• 2-pipe COOLING control (
014
=0 or 1) with mid-season mode (
013
=1)
The “
COOL”
icon is displayed to indicate that cooling mode is active.
If there is a sudden reduction in the temperature during the summer, the mid-season mode can be used to warm up using
a heating element which can be modulating or on/off.

If Treg < WCS -
124
, the modulating electrical resistance is directed to heat, the
icon is displayed and remains displayed
until the temperature rises above this threshold.
The modulating resistance can be controlled with PI action if the integral heating time
115
does not equal 0 or, with
proportional action only if
115
=0.

the electrical resistance is disabled and the
icon is switched off.
Note: In case the winter compensation is used (
