Control Functions
External heating program changeover
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 Coding
No changeover 91:0
Heating circuit without mixing valve
Heating circuit with mixing valve
Heating circuit without mixing valve and heating circuit
with mixing valve
91:1
91:2
91:3
You can select which direction the heating program changeover takes in
coding address ”d5”:
Heating program changeover Coding
Changeover towards ”Permanently reduced” or ”Permanent
standby” mode (based on the selected setpoint)
d5:0
Changeover towards ”Constant heating mode” d5:1
The duration of the heating program changeover can be adjusted in coding
address ”F2”:
Heating program changeover Coding
No changeover F2:0
Duration of the heating program changeover 1 to 12 hours F2:1 to F2:12
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”.
External blocking
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.
External heat demand
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”.
