3.3.5 Boiler Operation Mode Selection
This function is intended for selecting one of three modes of boiler operation.
І. House Heating: ON/OFF
When activating this mode the heating system will give priority to heating the line of
the central heating pump.
ІІ. Parallel Pumps: ON/OFF
When activating this mode the heating system equally distributes the heat carrier to
heating lines depending on temperature ranges assigned by the user.
ІІІ. Summer Mode: ON/OFF
When activating this mode the heating system will be functioning only to maintain the
temperature of the hot water supply pump line.
3.3.6 Pumps
This function allows setting up the temperature value whereby the Controller will
switch on the central heating pump or hot water supply pump to supply heat carrier to this or
other system. Hysteresis value in this case is the value that shows difference between the
preset temperature of pump switch on and boiler temperature dropping to the value whereby
the Controller will switch off the Central Heating pump.
а.) Pump Switch on Temperature: changes within the range of 30–95°С
b.) Pump Hysteresis: changes within the range 1–10°С.
3.3.7 Adjuster Menu
This function allows adjusting basic parameters of the Controller’s program.
3.3.7.1 Screw feeder alarm switch on temperature: 50–95°С.
This parameter ensures safe operation of the boiler and protects fuel bunker from
burn-up. In case of temperature rise on screw sensor higher than the preset one in this item,
the Controller moves to the emergency mode (burn-up in the feeder). The fan switches off,
the screw feeder switches on for the time period set up in Item 7.2. to push out burning fuel
from the bunker.
3.3.7.2 Screw feeder operation during alarm: 1–20 min.
This parameter is intended for setting up screw feeder operation time for fuel off-
loading during its burn-up. If, in a certain time period the temperature on the sensor does not
drop up to the appropriate one, the off-loading cycle will be repeated.
3.3.7.3 Factory Settings: factory reset NO/YES
This function allows carrying out factory reset.
Once factory reset is done it is required to set up the Controller’s parameters again.
3.3.7.4 Sensors Switch off:
І. Hot Water Supply Sensor: on/off
This function allows deactivating control of hot water circuit in systems where it is not
