b)
Pressure fan work parameters
Fan power
[Π100]
- this value defines power of the fan. When "Πr" parameter is set to
"0-10"
this is the maximum power of the fan
which can be achieved during the automatic fan control.
Automatic fan speed control
[Πr 1]
– it’s on, when this parameter is set to
"0-10"
and causes automatic fan speed reduction when the temperature of water in the boiler reaches the desired temperature. If this
parameter is set to
"-"
, the fan automatic smooth speed control is disabled and the fan can work with power set by
"Π"
parameter.
Setting parameter value in range from 0 to 10 means time in minutes of the smooth fan speed increase from 40% to a value of
"Π"
for
a smooth boiler start.
Fan work time
[Πn 5]
- time of turning the fan on for a while, to remove accumulated gases. Setting the parameter to
"-"
turns this
function off.
c) Circulating pump parameters
Circulating pump launch temperature
[P144]
- temperature of water in the boiler, which causes start of the circulating pump.
Circulating pump works independently from the control process and is launched additionally in case of boiler overheat.
Circulating pump launch hysteresis
[Ph 4]
- this parameter defines what value should temperature decrease by, below circulating
pump launch temperature, to turn the pump off.
Pause time between circulating pump 30 second work periods
[Pc 2]
- in
STOP
mode or when room thermostat circuit is open; the circulating pump is launched for 30 seconds, to mix water in heating
circulation. This parameter defines time between launches of the pump.
Setting the parameter to
"-"
turns this function off.
