General Guidelines
2.1 Heat supply
If the heating system has been optimized for constant set temperature around the clock, you may
need to adjust the settings when working with setback periods. When changing the temperature
from a low economy setting to a comfort temperature, the system must be able to supply enough
heat to raise the room temperature at least 1 °C per hour to perform well. Compared to a steady
temperature the heating system must typically be able to supply 25% more heat, but only for a
short period of time during heat up.

Increase valve presetting
Increase pump pressure
Increase water temperature
Note: Maximum acceptable presetting, water temperature and pump differential pressure settings are
different from system to system and depend on the application.
For radiator valves with pre-setting, balance the system
to allow for enough flow.
The supply line temperature at the radiator valves should be
above 40 °C to ensure optimal control.

Make sure that the supply water temperature and flow is
adequate to provide enough energy.
Increase the temperature or the pump level, if necessary.
