Cost-effective Danfoss Icon set tailored for properties with 4 heated rooms (zones). Room thermostats measure the temperature of individual rooms and send data to the control regulator. The temperature of each room (zone) is adjusted separately according to the individually set temperature. You can view the current room temperature on the thermostat display. The temperature can be set either manually or remotely via a mobile app. You can easily download the Danfoss Icon app from Google Play or from the App Store.

This set includes:

• 1x 088U2100 Danfoss Icon2 Control Regulator, basic version for two-pipe systems
• 1x 014G2400 Danfoss Ally Gateway Central Unit
• 4x 088U2128 Danfoss Icon2 24V Wired Room Thermostat for Surface Mounting
• 4x 088H3142 Danfoss TWA-K 230 V NC Thermoelectric Actuator

Master Controller 24V

The central control unit monitors the temperature in each room using connected thermostats and checks whether heating is needed or should be turned off. It regulates underfloor heating and ensures balanced heating of all rooms regardless of their size. This prevents smaller rooms from being prioritised over larger ones, as happens in some systems.

Ally Gateway - Zigbee Module

The Ally Gateway connects the Danfoss Icon control regulator to the wifi network and allows remote communication with the mobile app. Temperature settings or changes to the heating schedule can thus be made from anywhere.

Room Thermostat

A thermostat with a display that shows the current room temperature. All control and settings of the thermostat are done via the display, which is activated by a light swipe of the finger. Thanks to its design, the thermostat blends seamlessly with any interior and does not disrupt its concept. The thermostat is connected to the control regulator via a wire. It is installed directly on the wall in the room on the plaster.

Thermoelectric Actuator

An actuator connectable to valves with an M30x1.5 connection. It visually indicates its current position (open/closed). In the event of a power failure, the actuator automatically closes the valve.

If you need a thermoelectric actuator with a different type of connection, e.g., Danfoss RA, etc., please email us with specific requirements at hurda@bola.cz. We will be happy to create an individual offer for the entire Danfoss Icon set.

Why choose Danfoss Icon for underfloor heating control?

The Danfoss Icon range meets all the requirements for underfloor heating control. It offers high variability and adapts to household needs. It includes four types of thermostats with various advanced features and control regulators that monitor the temperature throughout the property. They are available in both wired and wireless versions with the option to connect everything to a mobile app and control heating remotely.

The Danfoss Icon system knows the approximate size of heated rooms, which allows it to heat all rooms evenly. Water in the pipes tends to flow the path of least resistance, choosing shorter loops under smaller rooms. This creates an imbalance where smaller rooms receive more heating water and are heated faster than larger rooms, which receive less water. Danfoss Icon solves this problem by fairly distributing heat according to room sizes.

They are designed in a modern style that blends seamlessly with any interior. For thermostats installed in the wall, it is possible to change their frame freely and choose one that best suits the room.

The Icon system is fully compatible with the Ally radiator system. Mixed heating is therefore not a problem at all, the system temperature is controlled either by the Ally or Icon system, and it is entirely up to the user which one they choose as the master. Additionally, Danfoss Ally can be connected to voice assistants such as Alexa, Siri, and Google Home.
