8. Reading correction - tank temperature
This is the value which is added or deduced from the measured temperature. it allows
for correction of temperature difference between the sensor placed on the pipe and
water temperature.
9. Central heating pump operation / test
it shows current pump condition, calculated by the controller (0 or 1).
Outlet testing function can be switched on by pressing the knob. After 10s of inactivity
or after pressing the knob again, the controller resumes operation according to its
settings.
10. Hot water tank loading pump operation / test
it shows current pump condition, calculated by the controller (0 or 1).
Outlet testing function can be switched on by pressing the knob. After 10s of inactivity
or after pressing the knob again, the controller resumes operation according to its
settings.
A list of all the settings has been shown below.

10. CONTROLLER OPERATION
The controller constantly monitors tank and boiler temperatures.
Central heating pump will be switched on, if temperature exceeds settings by half of the set
hysteresis value T
boiler
Central heating pump will be switched off, if temperature falls below settings by half of the set
hysteresis value T
boiler
The decision on switching hot water tank pump, on the other hand is taken in two steps:
• Tanks should be heated, if tank temperature is lower than the set value about at least
half of the hysteresis value, T
priority is on, operation of central heating pump is interrupted.
Tank heating can be interrupted, if tank temperature is higher than the set value about
at least half of the hysteresis value, T
• The pump can be switched off without risking cooling down, if heat source temperature
