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the time set by the auxiliary heat source operation parameter G03 [sterilization cycle], the timed sterilization is withdrawn;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range of sterilization, and the cumulative operating parameter G04 [high temperature time of sterilization] is withdrawn from the timed sterilization;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 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
Set the start date, end date and timed period/mode of holiday home mode through the wire controller, and during the holiday home period, the unit will follow the set every day
Timing periods and modes to start and stop the crew at regular intervals.
When receiving the in-line controller holiday home mode shutdown command or holiday home mode ends, the unit exits holiday 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 smart grid function is turned on
N32 [Smart Grid Function] is set to "Use", and N01 [Power Mode] is set to "Automatic" to enable the smart grid function
Activation and control of the lower return pump
Prerequisite: [Lower Return Pump] is set to "Use"
[Next Return Pump Timing] is set to "Use":
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 timing sterilization setting for the lower return pump is enabled
Enabling and disabling the hot water function
Go to the advanced parameter settings, advanced parameter N11, you can enable and disable the hot water function
Setting of the single mode of heat pump cooling/heating
Enter the advanced parameter setting, advanced parameter N02, you can set the cooling and heating functions of the heat pump
Cascade settings
Wiring operation, see the "cascade" interface in the electrical connection diagram, and connect the cascade A1 and B1 communication lines of each module in parallel under the power-off state, that is, A1 and Al, B1 and B1 of each module are connected one by one in order;
DIP operation: address DIP: see the schematic diagram of the electrical connection, in the state of power failure, set the address of each unit module, address 0 is the main module, address 1 is the No. 1 submodule, and so on, and the display screen and network monitoring only need to be connected to the main module.
Cascade DIP wiring diagram
3. Set the number of wire controller modules: enter the advanced parameter N60, change the number to the parameter N60 [number of modules] to the corresponding number of modules, and each module is set to "use" (the corresponding parameter is N64-N71), and the maximum number of cascades is 8.
4. Set the number of hot water modules after cascading:
Prerequisite: When N11 [Hot Water Function] is set to "Use" on the online controller interface, and [Number of Modules] >1, the number of modules that can participate in hot water production is determined by setting N82 [Number of Hot Water Modules];
When the number of hot water modules ≥ the number of modules, all modules can participate in hot water production; The address of the module that can participate in hot water production is: 0 ~ [number of hot water modules] -1.
Force the external heat source to turn on
Prerequisites: [System Total Outlet Water Temperature Probe] is set to "Use", and [External Heat Source] M40 is set to "Heating & Hot Water".
Force on external heat source: Go to Settings,
Forced water tank electric heating on and hot water mode
Prerequisites [Water Tank Electric Heating] N20 is set to "Use", enter the settings,
Forced auxiliary electric heating to be turned on
Prerequisites [Auxiliary Electric Heating] M39 is set to "Heating & Hot Water", and then enter the settings
Adjustment of power mode
Go to advanced parameter N01
