Application 0001: 2-pipe system, ﬁxed supply temperature, electronically

controlled.

Optional: Global standby.

Application description

Floor heating system with electronic supply temperature control. The supply temperature is set to a ﬁxed

value.

The system uses a PT1000 sensor to detect and control the supply temperature and is also used to ensure

that the temperature does not exceed the max. allowed temperature. If connected, the system will control

the circulation pump and the heat demand signal for e.g. a boiler or heat pump. The pump and heat

demand signal will be on when minimum 1 circuit has a heat demand. Output 1 must be used for TWA on

mixing shunt.

The Global standby is a potential free input that can be used to remotely put the system in Global away

mode e.g. via an external 3

rd

party GSM module. When global standby input is active, all rooms receive a 15

degree celcius setpoint.

Settings

“SET 1” = Set desired supply ﬂow temperature [25-70°C]

“SET 2” = Set desired safety cut-oﬀ temperature [30-75°C]

Note: temperature must be higher than ﬂow temperature.

Application 0003: 2-pipe system with automatic changeover for cooling based

on supply temperature.

Optional: Dewpoint sensor (recommended), Global standby, Circulation pump and heat demand

signal.

Application description

Floor heating system with automatic changeover for cooling based on supply temperature input.

The supply temperature is monitered using a PT1000 sensor. Based on the measurement, the system

switches to heating or cooling. If connected, the system will control the circulation pump which will be

turned on when minimum 1 room has a heat or cooling demand.

The heat signal for e.g. a boiler or heat pump is only activated when the system is in heating mode and

minimum 1 room has a heat demand. For cooling applications it is always recommended to have a dew

point sensor installed in the system to prevent moisture damage to ﬂoor and installations in cases where

the relative humidty exceeds dew point.

The Global standby is a potential free input that can be used to remotely put the system in Global away

mode e.g. via an external 3rd party GSM module. When global standby input is active, all rooms receive a 15

degree celcius setpoint.

Settings

“SET 1” = Set supply ﬂow temperature for change-over to heating [25-55°C]

“SET 2” = Set supply ﬂow temperature for change-over to cooling [15-25°C]

Note: temperature cannot be set higher than 2°C lower than heating change-over temperature.

Optional: Dewpoint sensor (recommended), Circulation pump and heat demand signal.

Application description

Floor heating system with automatic changeover for cooling controlled by heat source e.g. heat pump.

The heat pump provides the cooling signal to the Danfoss Icon™ Master, when the heat pump goes into

cooling mode thus activating cooling mode. If connected, the system will control the circulation pump and

it will be turned on when minimum 1 room has a heat or cooling demand.

The heat signal for e.g. a boiler or heat pump is only activated when the system is in heating mode and

minimum 1 room has a heat demand. For cooling applications it is always recommended to have a dew

point sensor installed in the system to prevent moisture damage to ﬂoor and installations in cases where

the relative humidty exceeds dew point.

Application 0005: 2 pipe system with hybrid Air/water heat pump with inte-

grated condensing boiler (example: Itho Cool Cube). Change over ordered from

reference room thermostat.

Optional: Dewpoint sensor (recommended) and Global standby.

Application description

Floor heating system with cooling done via e.g. Coolcube used as heating and cooling source.

The Icon™ system controls the heat and cooling demand by activating the corrosponding relay (PWR1

and potential free relay). For cooling applications it is always recommended to have a dew point sensor

installed in the system to prevent moisture damage to ﬂoor and installations in cases where the relative

humidty exceeds dew point. Four conditions must be true before cooling in a room is allowed:

• Reference room temperature must exceed the room setpoint + cooling hysterhesis.

• No room has called for heating within neutral time.

• The dew point sensor must not be active / no condensation risk present.

• The room thermostat must be enabled for cooling (default = enabled).

The Global standby is a potential free input that can be used to remotely put the system in Global away

mode e.g. via an external 3

rd

party GSM module. When global standby input is active, all rooms receive a 15

degree celcius setpoint.

Settings
