By changing hydraulic scheme connection will be changed also control of pump output and boiler configuration.
Therefore, it is very important that software setting of hydraulic schema is identical with existing boiler installation in
central heating system. In the basic memory of control unit are 4 basic schemas and schemas intended for operating
with Expander AK4000E. On demand, it is possible to add Expander schemas via AK4000M modul (pic.8). Updated
schemas for Expander AK4000E can be found on www.vigas.eu

Schema 1 is designed for boiler with accumulators tank. „LADOMAT“
provides reverse water protection. Pump is connected to the boiler control
and works continuously at temperature over 40°. Requested temperature
is possible to set up to 85° (chap.13.1.4). T3 input on power board
AK4000S is used to connect thermometer KTY to measure temperature in
accumulator.
Attention: Schema 1 does not allow to connect T3 – indoor thermostat!
Schema 2 is designed for central heating systems, where reverse water
protection provides external control system. Pump is connected to the
boiler control unit and works in pulsating wave depending on the boiler
water temperature. T3 contact on power board AK4000S is used to
connect indoor thermostat.
