Radiator Thermostat RAS-D2Combi

BI-DIRECTIONAL VALVE WITH FLOW-SELECTABLE FEATURE

Close all radiator valves by turning

the valve cover cap clockwise.

Leave system to cool.

Start boiler/heating.

Open one valve and determine

flow direction. Which pipe heats

first?

Remove cap and turn setting ring

according to the drawings - the

setting ring is turned by hand only.

Repeat step 3 and 4 until all valves have

been set correctly. Sensor may now be

fitted or the valve cap temporarily refitted.

Installation of valve

The valve is a bi-directional valve * and can be

installed horizontally or vertically in either the flow or

return pipe.

A built in flow direction selection feature can be used

to eliminate the risk of water hammer.

We recommend using a flat faced adjustable

spanner and a soft cloth to protect the chrome

surfaces when tightening up the connections.

Troubleshooting

In the unlikely event of water hammer being encoun-

tered turn the setting ring (see diagram 4) to the

other setting.

Alternatively if commissioning the whole system,

establish the flow direction through each valve using

the diagrams below.

If the flow direction needs to be changed there is no

need to remove the valve, simply turn the setting ring.

* Maximum pressure drop should not exceed 0.45 bar Danfoss DKCD 03/2005VIAQA102

Removing the Sensor

Loosen the Allen screw (3).

The sensor can now be separated from the valve.

Setting the desired room temperatures

The desired room temperature is set by turning

the head. The temperatures obtained are ap-

proximately:

Do not cover the thermostat

The thermostat opens and closes as determined

by the temperature around it. Therefore the sen-

sor must never be hidden behind thick curtains,

furniture, etc. Alternatively a thermostat with

remote sensor should be used.

in codes: Code no’s 013G6016 and 013G6017

decoration purposes.
