Control operating mode
Depending on the control variance (difference between set-point/actual values) and
the parameters set, the controller will work in heating or cooling mode. A configuration
parameter (register 101) can also be used to make ventilation independent from the
mode. This allows one to specify e.g. that in winter, only heating is possible, and in
summer, only cooling (see Config FBox hardware, ventilation mode).
Limits for heating and cooling
The maximum output values for cooling (CoolY) and heating (HeatY) can be limited.
The initial value can be set in the Config FBox
(register 140 for cooling and register 141 for heating)
Range: 0…100 %, default: 100
The current value is set in the Room FBox
(register 142 for cooling and register 143 for heating)
Range: 0…100 %, default: 100
