Internal exchanger electric heaters (folder PAr/HI)
Parameters for internal circuit exchanger heaters can be viewed and configured in folder HI: Internal circuit electric heater parameters (see User
Interface and Parameters chapters).
Antifreeze/integrated use heaters should be connected to a relay output (°) DO1..D04, D06 (see).
•
They are active only when the relative parameter enabling them HI00, HI02=1 (see table)
•
In Std-by the antifreeze heaters can be enabled by configuring HI01=1 (see table)
•
In defrost, the antifreeze heaters can be enabled by configuring HI03=1 (see table)
(°) When configuring the machine with two internal exchanger electric heaters, configure two outputs:
•
one output as internal exchanger heater 1
•
one output as internal exchanger heater 2
Two internal exchanger electric heaters can be configured in parameter HI04
