OPERATING YOUR DT92E
Switching Off
Pressing the off/standby button
will switch the DT92E into off/
standby mode. The symbol
will show in the display, and the
unit will control at the frost protect
setpoint, as set at the ST9420C.
To switch back on, simply press
the
button again.
Display Updates
To conserve battery power, DT92E only communi-
cates with ST9420C at regular intervals or when you
press a button. This means there can be up to a
few minutes delay between an action initiated on
ST9420C and the DT92E display being updated.
If you press a button on DT92E it may take a few
seconds for ST9420C to respond. DT92E will
indicate it is waiting for information by displaying the
hourglass symbol and dashes as shown.
Heating Indicator
The flame symbol indicates that the
boiler is on for heating. The flame will
disappear when there is no heating
demand.
Frost Protection
The frost symbol will be displayed if the room
temperature goes below the frost setting. The flame
will also be displayed to indicate when the boiler has
been switched on.
