Sleep Function - AERMEC GLF10N Manual De Uso E Instalación

SLEEP FUNCTION

The Sleep function in the thermostat is
available if the thermostat is interfaced
with a presence sensor (with normally
open logic) connected to its SP input. In
practice the function consists in chang-
ing the regulation setpoint of the fan coil
if the air-conditioned environment is not
The air side season changeover is inhibited when the SP input is kept closed; this function prevents incorrect status
changes due to the change of the setpoint
COMFORT FUNCTION
The set point of centralized systems in
which there are network connected fan
coils, is decided by a central unit. The user
may have the opportunity to increase or
decrease the setpoint according to the
table below.
FUNCTION ELECTRICAL RESISTANCE
In AUX mode is required for activation
of the accessory electrical resistance,
and its susceptibility to the user inter-
face VMF-E4
The standard operation of the accessory
provides resistance to his command for
ON-OFF. In order to control this type of
accessory you must first set up the confi-
guration of the dip in the 6-speed On and
set the switch in the "Aux".
The operation of the electrical resistance
occurs when there has been a request for
operation of the thermostat and the water
temperature is sufficiently low.
It is noteworthy that the resistance to
the startup of the thermostat is in the
OFF state, will then be activated only
if the water temperature is below the
threshold of qualification (which is 35
° C with normal bandwidth, 31 ° C with
band reduced).
THERMOSTAT SAFETY OF ELECTRICAL RESISTANCE
The control software verifies the correct
operation of the anomalous resistance
considering the following:
Thermal resistance
Absence of resistance
The thermal resistance is performed by
reading the NTC that detects the actual
occupied; i.e. decreasing if operating hot,
increasing if operating cold. This function
aims at saving energy. In this specific case,
if the thermostat card was connected to a
presence sensor, the logic of the SP input
occurs as follows:

The activation of the electrical resistance,
however, provides management of ven-
tilation as a function proportional to the
error but where is the minimum guaran-
teed speed V2.
This tax is due by the need to provide
adequate dissipation of heat generated by
joule effect resistance.
If the fan coil is operated with continuous
ventilation at the setpoint is reached the
electrical resistance will be turned off
while the fan, after the post purge phase
described below, will continue with the
minimum speed.
The operation of the electrical resistance
of the phases provides pre-purge and
Post-purge in relation to its activation and
deactivation:
Prepurge (20 "to Vminaux) is always with
the activation of the RE
Post-purge step is always the case the
temperature of the accessory.
The control of the absence of resistance
is given by checking the status of the fuse
F2 and the control of the temperature of
at least 50 ° C after 90 seconds of the load.

deactivation of the RE (60 "to Vminaux).
WARNING! prepurge (approxima-
tely 20 "Vminaux) is always with the
activation of the RE and the RE of ladi-
sattivazione post purge is always the
case (about 60" Vminaux).
The alarm of the resistance (the
combination of heat or lack) is a failure
that inhibits its operation and to resto-
re the activation must toglieretensione
the thermostat.
