FHM-CN Mixing Shunt

Application

Ordering

The Danfoss mixing shunts are used for regulation of flow and supply temperature in hydronic floor heating systems. The compact, flexible design allows mounting the mixing shunt directly to the manifold on both left and right side, with the primary pipe connection from the side or below.

The FHM-CN mixing shunts can be mounted directly to the Danfoss manifold system without the use of special equipment.

By using Danfoss floor heating controls all expectations of a professional floor heating system are fullfilled.

A self-acting proportional regulator is used to regulate the supply temperature. The regulator ensures that the desired supply temperature to the underfloor heating system always remains constant.

Fig. 1: Electrical connection

The FH-ST safety thermostat is fixed on the tube and protects floor and system against too high temperatures, especially important for wooden floors. The FH-ST thermostat switches off the power supply of the floor heating base unit, when the temperature reaches 55 °C. By switching off the power supply of the floor heating base unit, the actuators (NC) will close automatically and the floor heating system is protected. The

FH-TC can also be connected to a pump or a zone valve.

Note!

The electrical installation must be carried out by an authorized installer only (230 V DC).
