Internet Module CS

The Internet module connects your boiler with an application that continuously monitors the boiler’s operation and also stores its operating history in easy-to-read graphs. It accurately displays the operation of the heating system components and, hence, you can change the set parameters. With this module, the heating can be activated remotely.

At the same time, the online system enables sending error and information messages to your smartphone.

You can preview our online system at www.opop.emodul.eu. After clicking on “Test account,” you see an example of a boiler connected to our online system. And when you click on “Map” you see all our boilers connected online throughout Europe.

RT10 Universal Room Thermostat

RT 10 Universal room thermostat is designed to control and monitor room temperature, central heating temperature and DHW temperature. The device contains a weekly heating programme and works with four mixing valves (using other equipment) and includes a parental lock to protect against unwanted setting changes.

The thermostat has an easy-to-read large graphic colour touch screen that makes it easy to read and change thermostat parameters.

Furthermore, you can change the temperatures of both the boiler and, for example, individual heating circuit temperature, storage container, DHW tank and so on.

The package also includes a structure that facilitates wall mounting.

If the boiler is connected to the Internet, it’s also possible to remotely change the temperature in the building using a free application on your phone.

RT10 Thermostat

CS260 Wireless Module

The wireless module is an additional accessory to the RT10 room thermostat. Enables a wireless connection between the thermostat and boiler.

However, the wireless version needs mains power. Therefore, the thermostat is connected in the room to a 230V socket and from the thermostat, the signal is sent wirelessly to the boiler room, where it is processed by a receiver connected to the boiler.
