Hot water thermostat control, parameter 160. This parameter takes two values: "0" •
and "1". Value "0" indicates that the appliance's "activation/deactivation" tempera-
ture is to be read by the water probe at the appliance’s INTAKE. Value "1" indicates
that the appliance’s "activation/deactivation" temperature is to be read by the wa-
ter probe at the appliance’s OUTLET.
Water set-point, parameter 161: this parameter sets the water temperature that, •
when reached, causes the appliance to be deactivated (when the power modula-
tion is not active - parameter 181)
Water differential, parameter 162: this parameter represents an interval in degrees •
that, when added to the set-point, defines the temperature at which the appliance
is reactivated. This parameter is used only if the power modulation is NOT active
(parameter 181).
The appliance functions by heating the water until it reaches the set-point temperature.
At this point, if the power modulation is not active (parameter 181), it switches off. The
temperature of the water goes down again until it reaches the temperature correspond-
ing to "set-point + differential"; when this is reached the appliance switches on again.
Example:
Thermostating: reading from inlet sensor.
Parameter 181: 0 (power modulation NOT active)
Set-point: +40.0°C
Differential: - 2.0° C
The appliance is functioning: the water in the plant heats up until it reaches the •
set-point temperature = +40°C.
The appliance switches off: the water in the plant, returning from use, becomes •
progressively cooler, until it reaches a temperature of 38°C = 40°C - 2°.
The appliance switches on again, and the plant water heats up again.•
The cycle is repeated.•
The following procedure illustrates in detail how to configure the parameters on the elec-
tronic board inside the appliance.
If the procedures for how to access the knob and menus are not familiar, see paragraphs
"Display and knob" and "How to access the menus" and following.
To set the parameters of menu 3:
You will need: the appliance on and access to the electrical panel, see "Display and
knob".
Access menu 3. The display shows the first parameter of the menu, number 160.
Turn the knob clockwise to scroll through the parameters: 3.160, 3.161, 3.162; lastly 1.
the letter E is shown.
Press the knob when a parameter is displayed to select it, or when E is displayed to 2.
exit the menu.
For example, to set parameter 161 (hot water set-point), proceed as follows:3.
· Select the parameter: turn the knob until the display shows 3.161;
· Press the knob to access the value of the parameter; the display shows the previ-
ously set value, which flashes, for example 40.0 °C;
· Turn the knob to modify the value of the parameter;
· Press the knob to confirm the value selected; the display shows the current pa-
rameter again, 3.161. The new value for this parameter has been set.
If other parameters are to be modified, proceed as described previously, and then 4.
exit from the menu by pressing the knob on the letter E.
