| The FED sensors are used in applications in which a cooling and a heating circuit is to be controlled by one controller. FED sensors can be applied to chilled ceilings, fancoils and induction units. |

| The controllers are installed in rooms which have surplus heat due to internal or external heat sources. FEK can be used for chilled ceilings, fan-coils and induction units. |

Together with the Danfoss self-acting and electronic controllers the RA-C valves make up a perfect combination for control of cooling and heating circuits.
The RA-C valves have four possible pre-settings to ensure correct water flow.
RA-C valves are made of dezincification-resistant brass, specific for cooling systems. The valves are designed with external threads, which will make the installation easier. |

| TWA actuators are used to electically activate valves on hot water heating systems, where slow opening and closing is desirable to eliminate water hammer associated with quick acting valves. TWA is a low voltage (24V), low power consumption actuator equipped with a visual indicator to show the open or closed position of the valve. TWA actuators can be selected to create either a normally open or a normally closed control. Maximum ambient temperature is 140F (60C). |

| The modulated thermal actuator ABNM is used in direct digital controlled (DDC) systems with 0- 10 V DC control voltage. ABNM apply both in heating and cooling systems. |
