DKCD

Radiator thermostats for one-pipe and two-pipe systems

Built-in sensors

are best fitted horizontally so that the ambient air can

pass freely over the sensor without being affected by

heat from valve and possibly surface pipes.

Remote sensors

should be used when:

- curtains cover the sensor

- or the sensor is affected by surface pipes.

- It is necessary to mount the sensor in the vertical

position because of adjacent obstructions and the

valve body is flow mounted.

The remote sensor must be mounted on the wall, away

from curtains, or on the skirting board beneath the

radiator if free of surface pipes. All remote sensors are

now supplied with ultra-thin capillary. Simply pull out

the length required (2m max.) and fix using clips

provided.

Remote temperature adjuster

is ideal for use when the valve is positioned inaccessible

to the user. The temperature adjuster should be

mounted 1.5m above the floor.

IMPORTANT

Do not use RA 2000 sensors with RA-FR reversible

valve bodies.

Should the valve body gland seal shows signs of

weeping, the gland seal can be renewed in a few

minutes with the system in operation.

Order gland seal 013U0070 for RAVL and RAV

valves. 013G0290 for RA-FN and RA-G. (Sold in

packs of 10 units, complete with instructions).
