Wireless devices monitoring temperature, humidity, light and energy

By Anonymous -
The Carel rTM monitoring system, is used to monitor temperature, humidity, light intensity and pulse counters from energy meters modules, in combination with Carel, supervisory systems or programmable controllers with special software.

Benefits
Ideal for retrofits on existing systems, being easy to install:
-    No electrical connections required;
-    Flexible layout in the event of structural modifications;
-    Simple installation and maintenance;
-    Existing controllers do not need to be replaced, as the system is completely independent and can be integrated into any installation;
-    Simplifies monitoring of the installation (including over remote connections). In the event of alarms, operating status can be notified via SMS, email, FAX;
-    Supervisory systems can be customised reports and data log files;

Composition
-    Battery or mains powered sensors for measuring the temperature of cabinets and cold rooms (°C). Available in versions with built-in sensors (BP) and external sensors (EP);
-    Battery powered sensors for measuring temperature, humidity, light intensity in rooms, type SA (°C – RH%) or SI (°C – r.H% - Lux).
-    Pulse counter from energy meter modules for monitoring electricity, water and gas consumption, battery powered (CI) or mains powered (RC).
-    RA (Router-Actuator) I/O module, to measure the status of the inputs and activate general loads. Can be configured as a thermostat with direct/reverse logic.
-    RB (Router-Bridge) to connect instruments locally over Modbus® RS485 that are not accessible to cabled lines.
The devices use a 2.4 GHz wireless connection (16 channel, 2405 to 2480 MHz) with ZigBee communication protocol and MESH networks within up to 7 hops, automatic adaptation of communication between devices, optimising wireless communication routes when the devices are not directly reachable from the Access Point, so as to guarantee continuous communication.
Battery or mains powered sensors. The battery powered sensors require no electrical connection and typical battery life is 5/8 years; mains powered devices require no routine maintenance.
All wireless sensors send the data measured to the Access Point via radio; this acquires information from the sensors and then forwards it to the Carel supervisory system or controller, over the Modbus® RTU RS485 serial network.
The system can be easily extended and modified following installation.
Handheld configuration devices are available for simple configuration and installation.
To increase wireless coverage, Routers are available that extend the area of transmission. These devices are available as Routers only, RO, or combined with other functions:
-    EP1 Router-Sensor (same functions as the EP sensor);
-    RB Router-Bridge type (to extend the RS485 wired network);
-    RA Router-Actuator, to manage I/O via a remote connection or used as a local thermostat monitored via the wireless network.

CAREL and the dreaded 'NO LINK' Screen!

CAREL and the dreaded 'NO LINK' Screen! Picture the scene, you've just downloaded a fresh new piece of software onto a controller but rather than the a new interface, you're met with a big fat 'NO LINK' message on the display. Or maybe you've just ran a factory reset to default settings and have come up against the same issue?  These are all possible causes for the common problem encountered by many of our customers, deemed the 'NO LINK' screen! (capitals for emphasis) As well as the two already mentioned, other common causes of the issue are a result of: A faulty connection between the Controller and the Display A faulty Controller  In any case, this issue is relatively simple to fix and our Managing Director, Stefano - having been in the Industry for 15+ years - has put together a video guide on how to do so. Watch the video below to see how to overcome the dreaded 'NO LINK' Screen!   www.i-acs.co.uk

For those who think that the new generation of innovative, automated HVAC control systems are a far-off thought, think again!  The new c.pCO Range by CAREL marks the arrival of their most intelligent range of controllers yet. Despite their compact design, the c.pCO Controllers are packed with new and exciting technologies offering a highly integrated solution to any kind of BMS System.  The versatile nature of the new standard controller (2 Ethernet, USB & RS485 Inputs Built In) opens doors to a wide range of communication protocols such as Modbus, BACNet,  HTTP, FTP  and loads more. The video below offers a detailed look into the new features and benefits of the c.pCO range. Worried about having to do a lot of work to replace older controllers? As if this wasn't enough, all c.pCO Controllers offer pin-to-pin compatibility with pCO5+, pCO5 and pCO3 controllers.  Get in touch now for more information! Peter Campbell Marketing

1tool is the development system for the Carel programmable control platform, consisting of six different environments in which the designer manages the application software in all its different stages: from design to simulation, to testing and debugging, to arrive at commissioning in the field. A fundamental feature of 1tool is integration. Because all the different environments are interconnected to best support development of the application software. Each environment is in fact dedicated to the realisation of a specific function and interacts with the others to offer the designer: -  Greater reliability thanks to real-time error notifications in the design stage; - Reduced development time using the advanced functions offered, first and foremost the new libraries of functional modules specific for HVAC/R; -  Flexibility in terms of software customisation. All these features, an intuitive graphic interface and user simplicity make 1tool an excellent product, responding to th
