- mode
[Pr 0]
– continuous work.
- mode
[Pr 1]
- pomp work depends on additional thermostat work mode. In
[Fc 0] mode central heating pump is turned on when room temperature is too low
(additional thermostat connection shorted or room temperature lower than temperature
set with additional thermostat knob). The pump is turned off when room temperature
reaches desired value. In [Fc 1] mode central heating pump is turned on when
measured exhaust gas temperature is higher than temperature set with additional
thermostat knob. The pump is turned off when exhaust gas temperature drops below
the set temperature.
- mode
[Pr 2]
– in this mode the central heating pump will turn on only when the
controller is in WORK mode.
Central heating pump pause time [Pc--]
– when boiler temperature exceeds
temperature set with
[P 65]
parameter and pump work mode doesn't allow turning the
pump off (e.g. thermostat contacts open) the pump can be periodically turned on for 30
seconds in order to move water in heating installation. This parameter sets pause time
in minutes between pump work periods. Setting this parameter to „--” disables this
function.
Central heating pump turn off delay [Pd 2]
– central heating pump stopping too
early can cause temperature rise in the boiler and cause its overheating. This
parameter allows setting central heating pump turn off delay. Setting this parameter to
„--” means that the pump will be stopping without delay.
6.3. Boiler work temperature setting.
Minimal boiler temperature [L 65]
- minimal temperature, which you can set with the
boiler thermostat knob.
Maximum boiler temperature [H 90]
- maximum temperature, which you can set with
the boiler thermostat knob.
Boiler temperature hysteresis [h 5]
- this parameter defines what value should
temperature of water in the boiler decrease by, below temperature set with the
thermostat knob, to turn the pressure fan on.
6.4. Boiler overheating protection.
Boiler overheating temperature [A105]
- value, exceeding which causes permanent
turn off of the pressure fan and launch of the circulating pump, to prevent boiler
overheating. Overheating mode is indicated by boiler overheating indicator and by
displaying error
[E 2]
on the display. It can be turned off by pressing STOP button, but
only when temperature decreases below boiler overheating temperature. Pressure fan
turning off occurs also in case of damage of the boiler temperature sensor, which is
displayed on the display by error
[E 1]
.
