III.b.17) About the program
When this option is selected the display will show the software version of
the active valve module.
III.c)Valve 2
All settings for valve 2 are made in the same way as in the case of valve 1.
III.1.
Pump activation temperature
The option is used to set the activation temperature for central heating and
domestic hot water pumps (the temperature is measured on the boiler). None
of the pumps will operate if the temperature is lower than the preset one. If the
actual temperature is higher than the preset one the pumps are working but
they operate depending on the operation mode (see: pump operation modes)
III.2. Boiler hysteresis
This option is used to set the hysteresis of the set temperature. This
is a difference between the temperature of entering the support cycle,
and the temperature of return to the operation cycle (for example: when
the set temperature has the value of 60ºC, and the hysteresis is 3ºC,
switching into the support cycle will proceed when the temperature
increases to 60ºC, while return to the operation cycle will proceed when
the temperature decreases to 57ºC).
III.3. HUW hysteresis
This option is used to set the hysteresis of the set temperature in the
