1)
When the lower tank temperature T2 equals “TS1 calc”, the compressor is switched off
and if “TS1 calc” < manual setting value TS1, the electric heater will operate according to
the following logic:
•
ON: when the upper tank temperature T3 ≤ manual value TS1 -3°C (parameter 33,
default 3°C), the electric heater is switched on;
• OFF: when the upper tank water temperature T3 reaches the set temperature TS1
manual value + 1°C.
2)
•
ON: when the ambient temperature ≤ -10°C or > 44°C;
• OFF: when the ambient temperature
≥
-8°C or < 42°C.
3)
•
ON: when there is high pressure or low pressure protection for 3 times within 30 min;
• OFF: when pressure protection occurs for the third time, the error code will be dis-
played, and this protection cannot be recovered unless the supply is disconnected.
• Therefore, the electric heater keeps running until the set temperature is reached, and
then it switches off.
4)
•
ON: when in defrost (only if parameter 20 is set to 1=on) or disinfection;
• OFF: when exiting defrost or disinfection.
11.5.2. Turned ON or OFF - Condition 2:
1)
When the unit is switched on and the electric heater button on the control panel has been
switched on manually:
•
ON: The compressor running time exceeds the E-heater delay time (parameter 3), and
the tank water temperature above T3
≤
TS1 manual - 3°C;
• OFF: Tank water temperature is higher T3
≥
TS1 1°C.
11.5.3. Turned ON or OFF - Condition 3:
1)
When the unit is switched off:
•
ON: If the electric heater button on the control panel has been manually turned on
when the unit is OFF, the electric heater will operate until the water in tank T3 reaches
the set temperature TS2;
• OFF: The electric heater button on the control panel has been manually turned off or
the water in tank T3 reaches the set temperature TS2.
