SETTING CENTRAL HEATING WATER TEMPERATURE
USING THE OUTDOOR TEMPERATURE SENSOR
Since an outdoor temperature sensor is installed, the sys-
tem automatically adjusts the temperature of the central
heating flow to bring room temperature rapidly to a level
determined on the basis of outdoor air temperature.
To increase or decrease room temperature with respect to
the automatic setting calculated by the BAG control card,
turn the trimmers on the BAG card clockwise to increase
temperature or anti-clockwise to reduce it.
The available adjustment range is between -5 and +5
comfort levels. These are displayed on the REC 07/08
remote control (if present) or can be displayed on a
PC running dedicated software (see the “AUTOMATIC
TEMPERATURE CONTROL” section).
SETTING DOMESTIC HOT WATER TEMPERATURE
b
To set domestic hot water temperature, make
sure that no central heating zone is requesting
heat (the “Ot” message must not be visible on
the boiler display).
Make sure that there is no
bridge between terminals 23-24, 26-27 and 29-30.
Also make sure that no central heating zone
is requesting heat via Open Therm.
Under this
condition, the CH circuit (BAG) control card passes
control to the boiler control card, permitting adjust-
ment of DHW temperature (which is controlled by
the boiler control card).
To adjust the temperature of the domestic hot water
(bath, shower, washbasins, etc.), turn the knob with the
“
Å
” symbol. Turn the knob clockwise to increase water
temperature or anti-clockwise to reduce it. The digital
display reads out the new temperature setting as you turn
the knob. The adjustment range for DHW temperature is
between 35 and 60 °C. The display always reads out the
setting as you adjust water temperature, both for central
heating water and domestic hot water. Once you have set
the desired temperature, the setting is memorised after 4
seconds and the display once again reads out the actual
temperature of the CH flow or DHW as detected by the
temperature sensor.
b
If an REC 07/08 remote control is installed, DHW
temperature MUST be adjusted from the remote
control (see the specific instructions provided
with the remote control).
