Function

The JRG LegioTherm 2T circulation valve is used wherever a controlled thermal disinfection of a hot water system is required in addition to its function as a Controller (such as in nursing homes, hospitals, etc.).
The JRG LegioTherm 2T circulation valve allows for two calibration temperatures (normal operation / thermal disinfection).
The JRG LegioTherm 2T circulation valve regulates the flow rate by permanently reading the water temperature with the help of an immersed temperature sensor.
The measured values are processed by the Controller. If a deviation from nominal temperature is detected, the circulation valve regulates the flow rate by opening or closing the valve until the set-point temperature is reached. This is done by means of an actuator.

• Connection: male thread (for union connection with flat gasket)

Installation

Wiring Master and valves

The connection cables contain four wires, two for power supply and two for signal transmission. Both cable ends are equipped with the same female connectors and feature an anti-twist design. The M12 knurled coupling nuts provide a reliable grip even in harsh environments.

Note:
Unapproved components may cause malfunctions!
All components must be connected in series (one after the other, with each other) .
A parallel or star-shaped wiring of the components leads to malfunctions in the BUS communication. Components and cables must not be modified. Never disconnect the cable from electricity under power.

Connecting the Master

Connect one of the plugs (11) of the connection cable to one of the two M12 sockets (12) on the Master and screw on the knurled coupling nut. Both connections of the Master can be used at the same time.

Connecting the valve

Connect the other plug (11) of the connection cable with one of the two M12 sockets (6) of the valve and secure with the knurled coupling nut. It does not matter which M12 socket is used.
Connecting further valves:
Connect one of the plugs of the next connection cable to the second M12 socket (6) on the valve and secure with knurled coupling nut, etc.

Note:
Risk of malfunctions due to faulty installation!
If the knurled coupling nut is not tightened properly, the plug connection may get loose over time. This may lead to a loss of functionality!
Make sure that all knurled coupling nuts of the connection cables are tightened!
Laying the cables:
The cables may be mounted directly on the circulation line or if need be on the outside of the insulation. Use temperature-resistant cable ties (up to 90 °C).

Installing a Power box
For cable lengths over 300 m, a Power box (14) must be installed between two connection cables.

Installing a JRG LegioTherm 2T
The JRG LegioTherm 2T can be mounted in any position. The valve must be accessible for inspections and revisions. We recommend to install shut-off valves JRG Code 8339 before and after the Controller. To prevent the JRG LegioTherm 2T circulation valve from being flowed against the desired flow direction, it is advisable to install suitable check valves. We recommend using JRG LegioTherm insulation to reduce heat emission.

Note:
For revision purposes there must be a clearance of 3 cm between the Controller and the nearest surface.

Note:
After installation, remove the label (5) with the valve serial number from the valve and stick it to the installation diagram.
In doing so, the valve can be easily located later on. The serial number is also displayed in the Master.
An individual designation can be additionally defined in the Master.

Flushing
Before installing the JRG LegioTherm 2T circulation valve, all pipes have to be flushed thoroughly.
Gaskets
Only AFM 34 gaskets are to be used. AFM 34 gaskets must not be oiled or greased.
Soldering
When using soldered joints, the JRG LegioTherm 2T valve must not be installed during soldering (possible damage due to overheating) .
