5.2.4 Time band schedule function (room thermostat)
It is possible to set a time schedule for heating function and for the storage
tank filling (is installed) from the boiler.
Whenever the heating system is managed by a room thermostat, and
therefore without any time schedule, it is possible to tie the heat requests
coming from the device to programmable time bands by setting the
parameter POR = 1 (see section "5.2.2 Configuration of the zone" ), in other
cases it is always enabled.
To access this function:
- select MENU on the main page of the REC10 and press "ok"

From this menu it is possible to access the display and adjustment of the
time schedule for the heating functions of the zone rather than for the
domestic storage tank. For each day of the week it is possible to set up to
4 bands, characterised by a starting time and an end time.
Note: for more details on the use of the programming timing see the USER
MANUAL of the REC10.

5.2.5 Setting the thermoregulation
Thermoregulation only works with the outdoor temperature sensor
connected and active only for the HEATING function; therefore, once
installed, connect the outdoor temperature sensor to the specific
connections on the boiler terminal board.
This enables the THERMOREGULATION function.
The temperature measured by the outdoor temperature sensor is displayed
on the initial page in the top right, alternating with the display of the time.
When thermoregulation is enabled (outdoor temperature sensor present),
the algorithm for automatically calculating the outlet setpoint depends on
the type of heat request.
In any case, the thermoregulation algorithm will not directly use the outdoor
temperature, but rather a calculated outdoor temperature that takes into
account the building's insulation: in buildings that are well insulated, the
outdoor temperature variations will have less impact than those that are
poorly insulated by comparison. Enabling THERMOREGULATION occurs
in the following way:
- access the technical parameters as explained in the section "4.1 Access
to the technical parameters"
- select THERMOREGULATION with the "up" and "down" keys,
confirming the selection.

Using the REC10 it is possible to set the value of the following parameters:
BUILDING TYPE
It is indicative of the frequency with which the value of the calculated
outdoor temperature for thermoregulation is updated, a low value for this
value will be used for buildings that have little insulation.
Setting range: [5min - 20min]
Factory setting: [5min]
REACTIVITY EXT SENSOR
It is an indication of the speed with which variations of the measured
outdoor temperature affect the calculated outdoor temperature value for
thermoregulation, low values indicate high speeds.
Setting range: [0 - 255]
Factory setting: [20]
At this point, to change the value of the previous parameters, proceed as
described below:
- access the technical parameters as explained in the section "4.1 Access
to the technical parameters"
- in sequence select THERMOREGULATION and TYPE OF BUILDING
rather than REACTIVITY EXT SENSOR with the "up" and "down" keys,
confirming the selection
- set the desired value with the "up" and "down" keys, confirming the
selection.
Note: The value of the calculated outdoor temperature used by the
thermoregulation algorithm is displayed in the INFO menu under T EXT
FOR THERMOREG.
HEAT REQUEST FROM THERMOSTAT or POR (Programmable Timer)
In this case the outlet setpoint depends on the outdoor temperature for
obtaining a reference ambient temperature of 20°C. There are 2 parameters
that compete to calculate the output setpoint:
- slope of the compensation curve (KT)
- offset on the reference ambient temperature.
