Description of the climate curve setting

Explanation of the climate curve

The climate curve (high temperature climate curve, low temperature climate curve) of the unit has a corresponding outlet temperature in a specific temperature range, and the high temperature curve or low temperature curve can be selected according to the needs of customers.

After selecting one cooling or heating curve, the outlet water temperature of the unit will be consistent with the temperature set by the curve.

The custom curve of the unit can be set according to the customer's wishes, and the ambient temperature and the corresponding effluent temperature can be set by themselves, and the unit will operate according to a linear relationship.

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】)

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the time set by the auxiliary heat source operation parameter G03 [sterilization cycle], the timed sterilization is withdrawn;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range of sterilization, and the cumulative operating parameter G04 [high temperature time of sterilization] is withdrawn from the timed sterilization;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);

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. The operation of the wire controller is as follows

Instructions for the operation and setting of the underfloor heating preheating function

Prerequisites: Parameter N36 floor heating inlet water temperature probe activated

Prerequisites: Parameter N36 floor heating inlet water temperature probe activated.

Logic diagram of floor heating preheating:

F1: Parameter M55 [floor heating preheating interval], generally 30 minutes, can be adjusted and modified

F2: Warm-up shutdown duration, 5 minutes

Parameter M58 [Floor Heating Water Temperature Difference] 5 °C, Parameter M59 [Floor Heating Room Temperature Difference] 1 °C

Running logic description:

When preheating, the running time meets the F1 time, and the compressor stops; When the downtime time reaches F2, the compressor restarts;

Total effluent temperature≥ preheating target + unloading difference, stop the compressor; The total effluent temperature < the preheating target-energy loading difference, and the compressor is turned on

When the temperature of the local heating inlet water is ≥ the preheating target, the three-way valve 3 is closed, and the three-way valve 3 is ON output; When the temperature of the local heating inlet water is < the preheating target - parameter M58 [floor heating water temperature difference] or parameter M59 [floor heating room temperature temperature difference], open the three-way valve 3, and the three-way valve 3 is OFF output;

When the floor heating preheating time reaches [floor heating preheating duration] or manually turns off the floor heating preheating and exits the floor heating preheating;

Note: When the floor heating is preheated, the auxiliary heat source is not turned on, and the timer power on/off, holiday home mode, and holiday away from home mode are invalid

Floor heating preheating can be manually enabled by the online controller, and the user parameter settings can be accessed, and the opening method is as follows:

Meaning of parameter representation:

Underfloor heating preheating temperature (parameter M55): the target temperature of underfloor heating preheating, which is measured by the underfloor heating inlet water temperature probe. The value of this parameter can be modified

Underfloor heating preheating interval (parameter M56): The underfloor heating preheating operation interval, after which the compressor will be shut down for 10 minutes.

Floor heating preheating duration (parameter M57): The total duration of floor heating preheating operation, after the unit reaches the set duration, the floor heating preheating function will be turned off.

The enabling operation is shown in the following figure to enter the advanced parameter settings

Holiday mode is on

Holiday away from home mode

Set the start and end dates of the holiday away from home via the wire control During the holiday absence, the unit runs the heating/hot water production at a lower target water temperature,

To meet the needs of waterway anti-freezing and energy saving: if the unit has a regular sterilization function, the unit will only perform a sterilization on the last day of leaving home on the holiday.

When receiving the command to turn off the holiday away from home mode of the wire controller or the holiday away from home mode ends, the unit exits the holiday away from home mode and resumes normal operation.

*Holiday away from home mode and holiday home mode are mutually exclusive and cannot be run at the same time, and holiday away from home mode has a higher priority than holiday home mode

The hot water temperature and heating temperature of the holiday away from home need to enter the advanced parameters (M37 holiday away from home heating) and (M38 holiday away from home heating) to set.

Holiday at home mode

When the time reaches the opening time point of the lower return pump set by the user, the lower return pump is turned on, and it will continue to run for a period of time and then shut down.

[Sterilization of the lower return pump] is set to "Use":

When the unit enters the timed sterilization and the temperature of the hot water tank reaches the sterilization temperature, the difference is reduced (if the unit does not have a water tank for electric heating, the temperature of the hot water tank only needs to be reached

58°C), turn on the lower return pump until the unit exits the regular sterilization or the lower return pump continues to run for a period of time and then turns off the lower return pump. Here's how to enable the settings,

The lower return pump function is turned on

The lower return pump is switched on and set at a regular interval
