Description

[9.3.5]

▪ The  capacity  difference  between  the

second  and  first  step  of  the  backup
heater  at  nominal  voltage.  Nominal
value  depends  on  backup  heater
configuration.

Configuration wizard: Main zone

The most important settings for the main leaving water zone can be
set here.

Emitter type

Depending on the system water volume and the heater emitter type
of  the  main  zone,  heating  up  or  cooling  down  the  main  zone  can
take longer. The setting 

Emitter  type

 can compensate for a slow

or  a  quick  heating/cooling  system  during  the  heat  up/cool  down
cycle. The target delta T for the main zone depends on this setting.

In room thermostat control, 

Emitter  type

 influences the maximum

modulation  of  the  desired  leaving  water  temperature,  and  the
possibility  for  usage  of  the  automatic  cooling/heating  changeover
based on the indoor ambient temperature.

It is important to set 

Emitter type

 correctly and in accordance with

your system layout.

The setting of the emitter type has an influence on the space heating
setpoint range and the target delta T in heating as follows:

NOTICE

For  radiators,  the  average  emitter  temperature  will  be
lower  compared  to  underfloor  heating,  due  to  the  fixed
delta T of 10°C. To compensate, you can:

▪ Increase  the  weather  dependent  curve  desired

temperatures [2.5].

▪ Enable  leaving  water  temperature  modulation  and

increase the maximum modulation [2.C].

Control

Defines  how  the  operation  of  the  unit  is  controlled.  There  are  3
possibilities:

Control

In this 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
thermostat

Unit operation is decided by the external
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

In 

Fixed

  mode,  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.

▪ 2: 

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 has the possibility to 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.

▪ In 

Weather  dependent

  LWT  setpoint  mode,  the  scheduled

actions consist of desired shift actions, either preset or custom.
