▪ The zone with the highest leaving water temperature (in heating) is called the

additional leaving water temperature zone.

Remark: In practice, the main leaving water temperature zone consists of the

higher load heat emitters and a mixing station is installed to achieve the desired

leaving water temperature.

# Code Description

[A.2.1.9] [F-0D] Pump operation mode

▪ 0 (Continuous)

▪ 1 (Sample)

▪ 2 (Request)

When the space heating/cooling control is OFF by the user interface, the pump is

always OFF. When the space heating/cooling control is ON, you can select the

desired pump operation mode (only applicable during space heating/cooling).

Continuous:

Continuous pump operation, regardless of thermo ON or OFF condition.

Remark: Continuous pump operation requires more energy than sample or

request pump operation.

a Space heating/cooling control (user interface)

b OFF

c ON

d Pump operation

Sample:

The pump is ON when there is a heating or cooling demand as the leaving water

temperature has not reached the desired temperature yet. When thermo OFF

condition occurs, the pump runs every 5minutes to check the water temperature

and demand heating or cooling if necessary.

Remark: Sample is NOT available in external room thermostat control or room

thermostat control.
