Product description
Universal on/off temperature controller for heating and cooling. Function for monitoring min. and max. temperature. Equipped with 4 potential-free changeover contacts (NO/NC), 2 of which act as alarm contacts for temperature monitoring. The price includes 2 temperature sensors.
For heating and cooling
Based on the switch-on and switch-off temperatures, the controller determines whether heating (heating cables) or cooling equipment (air conditioning) needs to be switched. You can set these switch-on and switch-off temperatures (hysteresis) yourself.
Applications
Menu-driven operation
You can easily operate the temperature controller using the 4 buttons on the front panel: OK/YES, ESC/NO, Up and Down. The display shows the switching temperatures, the actual (measured) temperatures, set parameters and minimum & maximum values. The latter serves as the memory for the highest and lowest measured temperature.
Temperature controller with 4 switching contacts
The temperature controller has four potential-free (isolated) changeover contacts, which are suitable for 230 volts or a lower voltage. The temperature controller can itself trigger an alarm if the measured temperature falls outside the set range (after an adjustable delay time of up to 8 hours). This is useful, for example, for temperature monitoring in an animal enclosure or product storage.
Temperature controller adjustable per channel
Each channel has its own relay for switching and monitoring. There are 3 LED indicators per channel: relay-on / alarm / fault. The built-in buzzer can be used for the alarm (optional).
You can also use this temperature controller as a (passive) 2-channel temperature meter (digital thermometer), for example for cooling and storage of products. Other application: pump control for a swimming pool with solar collector.
Temperature controller with 7 settings
- digital temperature meter for channel 1
- digital temperature gauge for channel 1 + 2
- temperature switch on channel 1
- temperature switch on channel 1 + 2
- differential temperature controller
- circulating pump control
- manually (other applications)
* modes 3, 4, 5, 6 are with alarm function.
Switching can take place at any temperature within the range of -55 to +125 °C. Between -10 and +85 °C, this temperature controller is accurate to within half a degree. Set temperatures are retained in the memory if the mains voltage fails.
Temperature sensors up to 50 m away
The temperature controller is intended for wall mounting and has 2 sensor inputs. It also works when only one (1) sensor is connected. The sensor cable (with RJ45 plug) is 2 metres long.
The sensor connection wires can be extended to as much as 50 m. This can be done as follows: cut the sensor cable and, using 2 junction boxes make the desired extension using 4-core signal cable. Another option is to extend it using standard RJ45 computer cables.
Please note: For some products in our webshop, a basic knowledge of electrical engineering is required.
Knowledge of German and some experience in electrical and control engineering are required for connecting and commissioning the temperature controller
