7) Battery replacement

A "flashing" battery low symbol will appear at the bottom left

of the display when the batteries start to approach the end of

their life. This indicates that they should be replaced within

the next month. Ultimately, the display will start flashing and

the thermostat will shut down until the batteries are replaced.

To replace the batteries, the following procedure should be

carried out.

1. Slacken the retaining screw on the unit and open by hing-

ing upwards the top edge.

2. Remove batteries and fit two new "AA" alkaline cells tak-

ing care to observe the correct battery polarities. Check

unit is functioning

3. Re-fit it to the plastic base and check that the RF link still

operates. This can be easily done by adjusting the re-

quested temperature under or over the level of the ambi-

ent temperature, in order to activate and disactivate sev-

eral times the boiler.
