET key. In the menu P4.1 you can select between the format 24h or 12h. Conrm with the SET key and then move to the next menu

P4.2 with the arrow keys to select the date format. The date is entered in the menu P4.3. The time is entered in the menu P4.4.

General

The standard display is refreshed every 10 seconds. This applies to the parameters that are to be measured. The time and date are refreshed in the following order: time 10 s - date 10 s - time 10 s - date 10 s.

If the battery voltage is too low or the batteries have become discharged, the symbol LOW appears

at the bottom right in the display to inform you that the batteries need replacement.
