all boilers on the peer-to-peer network is adjusted above the DHWP
Setpoint.
Local setpoint and modulation rate is used. Modbus and remote
input (C+,C-) are ignored.
Remote Input (C+, C-) is used as the temperature setpoint.
Parameter 22 & 23 may be used to adjust the signal range.
RS485 Modbus (40006) is used as the temperature setpoint.
Remote Input (C+, C-) is used as the modulation rate.
RS485 Modbus (40006) is used as the modulation rate.
Remote Sensor Input (R+.R-) is ignored.
Remote Sensor Input (R+,R-) is used for display only.
Remote Sensor Input (R+,R-) is compared with the temperature
setpoint to establish a modulation rate.
