HEATING ELEMENT
The electrical heating element is a device used to provide
support where necessary in the heating mode.
SELECTION
If provided for in the con fi guration, the heating element can be
selected in the heating mode by pressing the Sel key.
ACTIVATION
If use of the heating element is selected by the user, it will be
activated on a call from the thermostat based on the room
temperature
NB:
switching it on will force the fan on as well
WATER CONTROL
Enabling of the heating element is tied to the water temperature.
The related enabling logic is described below
The enabling signal will not be given if the water sensor is
either not present or disconnected
DISPLAY
The display will show the following information
■
heating element selected by the user: steadily lit
symbol
■
active heating element: fl ashing symbol
The display shows fan speed (with indication of “automatic”
logic if proper) enabled or selected (in case of stand-by fan)
Extra low speed
Low speed
Medium speed
High speed
NB
: if the active speed is different from the one selected by
the user (in the case of a forced override), pressing the
button once will cause the latter to be displayed;
pressing again will change this setting.
VALVE
The controller can govern 2 or 3-way On/OFF type valves with
actuator featuring 230 V.
OPENING
The valve opening is controlled according to the operating
setpoint and air temperature setpoint
WATER CONTROL
The checking of water temperature to enable valve opening
is a function that concerns only con
fi gurations with 3-way
valves and heating element. In such con fi gurations the water
temperature will be checked in the following cases:
■
Heating with heat element: operation of the heating
element will force the fan to switch on; it is therefore
necessary to prevent excessively cold water from passing
through the unit.
■
Post-ventilation due to switching off of the heating element:
this function will be maintained until the set time has
elapsed, even if the operating mode is changed. During
post-ventilation the water temperature enabling signal will
coincide with the one seen for fan operation.
DISPLAY
The active valve indication on the display will be shown by
the symbol
