The ControlbyWeb X-300™ is two products in one. First, the X-300™ is a powerful web-based temperature logging instrument that allows you to monitor and control temperatures via an IP network. Up to 8 temperature sensors can be connected at a time, and temperatures can be viewed in real-time using a web browser. Second, the X-300™ is a 7-day programmable web-enabled thermostat. Users can adjust and set temperatures for heating and cooling systems and view temperatures from any web browser. Also supports Modbus TCP, SNMP, email alerts, relay control, and a BASIC interpreter.
X-300™ has two operating modes that can be configured in the field, Temperature Monitor and Thermostat modes.
The X-300™ can be used as a simple web-enabled thermometer for conveniently viewing temperatures on a computer or web-enabled mobile phone. This is useful for viewing the temperatures of living spaces, outdoors, refrigeration systems, tanks, or pipes
Temperatures can be configured to log data to internal memory on a scheduled or event-driven trigger. Email alerts (or indirectly, text messages) can be sent directly by X-300TM when programmable temperature thresholds are crossed. X-300™ can communicate directly with a custom computer application which can read the temperature data from the X-300™ for process control or other functionality using Modbus TCP or SNMP. High or low alarms can be set to activate email, the built-in relays or remote relays over the LAN (using another Controlbyweb relay device).
X-300™ can be used as a thermostat to control HVAC (Heating, Ventilation, and Air Conditioning) systems. The web browser interface allows users to access the thermostat from anywhere in the building or over the Internet. This is also limits access to only authorized users.
The thermostat Control Page (web page) looks like a professional grade thermostat and includes: indoor temperature, set temperature, outdoor temperature (if connected), high and low outdoor temperatures for current and previous days (if connected), current humidity (if connected), and other basic information. The user can adjust the set temperature from the Control Page.
