Installation Guide
Application 0002: 2-pipe system with demand based supply temperature
control.
Optional: Global standby.
Application description
Floor heating system with electronic supply temperature control.
The demand based supply temperature is controlled depending on the heat demand from the rooms.
The system uses a PT1000 sensor to detect the supply temperature and is also used to ensure that the
temperature does not exceed the max. allowed temperature via a safety Tmax. 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
degree celcius setpoint.
Settings
"SET 1" = Set desired min. supply flow temperature [25-65°C]
"SET 2" = Set desired max. supply flow [30-70°C]
Note: temperature cannot be set less than 5°C higher than min. supply flow temperature.
"SET 3" = Set desired safety cut-off temperature [30-75°C]
Note: temperature must be higher than flow temperature.
