DBR Operation
Mode
Dynamic Control (Recommended)
When Dynamic Control is selected, the on/o cycles are deter-
mined by the heat demand in the rooms and the temperature
of the return pipe into the boiler to optimize energy savings.
Recommended in systems with bypass in heating circuit, such
as AVDO valve. It is possible to adjust the Setpoint Limits in
this mode. Dynamic Control only possible to select with ESM-
11 sensor mounted on return pipe
On when Heat Demand
The boiler is only ON when there is heat demand from a
reference room in the system. Recommended for modu-
lating boilers and non-condensing boilers.
TPI (Time Proportional Interval)
A duty cycle is calculated and used to control the boiler.
Select ‘Cycle Time’ in Settings.
