CHAPTER 3. REGULATIONS
3.1. Central heating regulations
3.1.1. Modulation on flow sensor
Parameter C/r=0 (default)
The regulation on flow sensor is between 25“C and the
value of parameter C.
In the menu structure you can set the maximum
permitted boiler flow temperature with parameter C
(default 82“C).
The burner blocks when the maximum permitted boiler
flow temperature (parameter C) is reached.
3.1.2. Modulation on return sensor
Set in the menu structure parameter C/r=1
The regulation on return sensor is between 24“C and the
value of parameter C.
In the menu structure you can set the maximum
permitted boiler return temperature with parameter C
(default 82“C).
- The burner blocks when the maximum permitted boiler
return temperature (parameter C – parameter C/r) is
reached.
- The burner blocks also when the boiler flow sensor
reaches a temperature of 90°C, whatever parameter C
has been set to.
3.1.3. Modulation on system sensor
You must connect the
system sensor, NTC
of 12kOhm @ 25°C,
to ports 4 and 5 of the
connector block,
mounted on the
electronics casing.
Set in the menu structure parameter C/r=1
The regulation on system sensor is between 24“C and
the value of parameter C.
In the menu structure you can set the maximum
permitted system temperature with parameter C (default
82“C).
- The burner blocks when the maximum permitted
system temperature (parameter C – parameter C/r) is
reached.
- The burner blocks also when the boiler flow sensor or
boiler return sensor reaches a temperature of 90°C,
whatever parameter C has been set to.
3.2. Thermostats
3.2.1. On/off room thermostat
You must connect the on/off thermostat
to the green connector block ports (1) -
(2)
The setpoint is made by the ’on-time’ and the ‘off-time’ of
the room thermostat.
Increasing setpoint
With heat demand the thermostat is closed and the
setpoint (desired boiler temperature) rises at a rate of
6°C per minute from 25’C until the maximum permitted
temperature is reached (parameter C).
Falling setpoint
With end of heat demand is the thermostat open and the
setpoint falls at a rate of 3°C per minute to the minimum
heating temperature of 25°C.
