Enable the climate curve


Customize curve settings


When the climate curve cannot meet the user's customization needs, the user can set the custom curve through the following methods:


Custom curve (curve 9): The corresponding curve temperature can be set according to the requirements (the end value of the ambient temperature exceeds the range);


The parameters of the refrigeration custom climate curve are as follows: refrigeration ring temperature 1, refrigeration temperature output temperature 1, refrigeration ring temperature 2, and refrigeration temperature 2 (the two points are calculated linearly, and the endpoint value is taken outside the two points, formula: y = kx +b);


Set the relevant customer parameters to M10-M21.


Curve 9 is a linear calculation as follows:


The refrigeration operation follows the following linear diagram:


Among them, Tenv_cl_max: MAX (parameters [M14], [M15]).


Tenv_cl_min: MIN (parameters [M14], [M15]).


TcS_end: MIN (parameters [M16], [M17]).


TcS_start: MAX (parameters [M16], [M17]).


The heating process follows the following linear diagram:


Among them, Tenv_ht_max: MAX ([M18], [M19]).

Tenv_ht_min: MIN(M18,M19)

ThS_end: MIN(M20,M21)

ThS_start: MAX(M20,M21)


Inline controller settings:


Refrigeration curve settings


Parameters [M14], [M15], set the ambient temperature range of the refrigeration curve, parameters [M16] , [M17] sets the temperature range of the refrigeration effluent


Heating curve settings


Parameters [M18], [M19], set the ambient temperature range of the heating curve, parameters [M20], M21Set the temperature range of the heating curve and the outlet water.


Scheduled sterilization run settings


Timing sterilization operation logic:


Prerequisites: Parameter N11 [Hot Water Function] needs to be set to be enabled, and parameter G01 [Timing Sterilization] to be enabled;


Parameter G02 [Sterilization Temperature]: 65°C by default


Parameter G03 [Sterilization Cycle]: 48 hours by default


Sterilization conditions: When the "sterilization time point" of the timed sterilization setting is reached or the sterilization is started in the holiday away mode, the unit will turn on the hot water sterilization;


The first stage: the unit turns on the hot water of the compression mechanism, the temperature of the water tank reaches the target temperature of the hot water, and the compressor is stopped to enter the second stage; If the compressor is in the state of hot water constant temperature shutdown, it will enter the second stage immediately;


The second stage: the unit turns on the auxiliary heat source sterilization and runs the sterilization at a regular time;


After the time set by the auxiliary heat source operation parameter G03 [sterilization cycle], the timed sterilization is withdrawn;


The temperature of the hot water tank THWt is in the high temperature range of sterilization, and the cumulative operating parameter G04 [high temperature time of sterilization] is withdrawn from the timed sterilization;


The temperature of the hot water tank THWt ≥ the sterilization temperature, and the auxiliary heat source is turned off; The temperature of the hot water tank THWt< the sterilization temperature is -2 °C, and the auxiliary heat source is turned on;


Note: 1) The electric heating of the water tank is enabled, and the auxiliary electric heating and external heat source are not turned on; The electric heating of the water tank is not activated, and the auxiliary electric heating or external heat source is turned on (the auxiliary electric heating and the external heat source cannot be enabled at the same time, otherwise it will not be turned on);


During the preheating/drying of floor heating, the timing sterilization function is not performed;


The buffer tank sensor is enabled


The position of the upper and lower sensors of the buffer tank sensor on the motherboard (A12) (A13) at the position of 26,35 on the motherboard (as shown below), after enabling the sensor, the corresponding sensor needs to be plugged in at the corresponding position of the motherboard. Then enter the advanced parameters on the line controller, the upper temperature probe of the N45 buffer water tank, and the lower temperature probe of the N46 buffer water tank to be enabled


The buffer tank sensor is enabled


Instructions for enabling the Solar Temperature Probe Control


If you are using a solar water heater in parallel with our machine, you will need to install the solar temperature probe in the accessory and enable parameter N22 (Solar) 0 Disable/1 Enableparameter N41 (Solar Temp. Sensor) 0 Disable/1 Enable, select 0 if not.


(as shown in the figure above) 30 position, the position on the motherboard (A14) needs to be plugged in with the corresponding sensor after the sensor is enabled. Then go to the advanced parameters on the controller


Solar water pump control


[Solar Temperature Probe] is set to "Disabled", and when a solar signal is detected and the temperature of the hot water tank is less than the set value minus the difference, the sun will be turned on


Turn off the solar pump until the solar signal is disconnected or the temperature of the hot water tank reaches the set value.


[Solar Temperature Probe] is set to "Use", when the solar temperature reaches the allowable opening temperature and the temperature of the hot water tank is less than the set value, the difference is reduced


Turn on the solar pump until the solar temperature is lower than the shutdown temperature or the hot water tank temperature reaches the set value, and turn off the solar pump.


The underfloor heating inlet water temperature sensor is enabled


When the wire controller selects dual zones and needs to install floor heating, you need to set the parameter N36 to 1 to use. At the same time, the sensor needs to be plugged in at the position of the motherboard (AI6C), as shown in the position of the motherboard 29 in the figure above.
