CHRONOS Chronothermostat User Manual
Emergency regulation (for heating mode only)
The chronothermostat performs a regulation of emergency if an error occurs during the
reading of the probe or in case of time loss.
In case of probe error , if the antifreeze function is not deactivated, the
chronothermostat activates the load for 10 minutes every 4 hours. The display shows
the writing
(UU
on field (7) .
In case of time loss (because of depleted batteries or blackout of a duration higher
than the charge reserve) the chronothermostat restarts from the off mode, adjusting
on the basis of the antifreeze temperature, if it hasn’t been deactivated before. Reset
date/ time to go back to the normal operation (programs modifications and settings
remain memorized).
TIMINGS: WHAT THEY ARE
Timings allow to maintain the current operation (automatic, manual, off) for a certain
period (times or days) and once passed the chronothermostat changes the operating
mode, as explained below.
The timed operations are the following:
Timed automatic
If in automatic status you set a timing, such off status will be maintained until the end
of the timing; operation will then switched to off mode.
Timed manual
If in manual status you set a timing, such off status will be maintained until the end of
the timing; operation will then switched to automatic mode.
