Default Integral action time TN is fix to 45 minutes.
When the thermostat is set with control sequence “H/C ceiling with 6-port control
ball valve”; only the Y10 output can be used to control the 6-port control ball valve.
Output voltage range of Y10 can be configured via P201. For details, see Overview
[➙ 75].
P201 = 6 6-port valve (DC 0…10 V control signal)
P201 = 7 6-port valve (DC 2… 10 V control signal)
P201 = 8 Inverse signal, 6-port valve (DC 10… 0 V control signal)
P201 = 9 Inverse signal, 6-port valve (DC 10… 2 V control signal)
When the thermostat is set with control sequence “H/C ceiling with 6-port control
ball valve”, the fan control will be set as disable and cannot be changed.
The parameter P350 (Fan control) is set to 0 and cannot be change.
