NOTICE
Average
emitter
temperature
temperature – (Delta T)/2
This means that for a same leaving water temperature
setpoint, the average emitter temperature of radiators is
lower than that of underfloor heating because of a bigger
delta T.
Example radiators: 40–10/2=35°C
Example underfloor heating: 40–5/2=37.5°C
To compensate, you can:
▪ Increase
the
weather-dependent
temperatures [2.5].
▪ Enable leaving water temperature modulation and
increase the maximum modulation [2.C].
Control
Define how the operation of the unit is controlled.
Control
Leaving water
Unit operation is decided based on the leaving
water temperature regardless the actual room
temperature and/or heating or cooling demand
of the room.
External room
Unit operation is decided by the external
thermostat
thermostat or equivalent (e.g. heat pump
convector).
Room thermostat Unit operation is decided based on the ambient
temperature of the dedicated Human Comfort
Interface (BRC1HHDA used as room
thermostat).

Setpoint mode
Define the setpoint mode:
▪ Fixed: the desired leaving water temperature does not depend on
the outdoor ambient temperature.
▪ In WD heating, fixed cooling mode, the desired leaving water
temperature:
▪ depends on the outdoor ambient temperature for heating
▪ does NOT depend on the outdoor ambient temperature for
cooling
▪ In Weather
dependent mode, the desired leaving water
temperature depends on the outdoor ambient temperature.

Setpoint mode:
▪ Fixed
▪ WD heating, fixed cooling
▪ Weather dependent
When weather dependent operation is active, low outdoor
temperatures will result in warmer water and vice versa. During
weather dependent operation, the user can shift the water
temperature up or down by a maximum of 10°C.
Schedule
Indicates if the desired leaving water temperature is according to a
schedule. Influence of the LWT setpoint mode [2.4] is as follows:
▪ In Fixed LWT setpoint mode, the scheduled actions consist of
desired leaving water temperatures, either preset or custom.
