ROOM TEMPERATURE SENSOR

with fan speed control switches

Specification No. 337-X-XXX*

The DRT Room Temperature Sensor incorporating fan speed control

switches is used in conjunction with the CZU temperature controller.

This system is used for the control of temperature zones of buildings,

such as hotel bedrooms or individual offices, which are air conditioned

by means of fan coil units. The room occupant is provided with local

adjustment of room temperature and also fan speed (ON/OFF or OFF,

1, 2 and 3), for optimum comfort settings.

The instrument can, alternatively, be applied as a remote temperature

setting unit, in conjunction with a DDU temperature sensor located in

the fan coil unit return air space, for example.

Alternative models are available to suit units with either single-speed

or 3-speed fans.

* For the full specification number replace the 4Xs with the appropriate figures

from the TYPE column in the table overleaf.
