Leaving Water Temperature Control - Rotex RKHBRD011AAV1 Manual De Operación

Selecting space heating operation
Use the y button to switch ON/OFF space heating (h).

Icon h appears on the display as well as the corresponding
water temperature set point.
The operation LED 0 lights up.
Use the bi and bj buttons to set the desired room

temperature.
Temperature range for heating: 16°C~32°C (room temperature)
In order to avoid overheating, space heating is not operable
when the outdoor ambient temperature rises above a certain
temperature (see operation range).
Refer to "Programming and consulting the schedule timer" on
page 11 for setup of the schedule timer function.
Use the ébi and ébj buttons to select the leaving

water temperature which you want to be used to heat up your
system (for detailed information see "Leaving water temperature
control" on page 5).
Automatic setback function
Setback function provides the possibility to lower the room
temperature. The setback function can for instance be activated
during the night because the temperature demands during night and
day are not the same.
Remark that the b icon will be flashing during
NOTE
setback operation.
By default the setback function is enabled.
The setback function can be combined with the
automatic weather dependent set point operation.
Setback function is an automatic daily scheduled
function.
The setback function is configured through field settings. Refer to the
chapter "Field settings" on page 14 for a detailed description how to
set one or more field settings.

NOTE While room temperature setback function is active,
leaving water setback operation is also performed (see
"Leaving water temperature control" on page 5).
Pay attention not to set the setback value too low,
especially during colder periods (e.g. winter time). It is
possible that the room temperature can not be reached (or
it will take a much longer time) because of the big
temperature difference.

Leaving water temperature control

In this mode, heating will be activated as required by the water
temperature set point. The set point can be set manually, through the
schedule timer or weather dependent (automatic).
Selecting space heating operation
1 Use the y button to switch ON/OFF space heating (h).
Icon h appears on the display as well as the corresponding
water temperature set point.
The operation LED 0 lights up.
2 Use the é bi and ébj buttons to set the desired leaving
water temperature.
Temperature range for heating: 25°C~80°C (leaving water
temperature)
In order to avoid overheating, space heating is not operable
when the outdoor ambient temperature rises above a certain
temperature (see operation range).
Refer to "Remote controller schedule timer" for setup of the schedule
timer function.
NOTE When an external room thermostat is installed,
the thermo ON/OFF is determined by the external
room thermostat. The remote controller is than
operated in the leaving control mode and is not
functioning as a room thermostat.
The remote controller ON/OFF status always has
priority over the external room thermostat!
Selecting weather dependent set point operation
When weather dependent operation is active, the leaving water
temperature is determined automatically depending on the outdoor
temperature: colder outdoor temperatures will result in warmer water
and vice versa. The unit has a floating set point. Activating this
operation will result in a lower power consumption than use with a
manually fixed leaving water set point.
During weather dependent operation, the user has the possibility to
shift up or down the target water temperature by a maximum of 5°C.
This shift value is the temperature difference between the
temperature set point calculated by the controller and the real set
point. E.g. a positive shift value means that the real temperature set
point will be higher than the calculated set point.
It is advised to use the weather dependent set point because it
adjusts the water temperature to the actual needs for space heating.
It will prevent the unit from switching too much between thermo ON
operation and thermo OFF operation when using the remote
controller room thermostat or external room thermostat.
NOTE During this operation, instead of showing the water
temperature set point, the controller shows the shift
value which can be set by the user.
1 Press the ba button 1 time to select weather dependent set
point operation (or 2 times when the remote controller room
thermostat function is used).
Icon a appears on the display as well as the shift value. The
shift value is not shown in case it is 0.
Use the ébi and ébj buttons to set the shift value.
2
Range for the shift value: –5°C to +5°C
Icon a will be displayed as long as the weather dependent set
point operation is enabled.
Press the ba button to deactivate weather dependent set point
3
operation.
The ébi and ébj buttons are used to set the leaving
water temperature.
