Moreover, a minimum On time of 3 minutes before switching off will be ensured.
In case of recalling of PAC-IF card step 0 (switch OFF), it will also be necessary to wait a minimum switch off time (maintaining of step 0).
The activation of these time delays will be notified on PGD1 in the following way:
•
No delay.
•
Short delay (5 minutes).
•
Long delay (10 minutes).
•
Hot/cold mode change (2 minutes)
•
Minimum OFF time.
In addition to the compliance with the above time scales, the switching on of the PAC-IF card will also be subjected to the consent from the s-Mext unit to carry out the
adjustment (example: Unit ON from keypad/KIPLink), and to the absence of any critical/blocking alarms that would cause the switching off of the s-Mext unit.
ATTENTION
In case of blocking alarm from a PAC-IF card, step 0 is forced until the normal operating conditions are reinstated. This forcing is
necessary in order to reset the alarm, but causes the switching off of all PAC-IF cards.
