=0 or 1) without mid-season mode (
013
=0)
The “ COOL” icon is displayed to indicate that cooling mode is active.

If the operating temperature rises above WCS , the modulating valve starts to open. The icon is displayed.
The valve can be controlled with PI action if the integral time

The icon switches off if the valve closes.

: hysteresis for on/off output.
If Treg > ( WCS +
122
), the valve is activated. The icon is displayed.
If Treg <= WCS, the valve is disabled and the icon is switched off.
Note: In case the winter compensation is used (
130
=1 or 3), you must pair an external sensor with an analogue input
