When the ambient air temperature is within certain range (for example above 25
malfunctioning, "TS1 calc" is constantly recalculated by the controller's logic. This occurs despite of what value "TS1 set" is
adjusted by the user via control display. In this case:
•
If the lower tank temperature T2 = "TS1 calc" < "TS1 set" compressor is OFF and E-heater is ON
automatically to the moment when T2 reaches "TS1 set".
•
If the "TS1 calc" > "TS1 set" = T2, compressor is OFF and E-heater is OFF.
For running the appliance bellow -10
heater only!
7.3.2. "Boost mode"
When the heat pump is running, press this button
and the electrical heater will work according to the control program (parameter 3) together with the compressor until TS1 is
reached.
7.3.3. "E heater only"
If the E-heater button
the E-heater will work only, until the upper tank temperature Т3 (Fig. 3a) reaches the setting temperature TS2 adjusted by
the customer via control display;
7.3.4. "Antifreeze mode".
When the unit is at OFF status and if lower tank water temperature T2 ≤ 5°C (tank water frozen protection) E-heater
will works only, until lower tank temperature T2 (Fig. 3a) ≥ 10°C or the unit is turned on.
7.3.5. "Defrosting"
The icon indicates that the defrosting function is enabled. This is an automatic function, the system will entry or exit the
defrosting according to the inner control program.
In "Defrosting regime", E-heater will work, only if the parameter 20 is set to 1=on.
7.3.6. Disinfection weekly cycle
The E-heater will start each week at the setting time (parameter 13) automatically, regardless if the machine is on or
off (in standby).
When upper tank temperature T3 ≥ TS3 (parameter 4 = 70
temperature T3 ≤ TS3-2°C, the E-heater starts. The upper tank temperature T3 is kept in range TS3-2°C to TS3 for the set
disinfection time t2 (parameter 5 = 30min by default), then the unit quits the disinfection. It's possible to set the interval
between the disinfection cycles (parameter 21 = 7days by default).
7.3.7. Pump anti-block function:
When the pump stops for 12 hours, it will be forced to run for 2 min.
7.3.8. Fan ventilation
The icon indicates that the fan ventilation function is enabled. When the heat pump is ON, press this button
hold it for 5 seconds to enable or disable the fan ventilation function. If this function is enabled the fan will continue working
to ventilate the air, even when the water temperature reaches the set point and the unit enters standby mode. If this function
is disabled the fan will stop, when the water temperature reaches the set point and the unit enters standby mode.
