Menu / State
Te (exter.):
External input air temperature in °C.
Tr (return
) : Return air temperature in °C..
Tx (expelled)
: Exhaust air temperature in °C.
Ti (input.):
Input air temperature in °C.
Tw(water):
It is on when post-heating is set by water coil and indicates its temperature in °C.
Wat.nofrost:
It is on when post-heating is set by water coil and indicates whether the "no-frost" mode is
on. The no-frost function of the coil is triggered when the temperature taken by the Tw probe drops
below 1 °C and then goes off when the temperature returns above 3 °C. When temperature detected from
Tw is below 3° the control valve is fully open in order to prevent ice from forming inside the element.
Afterwards, if Tw will go below 1°, fans will be stopped.
Anti-frost:
"Anti-frost" function state (ON-OFF). The anti-frost function is triggered automatically when
the temperature taken by the Tx probe drops below 1 °C and then goes off when the temperature returns
above 3 °C. When it is on, two options are available according to the factory settings:
_in case the anti-frost is operated by a preheating resistance, this is enabled until 3°C are achieved;
_ in case the anti-frost is operated by adjusting the fan speed, the input fan will be inhibited and, at the
same time, the return will be forced to its maximum speed. All the above until 3°C are achieved. This in
order to avoid the formation of ice in the exchanger.
Fan (supply):
Input fan speed; this value is expressed as:

rounds per minute (RPM), when fans with tachimetric signal are installed;

percentage, when variable speed fans are installed without tachimetric signal (Off when the fan
is off);

Off, 1 ,2 or 3 for 3-speed fans.
