The "External heating program changeover" function is connected via input
"aVD" in the power/pump module. You can select which heating circuits the
heating program changeover affects in coding address "91":
Heating program changeover
No changeover
Heating circuit without mixing valve
Heating circuit with mixing valve
Heating circuit without mixing valve and heating circuit
with mixing valve
You can select which direction the heating program changeover takes in
coding address "d5":
Heating program changeover
Changeover towards "Permanently reduced" or
"Permanent standby" mode (based on the selected setpoint)
Changeover towards "Constant heating mode"
The duration of the heating program changeover can be adjusted in coding
address "F2":
Heating program changeover
No changeover
Duration of the heating program changeover 1 to 12 hours
The heating program changeover stays enabled for as long as the contact
remains closed, but at least as long as the duration selected in coding address
"F2".
The "External blocking" function is connected via input "aVD" in the
power/pump module. In coding address "32", you can select the influence the
"External blocking" signal should have on the connected circulation pumps.
The "External heat demand" function is connected via input "aVD" in the
power/pump module. In coding address "34" you can select the influence the
"External heat demand" signal should have on the connected circulation pumps.
The minimum boiler water setpoint temperature in case of an external heat
demand is selected in coding address "9b".
