5.4 - OPERATING MODE
5.5 - STARTING
The unit is factory configured for remote control by contact (see other possibilities in paragraph 4.3.3).
• Initial condition:
- machine hydraulically and electrically connected ready to operate,
- the remote stand-by contact is open (= stand-by).
•
Turn the installation on:
- the display comes on and shows the water temperature (read by the control probe
SD1). The mode indicator lamps (4)
and (
5) flash to signal remote stand-by
,
- the unit's circulating pump starts.
•
To start the unit:
- close the remote stand-by contact (not supplied) if connected (see paragraph 4.3.3),
- the cooling indicator (4) comes on,
- the compressor "ON" indicator light (
6) comes on if necessary (see diagram paragraph 5.4). If the light flashes, it means
that the compressor is starting required but that a safety delay is in progress. This light stays on when the compressor
has started.
•
To stop the unit:
- open the remote stand-by contact,
- the compressor operation indicator lamp (
6) goes out and the operating mode indicator lamps (4) and (5) flash,
- the unit's circulating pump remains in operation.
•
Complete stop:
- the unit can be completely stopped with the circulating pump shut-down by pressing
and holding the
ON/OFF button (1) for 2 seconds. The display unit goes blank, only the
decimal indicator lamp (9) remains illuminated. This shut-down takes priority.
Note:
Shut-down of the circulating pump is delayed 1 minute after the compressor stops.
