and in the user parameter menu there is only the boiler thermostat set temperature
displayed.
[ur 1] value – hot water pump working with priority
[ur 2] value – hot water tank working without priority
[ur 3] value- means controlling of the returning water mixing pump in the boiler with
the launch temperature of [u 50] and hysteresis [uh 5].
4. Setting of boiler work temperature range
Minimum boiler temperature [L 40] - minimum temperature which can be set with
the boiler thermostat knob.
Maximum boiler temperature [H 90] - maximum temperature which can be 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, so that the fan turns on.
5. Protection against boiler overheating
Boiler overheating temperature [A 99] - value, exceeding which causes permanent
turn off of the fan to prevent boiler overheating. After the temperature increases
above 80˚C the central heating pump is turned on to cool down the boiler.
Overheating mode is shown by indicating error [E 2] on the display. It can be
turned off by pressing STOP button, but only when temperature decreases below
this temperature.
Fan turn off also occurs in case of damage of the boiler temperature sensor which
is shown on the display with error [E 1].
STB - the controller has additional protection against overheating which is
independent from the processor. In case the temperature increases over 95°C, the
control process is turned off by turning the fan off and launching the central heating
pump. The fan and the pump are turned on to the control process again when
temperature drops below 89°C.
STB circuit enables more precise boiler work control and reduces overheating
possibility.
6. No fuel
No-fuel testing time during fuel firing start [Fd60] - after switching to WORK mode,
if water temperature does not increase by 5°C in programmed time, the control
process will be turned off and the display will show the message: [FUEL].
You can return to previous mode by pressing STOP button. No fuel testing time
during fuel firing is finished after the set temperature is achieved.
No-fuel testing time during work mode [Fb30] - in WORK mode, if temperature of
water in the boiler decreases below temperature set with the thermostat, by
hysteresis value, and does not increase by 5°C in the programmed time, the
control process will be turned off and the display will show the message: [FUEL].
You can cancel the alarm by pressing STOP button.
