Notes:
(1)
the unit of measurement depends on P2
(2) Properly set the parameters corresponding to the regulators after modifying parameter P2
(3) the value depends on parameter P2 (0.1 °C or 1 °F)
(4) if parameter r8 is set at 1, the “energy saving” function and the defrosting functions will not be enabled
(5) the parameter has effect even after an interruption in the power supply that occurs while the device is switched on (5) the parameter has effect even after an interruption in
the power supply that occurs while the device is switched on
(6) the time established with the parameter is counted even when the device is switched off
(7) if parameter C1 is set to 0, the delay after the end of the cell probe error will be 2 min
(8) if parameter C2 is set to 0, the device will function as if parameter C18 were set to 0
(9) The parameter differential is 2.0 °C/4 °F
(10) if when the device is switched on, the condenser temperature is already above that established in parameter C7, then parameter C8 will not have effect
(11) the device verifies the mains voltage at established intervals with parameter C2; if there is a power cut, the count of the number of switch-ons aborted will be reset.
(12) the device memorises the defrosting interval count every 30 minutes; the modification of parameter d0 has effect from the conclusion of the previous defrosting interval (or the
activation of defrosting in manual mode)
