CHRONOS KEY Programmable Thermostat User Manual
Emergency regulation (only for heating mode only)
The instrument performs an emergency regulation if an error occurs during the reading
of the probe or in case of loosing the hour data.
In case of probe error , if the antifreeze function is not deactivated, the instrument
activates the load for 10 minutes every 4 hours. The display shows the writing
Err
on
field
(7)
.
In case of
loosing time data
(because of depleted batteries or a blackout is longer
than the charge reserve) the instrument restarts from the off mode, adjusting the
temperature according to the antifreeze temperature, if it has not been deactivated
before. Set again date/time to go back to the normal operation (programs modifications
and settings are stored).
TIMINGS: WHAT THEY ARE
Timings allow to maintain the current operation (automatic, manual, off) for a certain
period of time (hours or days) and after the programmable thermostat changes the
operating mode, as explained below.
The timed operations are the following:
Timed automatic mode
When a timing is set in automatic mode, the status is maintained until the end of the
timing. After that, the operation will switch to OFF mode.
Timed manual mode
When a timing is set in manual mode, the status is maintained until the end of the
timing. After that, the operation will switch to automatic mode.
