Using the REC10CH it is possible to set the value of the following parameters:
BUILDING TYPE: it is an indication of the frequency with which the value of the calculated
outdoor temperature for thermoregulation is updated, a low value will be used for buildings
that have little insulation.
Setting range: [5min - 20min]
Factory setting: [5min]
OUTDOOR REACTIVITY: it is an indication of the speed with which variations of the
outdoor temperature affect the calculated outdoor temperature value for thermoregulation,
low values indicate high speeds.
Setting range: [0 - 255]
Factory setting: [20]
To change the value of the previous parameters, proceed as described below:
- select TECHNICAL WEATHER COMPENSATION BUILDING TYPE or
OUTDOOR REACTIVITY
- set the desired value.
Note: The value of the calculated outdoor temperature used by the thermoregulation
algorithm is displayed in the INFO menu under FILTERED OUTDOOR TEMP.
REQUEST FROM ROOM THERMOSTAT OR POR (Heating Programming Timing)
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.
SELECTING THE COMPENSATION CURVE
The compensation curve for heating maintains a theoretical temperature of 20°C
indoors, when the outdoor temperature is b20°C and -20°C. The choice of the
curve depends on the minimum outdoor temperature envisaged (and therefore on the
geographical location), and on the delivery temperature envisaged (and therefore on
the type of system). It is carefully calculated by the installer on the basis of the following
formula:
KT = T.outlet envisaged - Tshift
20- min. design external T
Tshift = 30°C standard system
25°C floor installations
If the calculation produces an intermediate value between two curves, you are advised to
choose the compensation curve nearest the value obtained.
Example : if the value obtained from the calculation is 1.3, this is between curve 1 and curve
1.5. Choose the nearest curve, i.e. 1.5.
The settable KT values are as follows:
- standard system: 1.0-3.0
- floor system 0.2-0.8.
Using the REC10CH it is possible to set the selected thermoregulation curve:
- select TECHNICAL WEATHER COMPENSATION CLIMATIC CURVES
- select the heating zone and set the compensation curve.

OFFSET ON THE REFERENCE AMBIENT TEMPERATURE
In any event, the user can indirectly modify the value of the HEATING setpoint inserting an
offset on the reference temperature that can vary within the range -5-+5 (offset 0 = 20°C).

NIGHT COMPENSATION
If a timer is connected to the ROOM THERMOSTAT input, the NIGHT COMP function can
be enabled as follows menu TECHNICAL WEATHER COMPENSATION
CLIMATIC CURVES MAIN. In this case, when the CONTACT is CLOSED, the heat
request is made by the flow sensor, on the basis of the outdoor temperature, to obtain a
nominal ambient temperature on DAY level (20°C). The opening of the contact does not
produce a switch-off, but a reduction (parallel translation) of the climatic curve on NIGHT
level (16°C). Also in this case, the user can indirectly modify the value of the HEATING
setpoint inserting once again an offset on the reference DAY temperature (20°C) rather than
NIGHT (16°C) that can vary within the range [-5 - +5].

4.3 First commissioning
- Position the system’s master switch to the “on” position.
- Open the gas tap to allow fuel to flow.
- Adjust the room thermostat to the desired temperature (~20°C) or, if the system is
equipped with a chronothermostat or programmable timer or REC10CH set as an
ambient regulator, ensure that the thermostat or timer is “active” and set correctly (~20°C)

- When there is a heat request and the boiler is igniting, the icon appears on the display. The
boiler will start up and continue working until the set temperatures are reached, after which it
will then go back to standby.

Each time that the boiler is powered, an automatic vent cycle is carried out lasting
4 min. When the vent cycle is in progress, all heat requests are inhibited except for
domestic hot water ones when the boiler is not set to OFF, and a scrolling message
at the foot of the page appears on the main page of the REC10CH.
