Generator operating safety features in heating mode
- A safety device on the water temperature (installation return) prohibits generator operation if this temperature is
below the thermodynamic heating authorization threshold (parameter 36). In this case, only the boiler is authorised
to raise the water temperature and allow the generator to function, regardless of the outside temperature. The
activation of this safety feature is indicated by the flashing of the display.
- Generator operation is prohibited if the outside temperature is below the generator's shut-off threshold (parameter
20). Only the boiler is authorised.
8.1.3 - "ECONOMY" HEATING MODE
• The switch to "
ECO
" mode lowers the ambient temperature setpoint by a value than can be adjusted from 1 to 6 °K
(parameter 24).
• Switching from "
Comfort
" to "
ECO
" is accomplished either by hourly programming, weekly programming by zone or by
actuating the rotary knob for the entire installation.
• In the case of hourly programming, the user can activate a temporary override (1 hour + periods of 1 hour during the
current day) per zone.
8.1.4 - "ANTI-FREEZE" HEATING MODE (prolonged absence)
• Selection is made using the rotary knob on the control
unit for the entire installation.
• The resulting water temperature setpoint shifts to an
adjustable value via parameter 29. The heating
(gen boiler if required) is actuated according
to the ambient temperature setpoint, which can be
adjusted by parameter 25.
8.1.5 - SELF-ADAPTING HEATING SLOPE
• System activated by parameter 74 = 1.
• Principle: the theoretical slope calculated according to the parameters of the control equipment is automatically
corrected by the system by adding (or subtracting) a correcting coefficient (the value of which is displayed in parameter
90). This coefficient is determined by analysing, in terms of a 24-hour continuous operating period in "
Comfort
"
heating mode, the behaviour of the ambient temperature in relation to the setpoint temperature (in "
Comfort
" mode).
This analysis is also weighted by the difference between the setpoint and the outdoor temperature.
• Example:
(P)
= Theoretical
slope
(P + K)
= Slope increased with ambient temperature
below the setpoint
(P - K)
= Slope decreased with ambient
temperature above the setpoint
Note
:
Regardless of the slope, the resulting setpoint cannot
exceed the maximum temperature value of the water
(parameter 30) (possibly corrected according to the
ambient temperature).
Example:
To adjust the following parameters:
. Parameter 21 = 0°C
. Parameter 23 = 20°C
. Parameter 30 = 60°C
. Parameter 32 = 30°C
Theoretic slope value
P
=
= 1.50.
If the value of the coefficient
K
read on parameter 90 is “10” (hundredths), the actual slope becomes:
P
+
K
= 1.50 + 0.10 = 1.60.
The value of this coefficient is reset in the event of:
- deactivation of the system by parameter 74,
- re-initialisation of the parameters by parameter 60,
- an application change by parameter 70.
8.2 - COOLING MODE
Inactive
Note
: The selection of this mode, using the rotary knob, causes the system to shut down (“
OFF
”).
