Hydraulic and control diagram of the 6-port control ball valve
W Room temperature setpoint
YH Control command "Valve" (heating)
YC Control command "Valve" (cooling)
Kv Vale flow
T[℃] Room temperature
Default integral action time TN is set to 45 minutes.
If the thermostat is set to control sequence "H/C ceiling with 6-port control ball
valve", only output Y10 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
[➙ 91].
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)
If the thermostat is set to control sequence "H/C ceiling with 6-port control ball
valve", fan control is set to disable and cannot be changed.
Parameter P350 (Fan control) is set to 0 and cannot be changed.
