In the presence of free cooling conditions:
if Treg > WCS the on/off damper is activated.
if Treg <= (WCS -
178
) the damper is deactivated.
if Treg > (WCS +
122
) the cooling valve is activated.
if Treg <= (WCS +

/2) the cooling valve is deactivated.
Operation with modulating damper and on/off cooling valve:

: hysteresis for on/off output
solid curve: modulating damper output

If temperature of regulation sensor rises above WCS, the modulating damper in the presence of free cooling conditions goes
from the minimum opening position (parameter
164
) to the maximum opening position (parameter
165
) in the band defined by
