[. . . ] 2: 24 Hr - If you choose this option, the MIN/MAX values for the last 24-28 hours in each case are recorded. After expiry of this period, the MIN/MAX values that are older than 24-28 hours are removed from the memory. As soon as you have selected this option, we recommend that you start the memory recording in a defined way with a MEMORY RESET. This then starts a recording that triggers internally an elaborate calculation and recording. [. . . ] The start is determined by a MEMORY RESET and after 24 hours, the memory is automatically reset and a new recording begins. Example: You want to be able to read the MIN/MAX values of the last 24 hours in each case at 8 p. m. With this RESET, the clock begins to tick internally and this automatically resets the memory after 24 hours and starts a new recording. °C/°F - Changes the unit of temperature in the display from °C to °F or vice versa MEMORY RESET - Hold pressed for 3 seconds: Resets all memories (IN and CH1 . . . The new recording now begins depending on the setting of the MIN-MAX switch CH (=CHANNEL) - Press briefly: changes to display of the next channel (1 2 3 4 5 1 etc) - Hold pressed for 3 seconds. Only the sender of the channel displayed is searched for; the others remain unaffected. 31 32 Battery compartment 4. RADIO THERMOMETER The operation of the radio sensor supplied with the device is easy: - Open battery compartment - Select channel - Activate batteries (i. e. remove insulation strip) or insert batteries (please make sure that the polarity is correct!) - Close battery compartment again (please ensure that it is tightly closed!) 2 x 1. 5 batteries of the size AM-4 resp. "AAA" To open: slide lid in the direction of the arrow (indicated on the lid) after the stand has been removed. Other Irox radio sensors that are compatible with the HBR653: 3 channels (can be used on the channels, 1, 2 or 3) : HTS12C, HTS33, HTS13*, HTC13 5 channels (can be used on all 5 channels): HTS55, JKR-1 (*HTS13 is included in the scope of delivery of the HBR653 and can be used on the channels 1-3) With the sensors with thermo and hygrometer, simply only the temperature is displayed on the HBR653. 3. Put all radio sensors that you want to use into operation and place these in close proximity (1-2 metres) to the reception device. Open the battery compartment of the display device and remove all insulation strips. If no batteries are in the device, insert the 2 batteries (UM-3 or `AA' 1. 5 V) in the correct polarity. It is therefore recommended that new batteries are always inserted in the sensor at the beginning of the winter (alkaline type or better). whether disturbances or shields are to be found in the area of the sender/receiver or the distance between the two devices is too great. The search processes described above for a `lost' sensor do not have any influence on any other existing sensors that function without problems. 5. 1. 1 Reading of the temperature from each channel Briefly confirm the key CH to jump from channel to channel. - The next channel is thus displayed with each press of the key and activated for further operations. The sequence of the activation is CH1 CH2 CH3 CH4 CH5 CH1 This is independent of whether a radio sensor is available in the system or not. Please note: The measurement is always depicted in the lower window; channels 1-5 one after the other in the upper window. etc 35 36 5. 1. 2 MIN/MAX memory 6. CHANGE OF BATTERY : BATTERY CHANGE DISPLAY The batteries last for around 8-12 months. Depending on the usage of the appliance and the batteries used, this time can be slightly shorter or longer. In order to avoid a surprising and unpleasant interruption to operations, the battery symbol appears in the two temperature windows with the corresponding channel. This means that batteries of the display appliance (in the IN window) or of a radio sender (in the CHx window) are becoming too weak and need to be replaced. To change the batteries, please note Chapter 3 (Putting into operation). [. . . ] The environment will thank you for it! a) The MIN/MAX values are always present on the display below the current measurement value. - LEFT: Minimal (=lowest) temperature "MIN" - RIGHT: Maximum (=highest) temperature "MAX" The logic of the recordings is displayed in Section 2. 2 Operating elements. This occurs when a channel is not allocated or the sensor is no longer being received. 5. 1. 3 Comfort Zone The Comfort Zone is only displayed for the thermo/hygro measurement of the display device. With the outdoor sensors, only the temperature is received and displayed; it is thus not possible to calculate the Comfort Zone for CH1. . . CH5. [. . . ]
