PROGRAMMABLE TEMPERATURE DETECTOR
td-1_en 10/14
1. Applications
The detector can measure temperature and can be used to provide information on: too low temperature, e.g. in greenhouses , flower shops, children's rooms, etc.; too high temperature, e.g. in cold rooms, warehouses or spaces where high temperatures can cause malfunction of electrical equipment, etc.; too rapid temperature change, e.g. a quick temperature rise in cold room, etc.
2. Features
Supports two independent temperature sensors: built-in sensor, probe connected to a terminal on the electronics board. The probe can be mounted outdoors. Temperature measurement range from - 35 °C to + 60 °C. Programming of two critical temperatur e thresholds for each of the sensors: high (H) – warning of temperatures higher than the defined threshold temperature; low (L) – warning of temperatures lower than the defined threshold temperature. Programming permissible temperature change at a specific time for each of the sensors – warning about too rapid a change in temperature. Optional connection of a bistable switch (ins tead of the probe), whic h will enable toggling between the two sets of critical parameters for the internal sensor. Four-digit LED display. Programming using three buttons. 2 programmable relay outputs. Built-in sounder. Tamper protection against opening the enclosure. Small enclosure with attractive design. Supply voltage 12 V DC (±15%).

4. Installation
All electrical connections may only be made with disconnected power supply. The tools to be useful during installation include: flat blade screwdriver, 1 mm, tweezers, precision pliers. The TD-1 detector should be installed in cl osed spaces with normal air humidity. The waterproof probe can be installed outdoors.
1. Open the enclosure and re move the electronics board.
2. Make the openings for screws and wires in the enclosure base.
3. Pass the wires through the prepared openings.

5. Fasten the electronics board.
6. Connect an external probe (F ig. 2: S1 – red wire and the screen (covered with black heat

9. Close the enclosure.
10. Turn on the detector power.
5. Operation
The display always shows the current temperatur e. If the external probe is connected, you can use the and buttons to select the sensor t he temperature from which will be presented. temperature from the internal sensor. If both sensors measure the temperature in the same ro temperature from the external sensor. Note: om, the difference between re from internal sensor and information about the currently enabled set of critical parameters. the temperature readouts from the sensors can be 1 °C. If a bistable switch is connected, the display will present the temperatu the first set. the second set.

The following messages may be also displayed: internal sensor fault. the external sensor is faulty or disconnected. This message can be displayed in the event of incorrect configuration of the S1-S3 input (see description of the function F9 p. 6). the external probe is not supported by the detector (see description of the function F9 p. 6). 5.1 Sound signaling
1 short beep – pressing the or button,
3 short beeps:
obtaining an access to installer menu; pressing the button; automatic exit from the menu. intermittent tone – alarm. 5.2 Alarm In case of an alarm, the displa y will show alternately: the current temperature and the name of function in which th e critical parameters have been defi ned. To turn the audible alarm off, press the button. The function name will be disp layed until the temperature conditions return to the acceptable range.
6. Programming
Notes: If no button is pressed for 45 seconds, the menu will be automatically exited (changes that have not been accepted will not be saved). If the S1-S3 input supports a bistable switch (see F9 function description), the critical parameters programmed for the external sens or will become a second set of critical parameters for the internal sensor. 6.1 User menu The user functions allow pr ogramming the low and high te mperature thresholds. The temperature thresholds are distinguished as follows: high temperature threshold for the internal sensor; low temperature threshold for the internal sensor;

high temperature threshold for the external sensor; low temperature threshold for the external sensor.
1. To gain access to the user functions, press and hold down the button for about
4 seconds.
2. Select the threshold to be programmed, using the and buttons. Confirm with the
button. The temperature digits will start flashing.
3. Set the desired temper ature value, using the and buttons. Confirm with the
button.
4. Program the other temperature thresholds in the same way.
5. Scroll through the functions until the END message appears. Press the button to exit
the menu. 6.2 Installer menu In order to gain access to the installer functions, press and hold down the and buttons simultaneously for about 10 seconds. Function F1 will be displayed. To scroll through the list of functions, use the and buttons. To start the selected function, press the button. To edit the parameters of the function, use the and buttons. Use the button to confirm the changes made. To exit the edit mode, scroll the f unctions until the END message and press the button. The functions allow you to program: F1 - high temperature threshold for the internal sensor. F2 - low temperature threshold for the internal sensor. F3 - high temperature threshold for the external sensor. F4 - low temperature threshol d for the external sensor. F5 - permissible temperature variation range fo r the internal sensor (from 1 to 10 °C). F6 - time period during which the temperatur e variation programmed with function F5 can take place (from 2 to 60 minutes). F7 - permissible temperature variation range fo r the external sensor (from 1 to 10 °C). F8 - time period during which the temperatur e variation programmed with function F7 can take place (from 2 to 60 minutes). Note: The rate of temperature change will be controlled proper ly, if the parameters are programmed in functions F5 and F6 for the internal sensor, and in functions F7 and F8 – for the external sensor. The rate of temperature change is analyzed every minute. F9 - input S1-S3 function. F10 - relay output 1 function. F11 - relay output 2 function. F12 - alarm.
