mode not only of the learned channel but also all the other channels
on the receiver. In this way the receiver hysteresis can be customized
or an output can become PWM, even if the channel will later be
coupled to a plain non configurable thermostat.
‘
HySt
’: ROOM TEMPERATURE REGULATION HySTERESIS
It represents the hysteresis width used when an ON/OFF regulation has
been chosen (
‘OPWM‘= no
) or when the thermostat limits the floor
temperature. The factory default hysteresis is 0.2°C.
‘bP’
: PWM PROPORTIONAL BAND
The following parameter will be displayed only if ‘
oPWM
’ parameter
has been set to ‘
YES
’.
This parameter allows to customize the proportional band in the range
1.0 ..8.0 °C.
‘t int’
: INTEGRAL TIME
The following parameter will be displayed only if ‘
oPWM
’ parameter
has been set to ‘
YES
’.
This parameter allows to customize the integral time of the
proportional regulation in the range 0 ..180 minutes (5 minutes steps).
When set to zero, no integral action will be done.
‘PCyC’
: PWM CyCLE TIME
The following parameter will be displayed only if ‘
oPWM
’ parameter
has been set to ‘
YES
’.
This parameter defines the duration of each PWM cycle in minutes,
i.e. every how many minutes is the variable width pulse repeated.
‘PMIn’
: MINIMUM TIME PWM ON
The following parameter will be displayed only if ‘
oPWM
’ parameter
has been set to ‘
YES
’.
This parameter defines the minimum PWM pulse width i.e. the
minimum output switch-on time. When an electro-thermal actuator is
wired to the output, this parameter must be set with the actuator’s
travel time, otherwise ‘on’ pulses of a lower time respect to the travel
time would generate unuseful output actions. The parameter can be
set in the range 0 .. 15 minutes.
‘
tMIn
’: MINIMUM OUTPUT ON TIME
The following parameter will be displayed only if ‘
oPWM
’ parameter
has been set to ‘
no
’.
This parameter allows to reduce the number of ON/OFF cycles of the
output. This function is useful in case the chronostat drives a pellet
stove which cannot be switched On and Off for a too short time.
Once the receiver’s relay is switched On according to a heating
(or cooling) need of the room, it will not be switched Off until the
‘minimum On time’ is expired. The parameter can be set in 10 minutes
steps in the 0..90 minutes range.
The device is factory set with the ‘minimum On time’ to 0, i.e.
function disabled.
CONFIGURATION DEFAULT RESET
It is possible to reset the settings of the user menu, the advanced
menu and the schedule program in order to bring all the configuration
parameters of the chronostat to the default factory value.
