WARNING:
When the regulation is set according to the remote sensor
' EHt ' and in case this sensor is missing or broken, the
temperature regulation will be performed according to the
internal sensor, even if the parameter remains set on ' EHt
HYS
' ' HYSTERESIS SETTING
This parameter sets the hysteresis, in °C, used in the temperature
regulation.
The parameter can be set in the range 0,0°C .. 5°C. The device
leaves the factory with the hysteresis set on 0,2°C.
WARNING:
Setting this parameter must absolutely be made by qualified
personnel because setting an inappropriate value might result
in wrong operation of the whole regulation system.
OPWM
' ': PWM OUTPUT REGULATION
Allows to choose whether the receiver output must be ON/OFF driven
or PWM (Pulse Width Modulation) driven.
With ON/OFF regulation (no) the programmable thermostat will
regulate the output with customisable hysteresis on parameter
' HYSt ', while with PWM regulation (YES) the programmable

thermostat will regulate the output.
The integrative regulation can be adapted to the different room with
several parameters: proportional band ' bP ', integral time 't int', PWM
cycle time ' PCYC ', Minimum time PWM ON ' PMIn '.
The device leaves the factory with parameter set on no.
The following paramenters will be displayed only if the ' OPWM '
parameter has been set to ' YES '.
bP
' ': PWM PROPORTIONAL BAND
This parameter allows to customize the proportional band in the range
1.0 ..8.0 °C.
The device leaves the factory with parameter set on +2°C.
t int
' ': INTEGRATIVE TIME
This parameter allows to customize the integral time of the
proportional regulation in the range OFF / 5 .. 180 minutes (5 minutes
steps). When set to OFF, no integral action will be done.
The device leaves the factory with parameter set on OFF.
PCYC
' ': PWM CYCLE TIME
This parameter defines the duration of each PWM cycle in minutes,
i.e. every how many minutes is the variable width pulse repeated.
The parameter can be set in the range 15 .. 60 minutes.
The device leaves the factory with parameter set on 30 minutes.
PMIn
' ': MINIMUM TIME PWM ON
This parameter defines the minimum PWM pulse width i.e. the
minimum output switch-on time.
