S
ENSORS
This option allows defining the type of the sensor connected:
•
none – no sensor connected to the input – the sensor will not be selectable in all parameters.
•
KTY – KTY-type temperature sensor connected to the input.
•
PT1000 – PT1000 temperature sensor connected to the input.
Note: If the user sets the sensor to "none" while it has been used in the operation of pumps, the pumps
operating in temperature and delta modes will be shut off and the turn-on threshold will be deactivated for
the pump working in circulation mode
P
UMP OPERATING TIME COUNTER
The function allows the user to preview the pump operating time counters to check numbers of days, hours
and minutes of operation. The controller counts the seconds of operation of individual pumps and only after
they add up to a full hour the controller stores the counter indication in the non-volatile memory. Therefore,
any shut-off, power supply failure etc. occurring before 3600 seconds are counted will cause that, when
restarted, the counter will indicate the number of full hours counted only. Pressing of pulser knob allows the
user to reset the counter.
