APPLICATIONS

• 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 3rd 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 test function
Enter the “Test” menu via the installer key. The Application test (APP test) is specific for each application. The test is split into steps to ensure that all components are installed correctly. Please follow the process

Test steps
Step 1:1 Go to mixing shunt control valve actuator, and verify that the valve opens fully (up to 3 minutes opening time can be expected). After 5 minutes, the mixing shunt valve actuator will close again. During the 5 minute test period, the display on the Master Controller will also show the measured supply flow temperature in the display.

• 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

1. “SET 1” = Set supply flow temperature for change-over to heating [25-55°C]
2. “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.

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 integrated 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 3rd party GSM module. When global standby input is active, all rooms receive a 15 degree celcius setpoint.

Settings

1. “SET 1” = Set desired cooling hysterhesis for change-over [+2 to +4K]
2. “SET 2” = Set neutral time that must pass without active heating or cooling, before change-over can be activated [3-6 Hrs.]

• Excluding rooms from cooling: To exclude a room from cooling – typically in bathrooms where cooling would be uncomfortable – go to thermostat and set menu to . See Thermostat Installation Guide for further information.
• Choose reference room thermostat : To assign a thermostat as reference room thermostat, go to the desired reference room thermostat and in menu set to .
• When selected the thermostat will control when the system goes from heating mode to cooling mode based on the actual temperature in the room.
• It is only possible to have one reference thermostat per system and if more than one thermostats are assigned as reference, the last assigned will overwrite the previous reference room thermostats and cause these to revert to normal function

Application test function
Enter the “Test” menu via the installer key. The Application test (APP test) is specific for each application. The test is split into steps to ensure that all components are installed correctly. Please follow the process.

Test steps

1. Step 1:3 During the first minute of the test, the heat source is set to “heating mode” via “PWR1 output”. Check on heat source user interface that heating is active.
2. Step 2:3 During the second minute of the test, the heat source is set to “cooling mode” via “Relay output”. Check on heat source user interface that cooling is active
