The room setpoint is obtained from the following tables :
HzA: Heating circuit of the LMU... (1 or 2) which is controlled by the main heating
circuit of the RU (RU1)
HzB: Heating circuit of the LMU... (1 or 2) which is controlled by the secondary heating
circuit of the RU (RU2)
Refer to «Configuration of the heating circuits».
Hz1 and Hz2 can also be simultaneously assigned to the RU1 or RU2 program.
