The type of control can be set in the control button belt (Figure 8).
3.2.6.1
Acond Therm® - AT button
The most economical and comfortable regulation system. The pump calculates the lowest
necessary temperature of the domestic hot water according to the needs of the building. This
system is the most economical option for regulation and saves 15 to 35% of energy compared
to other systems. The „
AT always
“ check box ensures that after each restart after a power
failure, the system switches to AcondTherm® control.
For the proper function of the AcondTherm control, the heating system in the
room with the spatial thermostat must not be equipped with thermostatic heads
or other superior regulation. If this is not respected, we recommend using the
Equitherm or Standard control.
3.2.6.2
Equipment - EQUIV BUTTON
The temperature of the water in the heating system is determined by the outdoor temperature.
The disadvantage of this regulation is that the curve of the required return water temperatures
must be set in such a way that even in the worst outdoor conditions (wind, rain, snow) it
ensures the desired air temperature in the building. This is usually unnecessarily high, causing
an increase in electricity consumption.
3.2.6.3
Manual input – ST button
Constant domestic hot water temperature set in the heating system – this option is mainly
intended for service purposes or for installing temperature control in rooms by the superior
system.
