Fan speed is linear reduced from forced to normal when outdoor temperature decreases from “Outd.

Temp. fan forced” to “Outd. Temp. fan normal”.

Fans will gain forced speed immediately at cooling sequence even if climate controller hasn’t achieved

forced speed.

By input for external timer the fans will run on forced speed.

2.9 Control sequence

Cooler, heat recovery (VVX) and heater will in sequence control the temperature. At warming demand

the output to cooler decreases, than VVX starts (with different run/stop intervals out of needs at digital

VVX or with an increasing output signal at analogue VVX) and finally increased output signal to

heater.

The sequence is opposite at cooling request.
