Modulating direct expansion coil

To use the modulating regulation, set parameter

PG07=3

COOLING

HEATING

By setting parameter PH59 of the polarity of the analog output of the direct expansion battery to Custom, it is possible to manage the direct expansion battery accord-

ing to the logic defined by the graphs below. To use this function correctly, the following parameters must also be set:

PE16:

Minimum output value in cooling for custom regulation

PE17:

Maximum output value in cooling for custom regulation

PE18:

Minimum output value in heating for custom regulation

PE19:

Maximum output value in heating for custom regulation
