DRS1 DIGITAL ROOM THERMOSTAT

Adjust the Backlight

External Sensor Configuration

Connections are available to fit an external sensor

(code: SP-03) if required. The thermostat is supplied in a

floor temperature limiting mode. This means that if the

floor reaches 27°C, regardless of the room temperature,

the thermostat will stop sending a demand signal to the

wiring center thus ensuring the flow of water to the UFH

circuit is stopped and the floor temperature, can no longer

increase. If this happens, the heat demand indicator on the

left-hand side of the LED will flash.

Hold both the up and down buttons together for 10

seconds until number 5 appears on the screen.

Use the up and down buttons to select the

preferred level of backlight (L0 is off and L4 is the

brightest available).

Wait for the thermostat to revert to normal operation

following selection.

In some circumstances, remote control of the external

sensor is required. For example, when heating a

bathroom, the thermostat should be mounted outside the

heated area and an external sensor should be ran into the

bathroom. The external sensor can be fitted in the floor to

control the floor surface temperature, or alternatively, it

can be mounted within a sensor housing to allow remote

control over the bathrooms air temperature. When in this

mode, if an external sensor isn't fitted, the thermostats

screen will display the error code 'E1'.

To change between the two modes of operation, follow

the process below:

The thermostat has a reset button situated on the

bottom right of the thermostat. Hold both the up and

down buttons and using a paperclip (or similar), press

the reset button. Continue to hold the two buttons until

'FL' appears on the screen.

Use the up and down buttons to switch between the

two modes.

Wait for the thermostat to revert to normal operation

following selection.
